This is a short demonstration showing an 8-way Raspberry Pi V1 MiniDexed system.

The main Pi has the UI and the first tone generator. TGs 2 to 7 come from 7 additional Pi V1 boards each with their own audio output. TGs are available on MIDI channels 1 to 8 and the video shows Pachabel's Canon in D playing across MIDI channels 2 to 7 initially all using the default Brass 1 MiniDexed sound but the main Pi V1 is used to change the voice on all TGs as the tune plays.

Yes it is pointless. Yes, this is the equivalent of a single Pi 3 running MiniDexed. But I also like to reuse a Pi V1 here and there just to see if I can because... well, why not?
