I have been playing the supernova II by novation since 2000 mostly as often as I can.  I have worked with the presets reprogramming over 1/2 of the over 500 presets -- each preset has 8 patches - each patch has almost an endless set of settings that can be adjusted during play or set and saved into their own settings. there are 10 sets of 128 patches to be added to each of the 4 sets of 128 performance settings 8 at a time.
