Doepfer

Hi.I had the same questions a couple of years ago . I ended up buying the Analogue Systems 
RS370 Polyphonic harmonic generator. I mainly use A100 modules but this is a great module 
that sounds amazing running through doepfer filters. You can get beautifully rich and mello 
pads if you detune the 6 different voices and nasty edgy pads if you run it trough a Wasp 
filter. There is an expander to change the harmonics in real time but this only works if you 
are in Mono mode.
