Rock Hardbuns has released an updated version of Padpal 3, a free instrument plug-in for Windows.
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.
The update fixes a bug with buffers not being emptied. This could cause hanging ringing sounds in Ableton Live.
Padpal 3 is available as a freeware VST instrument for Windows PC.
