OK, this is very positive. In just one hour last night I managed to make a bunch of alien blips and blops using PythonScore. Now for the next step.

Say we have a pattern library in python that can be used alongside PythonScore. It's great for generating score event but what if you also want to be able to define a different envelop of arbitrary segments for each note? What if you want the envelop function to be generated by a python module? Would one use tables for this? Not so elegant I think. What are the options? I

Thanks

Are you not going to share said alien blips? A bit of extra-terrestrial audio would be nice.

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

If that's of use, I can post some more of the code or create a more

Hope that helps!

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Cheers,

If that's of use, I can post some more of the code or create a more

Hope that helps!

Hi Peiman,

I think it depends on the complexity of what your'e trying to
generate. The python code I had posted is a little lengthy but it's
doing quite a bit.  I've attached a CSD that is an excerpt of one of
the sound mass groups from my current piece.  The code uses 12
different performer objects in two different PerformerGroup objects (8
in the groupB64A, 4 in groupHorn).  The code generates glissandi such
that the group starts at a single pitch, then glissandi within a
growing random range, then converge into a major chord.  The glissandi
values have a bit of gentle variance added to get the texture to be a
little more lively.

This example though might not fall in line with the kind of material
you're thinking about, but at least it's an option that's there.  As a
side note, as I know you've been looking at the SuperCollider Patterns
library, the use of tied notes in Csound together with a note
generator is pretty much the same as what happens with using Patterns
with PMono and PMonoArtic.  The former involves absolute time values
for notes, while the latter operates with a delta time model.   Both
operate to update values for an instance of an instr/SynthDef over
time.

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Cheers,

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

Hope that helps!

Here is another approach:

https://gist.github.com/jacobjoaquin/5413575

I feel I can reduce this example further, and when I do, I'll include it as an example case with PythonScore. In the meantime, here's the explanation of how it works.

Envelope shapes are generated as tables. They are created dynamically in score. Since we don't want tables overwriting tables as they're being played, I created the table_cycler that cycles through a range of table indexes every time a new table is created. In this case, the range is between 100 and 120.

table_cycler = cycle(xrange(100, 120))

The function that handles this is gen_envelope(). It takes a list of envelope points, and reformats it into a GEN07 "f" event. The args are the same as GEN07, but only the envelope data, as the first 5 "f" event pfields are automatically handled:

def gen_envelope(*args):

    global table_cycler

    table = table_cycler.next()

    L = ["f", table, score.cue.now(), 8192, -7] + list(args)

    score.write(" ".join(str(i) for i in L))

    return table

That function returns the number of the table generated. So a value between 100 and 120. If you watch the table numbers during a performance, you'll see it cycle through this range.

Now, one can pass an arbitrary number of envelope points. The first 5 notes in the score demo this explicitly:

with cue(0): note(4, 0.707, 1000, gen_envelope(0, 8092, 1, 100, 0))

with cue(4): note(1, 0.707, 700, gen_envelope(0, 100, 1, 8191, 0))

with cue(5): note(1, 0.707, 400, gen_envelope(1, 8192, 0))

with cue(6): note(1, 0.707, 100, gen_envelope(0, 100, 1, 100, 1, 7991, 0))

with cue(7): note(1, 0.707, 200, gen_envelope(0, 8092, 1, 100, 0))

For the rest of the piece, it auto-cycles between a frequency pattern and an envelope pattern.

Best,

Jake

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

This is elegant. Do you know if there is currently a limit to the number of table points manually defined in the score?

If not, then there is room for much experimentation. One can even apply things like masking to tables. This then calls for a set of python classes for dealing with different table functions and so on.

I'll play with both yours and Steven's solution today and post my verdict!

Here is another approach:

https://gist.github.com/jacobjoaquin/5413575

I feel I can reduce this example further, and when I do, I'll include it as an example case with PythonScore. In the meantime, here's the explanation of how it works.

Envelope shapes are generated as tables. They are created dynamically in score. Since we don't want tables overwriting tables as they're being played, I created the table_cycler that cycles through a range of table indexes every time a new table is created. In this case, the range is between 100 and 120.

table_cycler = cycle(xrange(100, 120))

The function that handles this is gen_envelope(). It takes a list of envelope points, and reformats it into a GEN07 "f" event. The args are the same as GEN07, but only the envelope data, as the first 5 "f" event pfields are automatically handled:

def gen_envelope(*args):

    global table_cycler

    table = table_cycler.next()

    L = ["f", table, score.cue.now(), 8192, -7] + list(args)

    score.write(" ".join(str(i) for i in L))

    return table

That function returns the number of the table generated. So a value between 100 and 120. If you watch the table numbers during a performance, you'll see it cycle through this range.

