Cgs synth

Yes, the signal being fed into your CGS26 won't be processed per se--it'll be
raw voltage waveforms directly from the transducers--but it definitely has a
shape that is later processed by the brain and formed into a MIDI envelope.

I'll order a CGS26 right away and start tinkering. This could solve a huge
problem for electronic drummers, as current e-drum technology doesn't simulate
snare drum or hi-hat behavior very well at all. It changes the way we play in
ways that don't translate over to a real drumset.

Thanks, Ken!

Oh, so the drum triggers are a processed waveform containing velocity and
perhaps some sort of envelope?
In that case the CGS26 may do what you want.
