Anything with more than one oscillator is polyphonic. :-)
I tuned four PCOs to the just intonated chords, controlled from a 4x8
sequencer. These four oscillators were mixed, then sent through the same
filters and ring modulator. I had another two PCOs tuned from two rows of
a TKB which went through another filter/amplifier patch.
You don't necessarily need an oscillator-filter-amplifier patch per voice
for polyphonic synthesis. This is one of the benefits of modulars: it
breaks you out from thinking in the same old mold.
Since the TKB is freely tunable, it is one of the few analog controllers
good for just intonation. Any non-quantized analog sequencer can do just
intonation. Most step sequencers like the Serge's have real analog control.
All pattern based sequencers are digital to analog converter based and are
naturally quantized, ruling out just intonation as a possibility. This
includes the models from Doepfer, Future Retro, etc.
