873Re: Portamento Spreads the Voices
- Apr 21, 2013In trying to answer my own question regarding voice-spreading portamento on other synths, check out this link discussing the Oberheim OB-X analog polysynth:
If you skip down quite a bit (~2/3rds of the way), he talks about using the synth in Unison mode, which reveals the OB-X's imperfections in its polyphonic glide, which causes different glide rates for each voice. Hey! This is just like what I had discovered about the Mono/Poly! He is clearly in love with this sound, just like me.
Based on his text, though, it does not appear that the circuit for the OB-X was *purposely* designed to spread the voices -- it doesn't sound like Oberheim was purposely trying to have the glide rates be different, they just turned out that way. So, the purposely-detuned portamento in the Mono/Poly could still be a unique feature to itself.
What other synths have multi-voice glide? Are the invidual glide rates purposely different from each other?

So, I did some analysis of the Portamento on the Mono/Poly and found that it purposely spreads the pitches of the individual voices to make the sound more interesting and exciting.
