I wanted to do a project where the many people could contribute to a big Max patch for treating audio. So I developed Framework, a free to use / modify modular audio patch made in Max/MSP. Download it from the download section of my site http://leafcutter.33-rpm.net
, read the info and get coding! (note: you need to have a copy of Max/Msp 4.5+ to make modules!)
The framework part of the patch comprises 9 bpatcher objects connected in series (using scripting). The user loads different kind of audio treatment modules into the bpatchers.
You play a stereo file into the framework using splay~~. Or you can use a mic input. If you want to do something different to this then please hack the patch!
Make your own modules and submit them via email for inclusion in the next release of Framework.
