I have one of these:

... and a couple of STM32 Discovery boards, which have a built-in ST-Link adaptor. I've written some synthesis stuff on them.

I reckon the faster ones might be able to do 8-note poly and have an 8-way multiplexer on their outputs, to get separate audio channels. This wouldn't be such a biggie for our Poly 800s with a single filter, but might be useful on more complex machines.

Of course you could just mix all your polyphonic wavetable voices into a single channel (and have digital filters for each voice, they're easy to do) and stick the single output through the Poly 800's filter IC...
