yeah I’ve always been curious about them and was after one pretty hard for about a year. tough to find one that’s in good shape that isn’t insanely expensive!
do you have an A4 or AK? the poly mode in those with some of the voice assignment options can do some pretty interesting Mono/Poly style stuff. arpeggiator or chords looping through the voices, for example. or unison mode to trigger all of them. it’s not quite the same, but it’s actually deeper and more powerful in other ways. mainly because the voices can be totally different and they’re each a complete voice (their own settings for osc’s, filters, lfo’s, amp, etc) versus sharing filter/amp/lfo’s/etc. it’s nowhere near as fun or immediate to edit the sounds though!