Now, one can pass an arbitrary number of envelope points. The first 5 notes in the score demo this explicitly:

with cue(0): note(4, 0.707, 1000, gen_envelope(0, 8092, 1, 100, 0))

with cue(4): note(1, 0.707, 700, gen_envelope(0, 100, 1, 8191, 0))

with cue(5): note(1, 0.707, 400, gen_envelope(1, 8192, 0))

with cue(6): note(1, 0.707, 100, gen_envelope(0, 100, 1, 100, 1, 7991, 0))

with cue(7): note(1, 0.707, 200, gen_envelope(0, 8092, 1, 100, 0))

For the rest of the piece, it auto-cycles between a frequency pattern and an envelope pattern.

Best,

Jake

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

If that's of use, I can post some more of the code or create a more

Hope that helps!

Ah, I'm confused, as your original email had:

"Would one use tables for this? Not so elegant I think."

Yes, I should have had "(?)" at the end of that sentence! It seems that if python is doing all the dirty work then it doesn't look too bad! 

I'm playing with your ideas right now actually. The instrument design can get a bit messy but I'll write back in a bit. 

P

so I thought you were looking for options besides tables.  Anyways,
each of these things will have pluses and minuses.  For example, when
I work in Blue, I can start playback in the middle of a texture block.
Because it uses notes, I don't have to worry about rendering from the
beginning of the overall texture, I can just advance through the
score. Using tied notes also means possibilities for altering a
texture in realtime if you have an event generator sending notes to
Csound.  On the other hand, using an envelope as table can make the
instrument design simpler.  (I found Jake's code very easy to
understand and reason through.)  You might run into issues like the
duration of the note affecting the envelope rate, but you can also
work around that.

I guess the important thing though is that you have some options.
Also, you might consider mixing and matching possibilities.  For
example, a lot of the complexity of the instrument code I have has to
do with dealing with different scenarios on how the instrument is
called and the interaction with the orchestral composition library I
use from python/blue.  For your own instruments, you might simplify
things, but you could have an instrument that both responds to tied
notes, articulations, or use a negative articulation to denote an
ftable to read as an envelope.  That'd give you a lot of flexibility
then.

Here is another approach:

https://gist.github.com/jacobjoaquin/5413575

I feel I can reduce this example further, and when I do, I'll include it as an example case with PythonScore. In the meantime, here's the explanation of how it works.

Envelope shapes are generated as tables. They are created dynamically in score. Since we don't want tables overwriting tables as they're being played, I created the table_cycler that cycles through a range of table indexes every time a new table is created. In this case, the range is between 100 and 120.

table_cycler = cycle(xrange(100, 120))

The function that handles this is gen_envelope(). It takes a list of envelope points, and reformats it into a GEN07 "f" event. The args are the same as GEN07, but only the envelope data, as the first 5 "f" event pfields are automatically handled:

def gen_envelope(*args):

    global table_cycler

    table = table_cycler.next()

    L = ["f", table, score.cue.now(), 8192, -7] + list(args)

    score.write(" ".join(str(i) for i in L))

    return table

That function returns the number of the table generated. So a value between 100 and 120. If you watch the table numbers during a performance, you'll see it cycle through this range.

Now, one can pass an arbitrary number of envelope points. The first 5 notes in the score demo this explicitly:

with cue(0): note(4, 0.707, 1000, gen_envelope(0, 8092, 1, 100, 0))

with cue(4): note(1, 0.707, 700, gen_envelope(0, 100, 1, 8191, 0))

with cue(5): note(1, 0.707, 400, gen_envelope(1, 8192, 0))

with cue(6): note(1, 0.707, 100, gen_envelope(0, 100, 1, 100, 1, 7991, 0))

with cue(7): note(1, 0.707, 200, gen_envelope(0, 8092, 1, 100, 0))

For the rest of the piece, it auto-cycles between a frequency pattern and an envelope pattern.

Best,

Jake

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

I cleaned up the example and placed it with the PythonScore examples in the master branch of the CSD module:

https://github.com/jacobjoaquin/csd/blob/master/examples/PythonScore/multi_segment_env.csd

The plan is to create/collect lots of examples as a way to start identifying some of the design patterns that Python brings to the score environment. Once enough are collected and we have a sense of good ways of approaching common problems, functions and classes that reside in these examples we'll be pulled out, rewritten if necessary, and placed into modules that come with CSD. The examples will be updated in the process.

