Hello, Stefan,
Iain is correct (he always is, and you can totally count
on his advice regarding realtime). My bad. *Controller* 64 is the foot
controller/switch for MIDI.
Suggestions:
Delete line 14 *as well as 13*.
In instrument 2, substitute:
gkpedal ctrl7 2, 64, 0, 1
Then play your keyboard on channel 1, but put the foot
controller on channel 2. (Alternately, put the foot controller on any channel
except #1; number the instrument the same as the channel and give the controller
the same number also (e.g., gkpedal ctrl7 10 for channel 10).) This should send
all keyboard data to instr 1, pedal data to instr 2.
Frankly, I've always had trouble getting insnum to trigger
notes, and never use it. If the above doesn't work, I'd try another approach:
use an always-on instrument 1 that handles *all* midi input; when noteon's are
received, it schedules events (through event or schedkwhen) for instrument
2. Working at k-rate, it also handles pedal-data (as in your i2).
All of my live performance works use this principle; you
can look at many .csd's at my website, arthunkins.com, if you'd
like.
Let us know how you get on.

Hi Stefan
massign 64, 2
You are assigning MIDI
note events on channel 64 to instr 2; but MIDI channels only go from 1-16 (or
0-15).
Bye,
Iain

Dear Art,
thanks for Your anwer.
I guess I changed
something in my file, but I dont know what.
Now I get the following error
message:
INIT ERROR in instr 0: ? [illegal channel number? [m
?[m
massign 64, 2
When I erase the line number 14 in the file, I can hear a
sound, but I can't, off course, change any pitch. What I don't understand is:
Is it right, that 64 should be a number of controller, not of a
channel?
If so, how can I tell csound this?
Here is, again, the whole
file, without german comments.
Thank You very
much,
Stefan

Stefan,
Please tell us which lines are #30 and #31, and
what the specific error messages are.
If any German commentary is involved, please
translate for me; ich verstehe deutsch nicht so gut.
I do see one error:
icps =
(ipedal > 0? icps - (icps * .9): icps + (icps * .1))
(This may
be the problem - or one of them.)

Hello, Stefan,
Here's what I'd try:
In header:
gkpedal init 0
and after your massign:
massign 64, 2
(or whatever controller # your foot pedal
is, assign its data to instr 2. The massigns may be
tricky.)
You should be able to use any type of foot
pedal your MIDI keyboard will accept.
Make a completely new instrument that
receives MIDI data only on controller 64 (or whichever # you
choose):
instr 2
gkpedal ctrl7 1, 64, 0, 1
endin
The above instrument is always receiving
foot controller data.
In the score, add:
i2 0 3600
In your instr1, add (at
beginning):
ipedal = i(gkpedal)
and later (after icps
computed):
if imnn != 60 and imnn != 62 and
notnum ...... igoto skip ; this is a list of *all your black MIDI key
numbers*!
icps = (ipedal > 0? icps - (icps * .1):
icps + (icps * .1)
skip:
In the above, ".1" is the percentage of the
frequency you wish to add or subtract from your "basic pitch"
(12tet).
You may want to make some other kind of
pitch adjustment. For example you might put the low version (freq) of
the black key pitch in your table, then multiply it by some factor if
the pedal were up (gkpedal == 0):
icps = (ipedal > 0? icps + (icps * .1):
icps)
Or perhaps you want different groups of
"igoto" branches, where for example all F#'s modify in one way, all G#'s
in another.
Let me know how it works out for
you.

Subject: [Csnd] Re: Re: different
pitches during a live-midi performance
Dear Art, thanks for Your answer. I have attached a
small example to this mail. I use there a scale with 17 pitches per
octave but (as You all know)I do have only 12 pitches per octave on
the keyboard. I would like to allocate the black key two pitches
and I would like to change this with the pressure of the
una-corda-pedal (the left pedal). While pressing the left pedal down,
I would like to get a lower pitch, in the other case, the higher
pitch. But I have no idea, how to do it with csound. So, I really
need Your help! At least I hope, that my idea of negotiating the
limitation of 12 pitches per octave in this way will be interesting
for other musicians to. Thanks Stefan :
2009/7/2 Art Hunkins <abhunkin@uncg.edu>
Yes, certainly. But tell us more what
you have in mind.
I assume your keyboard would be a MIDI
controller, correct?
An obvious choice would be a MIDI foot
controller input through the keyboard, or a MIDI footswitch in
conjunction with a foot controller or a portamento
pedal.
If you need specific pitches from the
pedal(s) - even from a standalone portamento pedal, Csound could
"round" the pedal to the nearest pitch, or indeed add a rounded
percentage to the current keyboard pitch.
There are many
possibilities.

Subject: [Csnd] different
pitches during a live-midi performance
Dear community,
I want to know, if it could be
possible, to get different pitches for e.g. fis and ges during a
live-midi performance.
What I desire, is to influence the pitch
by a controller, e.g. the left piano-pedal.
I'm not speaking of
pitch-bending, I really mean an exact, clearly regognizable pitch,
when You press a key with od without this controller.
Is it
possible?
