generative audio

Im currently in the middle of a project where i need to use jitter information to generate audio. I have a patch at the moment that ive set up to track red green and blue objects seperately. This works to a certain extent but is only outputting random midi notes or cycle frequencies. The aim is to get the audio to be more structured and for the patch to act as a sound track generator.

Any help would be much appreciated.

Few suggestions that maybe useful,

try the {scale} object to scale say incoming matrix data like 0 255 (colour) to 48-72 (2 octave range), also maybe the speedlim object as it only outputs data at a certain interval that can be set by the user, it quite useful as jitter matrices kick out a lot of data quickly!

Also what i have done in thing similar situations is create objects that only allow midi notes in a certain key to play, try using {select} for this.

if you stuck give me a shout and i can dig something out that you might find useful,

– Pasted Max Patch, click to expand. –

Thats the sub patch im using to create the sound. I think the problem might be that its using the coordinates of objects that are tracked by colour to produce the midi notes. I basically want it to use only colour data to produce the sound instead of the coordinates of objects in the video.
I would upload the full patch to let you see whats happening but it wont let me upload video.

Thanks again for the help.