Here is another approach:

https://gist.github.com/jacobjoaquin/5413575

I feel I can reduce this example further, and when I do, I'll include it as an example case with PythonScore. In the meantime, here's the explanation of how it works.

Envelope shapes are generated as tables. They are created dynamically in score. Since we don't want tables overwriting tables as they're being played, I created the table_cycler that cycles through a range of table indexes every time a new table is created. In this case, the range is between 100 and 120.

table_cycler = cycle(xrange(100, 120))

The function that handles this is gen_envelope(). It takes a list of envelope points, and reformats it into a GEN07 "f" event. The args are the same as GEN07, but only the envelope data, as the first 5 "f" event pfields are automatically handled:

def gen_envelope(*args):

    global table_cycler

    table = table_cycler.next()

    L = ["f", table, score.cue.now(), 8192, -7] + list(args)

    score.write(" ".join(str(i) for i in L))

    return table

That function returns the number of the table generated. So a value between 100 and 120. If you watch the table numbers during a performance, you'll see it cycle through this range.

Now, one can pass an arbitrary number of envelope points. The first 5 notes in the score demo this explicitly:

with cue(0): note(4, 0.707, 1000, gen_envelope(0, 8092, 1, 100, 0))

with cue(4): note(1, 0.707, 700, gen_envelope(0, 100, 1, 8191, 0))

with cue(5): note(1, 0.707, 400, gen_envelope(1, 8192, 0))

with cue(6): note(1, 0.707, 100, gen_envelope(0, 100, 1, 100, 1, 7991, 0))

with cue(7): note(1, 0.707, 200, gen_envelope(0, 8092, 1, 100, 0))

For the rest of the piece, it auto-cycles between a frequency pattern and an envelope pattern.

Best,

Jake

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

Thanks, I haven't tried your example yet. That next! Here's my latest. Much more readable. I'm not so suave with python [yet!] so it's probably not the most efficient of doing it.

from csd.pysco import PythonScore
from random import choice

score = PythonScore()
cue = score.cue

score.write('f1 0 8192 10 1')

def note(p1, p2, p3, list):

    type = list.pop(1)

    if "l" in type:
        p7 = 1
    else:
        p7 = 0

    p4 = list.pop(0)
    linseg = list[0:]

    score.i(p1, p2, p3)
    paramName = '"' + p4+"."+str(p1) + '"'


    for i in range(len(linseg)-4):

        if i > 0:
            i = i+1
 
        t1 = linseg[i]
        v1 = linseg[i+1]
        t2 = linseg[i+2]
        v2 = linseg[i+3]

        start = t1
        dur = t2-t1
        point1 = v1
        point2 = v2

        score.i(2, start, dur,paramName, point1, point2, p7)
  

note(3.1, 0, 10, ["freq", "exp", 0, 1440, 1, 20, 1.3, 440])
note(3.2, 0, 10, ["freq", "lin", 0, 1440, 1, 200, 5, 1840])


score.end();

I cleaned up the example and placed it with the PythonScore examples in the master branch of the CSD module:

https://github.com/jacobjoaquin/csd/blob/master/examples/PythonScore/multi_segment_env.csd

The plan is to create/collect lots of examples as a way to start identifying some of the design patterns that Python brings to the score environment. Once enough are collected and we have a sense of good ways of approaching common problems, functions and classes that reside in these examples we'll be pulled out, rewritten if necessary, and placed into modules that come with CSD. The examples will be updated in the process.

Here is another approach:

https://gist.github.com/jacobjoaquin/5413575

I feel I can reduce this example further, and when I do, I'll include it as an example case with PythonScore. In the meantime, here's the explanation of how it works.

Envelope shapes are generated as tables. They are created dynamically in score. Since we don't want tables overwriting tables as they're being played, I created the table_cycler that cycles through a range of table indexes every time a new table is created. In this case, the range is between 100 and 120.

table_cycler = cycle(xrange(100, 120))

The function that handles this is gen_envelope(). It takes a list of envelope points, and reformats it into a GEN07 "f" event. The args are the same as GEN07, but only the envelope data, as the first 5 "f" event pfields are automatically handled:

def gen_envelope(*args):

    global table_cycler

    table = table_cycler.next()

    L = ["f", table, score.cue.now(), 8192, -7] + list(args)

    score.write(" ".join(str(i) for i in L))

    return table

That function returns the number of the table generated. So a value between 100 and 120. If you watch the table numbers during a performance, you'll see it cycle through this range.

