They are identical except for frequency range.
It's a "self-playing" patch, using an LFO as a trigger for the envelope generator.
Thank you SO much for this plugin. There are far too few software "analog" modulars around, and even fewer with "free-running" oscillators (not requiring external note input via MIDI, on-screen keyboard or what have you).
All the better that this one is free, very lightweight, and only requires a VST host.
Oh, and it sounds AWESOME.
If I had one "enhancement request", it would be for an OSX version (my primary platform is a MacBook Pro
).
