The MTSeq is a multitouch enabled music generation and manipulation system. It consists of a CHR based music generator engine, the audio processing application "bidule" as a backend and an exclusively designed GUI with a set of multitouch- and gesture-enabled widgets. The system is able to generate a piece of music with the given parameters and allows the user to manipulate this music in realtime with a multitouch-controllable audio effects stack.
The system was also described in an application paper for the CHR workshop 2010 at FLoC conference, Edinburgh. See details here: http://www.uni-ulm.de/in/pm/forschung/themen/chr/info/downloads.html