Now, one can pass an arbitrary number of envelope points. The first 5 notes in the score demo this explicitly:

with cue(0): note(4, 0.707, 1000, gen_envelope(0, 8092, 1, 100, 0))

with cue(4): note(1, 0.707, 700, gen_envelope(0, 100, 1, 8191, 0))

with cue(5): note(1, 0.707, 400, gen_envelope(1, 8192, 0))

with cue(6): note(1, 0.707, 100, gen_envelope(0, 100, 1, 100, 1, 7991, 0))

with cue(7): note(1, 0.707, 200, gen_envelope(0, 8092, 1, 100, 0))

For the rest of the piece, it auto-cycles between a frequency pattern and an envelope pattern.

Best,

Jake

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

Thanks for posting these. I'm definitely reading and running them. Here's an supported featured debugging feature that might help, which will eventually be transformed into an official feature. To see what data is currently in the score object, do this:

for L in score.score_data:

    print L

I cleaned up the example and placed it with the PythonScore examples in the master branch of the CSD module:

https://github.com/jacobjoaquin/csd/blob/master/examples/PythonScore/multi_segment_env.csd

The plan is to create/collect lots of examples as a way to start identifying some of the design patterns that Python brings to the score environment. Once enough are collected and we have a sense of good ways of approaching common problems, functions and classes that reside in these examples we'll be pulled out, rewritten if necessary, and placed into modules that come with CSD. The examples will be updated in the process.

Here is another approach:

https://gist.github.com/jacobjoaquin/5413575

I feel I can reduce this example further, and when I do, I'll include it as an example case with PythonScore. In the meantime, here's the explanation of how it works.

Envelope shapes are generated as tables. They are created dynamically in score. Since we don't want tables overwriting tables as they're being played, I created the table_cycler that cycles through a range of table indexes every time a new table is created. In this case, the range is between 100 and 120.

table_cycler = cycle(xrange(100, 120))

The function that handles this is gen_envelope(). It takes a list of envelope points, and reformats it into a GEN07 "f" event. The args are the same as GEN07, but only the envelope data, as the first 5 "f" event pfields are automatically handled:

def gen_envelope(*args):

    global table_cycler

    table = table_cycler.next()

    L = ["f", table, score.cue.now(), 8192, -7] + list(args)

    score.write(" ".join(str(i) for i in L))

    return table

That function returns the number of the table generated. So a value between 100 and 120. If you watch the table numbers during a performance, you'll see it cycle through this range.

Now, one can pass an arbitrary number of envelope points. The first 5 notes in the score demo this explicitly:

with cue(0): note(4, 0.707, 1000, gen_envelope(0, 8092, 1, 100, 0))

with cue(4): note(1, 0.707, 700, gen_envelope(0, 100, 1, 8191, 0))

with cue(5): note(1, 0.707, 400, gen_envelope(1, 8192, 0))

with cue(6): note(1, 0.707, 100, gen_envelope(0, 100, 1, 100, 1, 7991, 0))

with cue(7): note(1, 0.707, 200, gen_envelope(0, 8092, 1, 100, 0))

For the rest of the piece, it auto-cycles between a frequency pattern and an envelope pattern.

Best,

Jake

I'll take a stab at this problem in a bit, but I'm hoping arrays in C6 will support something like the following. To solve the problem you presented, I think it would require two things. First, the ability to pass an as a pfield in the score:

i 1 0 4 440 0.5 array(0, 0.2, 1, 0.7, 1, 0.1, 0)

And then in the score, pass the array in as a list of args for opcodes:

ienvpoints getarray p6

kenv linseg *ienvpoints

There may need to be a third step required for scaling the even fields of the array, though is probably already supported by orchestra loop statements.

Thanks very much Steven,

I'm going to have a proper look at the code you posted. My initial impression is that this is possibly too convoluted for quick and dirty experimentation. I think it should be easier than that. Maybe with array in csound6 it will be possible?

Hi Peiman,

I've done a couple of ways using score generation:

1) For a limited number of articulations, I've added a pfield that is
used as an index to choose what envelope to generate

2) For arbitrary segments, I use fractional instrument numbers
together with tied-notes.  Essentially, each segment becomes a note.
Using fractional instr numbers allows for polyphonic streams.  I've
used this in pieces (you can check
blue/examples/pieces/stevenYi/etude/etude_part3.blue, the "StrA -
8.00" object) and am using this in my current piece to do group
glissandi sounds.

