Updated Sep 20th 2009: Fixed bug with buffers not being emptied. If you got hanging ringing sounds in Abelton Live, try it now.

Improved version of my PAD synth, sporting brand new impulse/filter envelopes. Its not entirely obvious how it works but you can read all about it here:
http://zynaddsubfx.sourceforge.net/doc/PADsynth/PADsynth.htm

My implementation (as opposed to Zynaddsubfx's) uses buttons for the partials. The buttons cycle from Off, to 25% to 100% and then back to off.

It only has 8 presets. Maybe I'll make more later on.
