Hi Matt,

I listened with great curiosity the example: C + C interactive computer
music (2006-07) http://mattingalls.com/mp3/ma++ingalls_C+C.mp3 that appears
on your website at [http:/ / mattingalls.com / electronic_works.html], I am
pleased with the result and I am very curious to learn more about the
program you wrote interaction with MacCsound.

It 'can get information about the patch, or maybe you can see the overall
structure of the algorithm that you wrote in order to understand better the
functioning?

Many thanks,

e

here's how the patch is presented by Matt Ingalls:

"An interactive computer program i wrote in MacCsound that "improvises" with
me. Intended as "CLAIRE 2.0" (see below) of sorts, the program listens to my
clarinet playing via a microphone and analyzes the input to determine
what/where/when to sound its sample-based output. There are no explicit
controls - the only way i can influence the computer's output is through my
own playing."

I'm looking for similar experiences made by the community Csound for live
electronics (or MacCsound QuteCsound).

thanks,

e

Off the top of my head I can think of pieces by Iain, Oeyvind,
Matt(obviously), Richard Boulanger, and Victor that all call for live
'electronics' in Csound. There's little that can't be done in
real-time these days. If you are new to doing live pieces the first
thing I'd advise you to do is free yourself of mouse clicks and start
using some controllers. Csound can handle pretty much any controller
out there.

Rory.

... you can see some csd written for the live-electronics?

thanks,

e

You can have a look at this one. It's pretty rough but I've used it
and variations of it several times for live performance. The reason
why live instruments don't tend to 'travel' well is that most people
set up their live instruments based on the controllers they use. Some
of my pieces call for up to 9 faders, 16 or so pan-pots and perhaps a
dozen buttons. In order to get the attached file to work you will need
to rewrite the MIDI code so that it matches your controller.

Rory.

Thanks Rory!

I will study your csd.

I'd love a patch to handle the signal coming from the microphone.
A little 'as Matt said above: 
"An interactive computer program i wrote in MacCsound that "improvises" with
me. Intended as "CLAIRE 2.0" (see below) of sorts, the program listens to my
clarinet playing via a microphone and analyzes the input to determine
what/where/when to sound its sample-based output. There are no explicit
controls - the only way i can influence the computer's output is through my
own playing."

And then ...

• How system call (call) to trigger other instruments (Called) I think the
pitch, I think the scale, I think the delay lines, but my choice of options
for now all ...

• I also think what they could do the instruments called (Called), but my
imagination has run out ...

???

What you want to do is relatively straightforward. Just use one of the
pitch tracking opcodes to get the frequency of the incoming signal.
After that you can use an event opcode to trigger any other
effects/instrument.

…this is my little idea about the use of thresholds pitch to turn something
(attached).
It could be a starting point?

From looking at the code it seems like a reasonable starting point.
Keep experimenting. You'll find some pitch tracker work better for
certain tasks than other.

hi jpff
fantastic! very nice!

thanks a lot,

e

wav file attached to my test:

e
http://csound.1045644.n5.nabble.com/file/n3331025/test4.wav test4.wav 

Hi Matt, 

I listened with great curiosity the example: C + C interactive computer
music (2006-07) http://mattingalls.com/mp3/ma++ingalls_C+C.mp3 that appears
on your website at [http:/ / mattingalls.com / electronic_works.html], I am
pleased with the result and I am very curious to learn more about the
program you wrote interaction with MacCsound. 

It 'can get information about the patch, or maybe you can see the overall
structure of the algorithm that you wrote in order to understand better the
functioning? 

Many thanks, 

e

hi enrico

sorry i missed the whole discussion about this in january.

thanks for your interest!  

i should first come clean and say the last half of the piece is a pure tape part.
which i really like for it's practicality and also raises some philosophical/aesthetic
issues (what is the difference between playing a 1 sec sample or a 1 min sample?
 or a 10min "tape piece" for that matter?)

but if you are interested in the first part of the piece, i will try to explain it here.

my approach comes from george lewis -- you should check out
his "voyager" if you haven't already

the basic structure fairly straight-forward. 
multiple "always on" instruments - each one for a different task:

+ Input: a 'pitch' opcode and logic to determine note on/offs, write to buffer
  (i know i tried all the pitch-tracking opcodes and this one was the best one for
    me accuracy & cpu )

+ Analysis: averages & limits of input 

+ Play: spawns "events" (instrument playing pre-sampled sounds from my own playing)
     has different "modes" of playing based on analysis and lots of random numbers
    i add more 'play' instruments as the piece progresses

+ then a couple gimmicks - silence, long tones, and a "tape part" that is the last 
1/2 of the piece!

one thing that i came away with after doing this piece is that if i wanted to this thing again
i would strip out all the logic/algorithmic stuff and do it in C -  a visual debugger 
and being able to step through code, set breakpoints, and view current variable
values makes life so much easier it is worth the extra hassle of hosting a CsoundLib
or a separate application sending MIDI messages to Csound or whatever.  
( or just not even use Csound? )

i'm attaching the .csd here - (i'm not sure if that will help any -- i don't even understand it anymore!)
the csound code was expanded after this recording, i added some new gestures to the computer part - 
but i dont have a good document of it, unfortunately.

thanks matt
I will study carefully your csd

e

Hi Matt

I tested the instr "Input" and say that the code is very complex...
I have written a flow chart to understand.

You can tell me what are the functions of the instrument "Input "?

thanks
e

> 
> I have written a flow chart to understand.

i'd like to see that!!

> 
> You can tell me what are the functions of the instrument "Input "?

mostly determines if a new "note" has started and/or current "note" has ended.
since what we hear as one of those can either be a change in pitch or in amplitude,
there is some logic needed to determine that.

and at same time, i keep track of duration of note and time between the last note
started and the current note started (which i call "density")

when the note ends, i then write its info (pitch, dur, amp, density) to a table 
to be used in the "analysis" instrument.

Hi Matt,

the first part of the flow chart you can see in my previous message.
…Maybe you have trouble viewing the image file. jpeg?
I think I rewrite in "fair copy" that diagram ...

Thanks for the additional guidance,

Matt,

this part of the orchestra (instr make and instr RotateTable) is autonomous?
…is a "special couple gimmicks"?

if so I ask:
- aif file for how long are they?
- how the files are used with loscil opcode?

thanks