The setup for instruments for tied-notes can be a bit tricky, but I've
got a set of UDO's now that I use together as a template when building
instruments that will work with different p-fields given for a note.
That's allowed using an instrument with MIDI, by score with 5-fields,
or scores with 8-fields.  That in turn has made it nice to work with
live, for quick sketching, or for generation.

For example, code from my current piece uses:

def scoreFunc():
    end = [3,5,7][int(random.random() * 3)]

    ampGen = Mask(GaussRandom(),
         LinearSegment([(0,-20), (5,-14), (8.0, -14), (10,-50)]),
         LinearSegment([(0,-20), (5, -16),(8.0, -16), (10,-50)]))
    pchVarianceGen = Mask(GaussRandom(),
        LinearSegment([(0,.01), (4,7), (6,end)]),
        LinearSegment([(0,0), (4,3), (6,end -.09)]))

    return createUnstableGroup3(50, PchDeviation(8.00,pchVarianceGen), ampGen)

score = groupB64A.perform(scoreFunc)

The code uses a mix of PMask and some score generating functions to
generate a score performance func that groupB64A uses to generate
notes like:

If that's of use, I can post some more of the code or create a more
isolated example from my piece.

Hope that helps!

Hi Peiman,

Thought I'd mention, you may want to consider using formatting strings
[1] to modify:

    paramName = '"' + p4+"."+str(p1) + '"'

to:

    paramName = '"%s.%g"'%(p4, p1)

You may also want to use list slicing  [2] with multiple assignment
[2] to do something like this:

t1, v1, t2, v2 = linseg[i:i+4]

String formatting is good to know as you can get a lot of control
about the string formatting, and the template string can be easier to
use and understand, especially when using a lot of replacement values.
 List slicing and multiple assignment are also handy syntax sugar to
write more terser code.

Hope that's useful!
steven

Hi Peiman,

Thought I'd mention, you may want to consider using formatting strings
[1] to modify:

    paramName = '"' + p4+"."+str(p1) + '"'

to:

    paramName = '"%s.%g"'%(p4, p1)

You may also want to use list slicing  [2] with multiple assignment
[2] to do something like this:

t1, v1, t2, v2 = linseg[i:i+4]

String formatting is good to know as you can get a lot of control
about the string formatting, and the template string can be easier to
use and understand, especially when using a lot of replacement values.
 List slicing and multiple assignment are also handy syntax sugar to
write more terser code.

Hope that's useful!

In fact what I had was also stupid on so many other levels! This is the corrected one (attached). Also added amplitude automation.

Hi Peiman,

Thought I'd mention, you may want to consider using formatting strings
[1] to modify:

    paramName = '"' + p4+"."+str(p1) + '"'

to:

    paramName = '"%s.%g"'%(p4, p1)

You may also want to use list slicing  [2] with multiple assignment
[2] to do something like this:

t1, v1, t2, v2 = linseg[i:i+4]

String formatting is good to know as you can get a lot of control
about the string formatting, and the template string can be easier to
use and understand, especially when using a lot of replacement values.
 List slicing and multiple assignment are also handy syntax sugar to
write more terser code.

Hope that's useful!

BTW I'm totally a convert to python. What a beauty. I don't know what those SC3 people are doing! Honestly!

All I need to do now is to make the function into a class and the next time just write:

<CsScore bin="python">

from csd.pysco import PythonScore

score = PythonScore()

cue = score.cue

score.write('f1 0 32768 10 1')

with cue(0):

    score.i(3.1, 0, 10)

    parameter(3.1, "freq", "exp", [0, 1440, 1, 200, 2, 1000])

    parameter(3.1, "amp",  "exp", [0, 1, 1, 0.001, 2, 1, 10, 0.00001])

score.end();

</CsScore>

What's more, one could have as many 'parameters' as one wishes without defining any extra functions in python.

In fact what I had was also stupid on so many other levels! This is the corrected one (attached). Also added amplitude automation.

Hi Peiman,

Thought I'd mention, you may want to consider using formatting strings
[1] to modify:

    paramName = '"' + p4+"."+str(p1) + '"'

to:

    paramName = '"%s.%g"'%(p4, p1)

You may also want to use list slicing  [2] with multiple assignment
[2] to do something like this:

t1, v1, t2, v2 = linseg[i:i+4]

String formatting is good to know as you can get a lot of control
about the string formatting, and the template string can be easier to
use and understand, especially when using a lot of replacement values.
 List slicing and multiple assignment are also handy syntax sugar to
write more terser code.

Hope that's useful!
