What operating system/libraries/etc. do you use? We use Linux. Debian or Knoppix to be specific. Most of the code is written in Python, except for the low-level tracking code, which is in C and C++. We use the Pysco optimizer to speed up the Python. We use OpenGL for graphics, and talk to the synthesizer using MIDI. http://web.media.mit.edu/~jpatten/apad/apfaq.html Cheers Daniel
