korg poly-800:

4 or 8 voices (1 or 2 DCOs/voice)
 -> 1 DCA/voice (1 or 2 EGs)
 -> 1 DCF 24dB/oct all 8 voices
 -> stereo effects

The filter is after the DCAs... -pc

I would think that you could have multiple oscillators, each getting its own CV, feed them into a mixer, then from there to filtering etc.  Any thoughts are greatly appreciated!
