Unison mode

Looks like, e.g., the Korg opsix has a Unison mode, where you set up one voice, and then just enable Unison with three parameters:

• How many voices to use (2...8),

• Spread (how much Stereo Pan to use),

• Detune (how large the overall range for is for Detune across all voices).

• See the Unison, Detune, Spread sections in the Korg opsix manual.

WIth more powerful Raspberry Pis, maybe we can have more than just 8 voices in total? 8 TGs wich can have Unison would theoretically give us up to 64...

"Additional Parameters (ACED Format)" in the Yamaha DX7 II D Supplement Booklet specifies the parameter the DXII uses for Unison, especially PMOD (unison off/on) and UDTN (unison detune depth). No way to set the number of unison voices and the amount of stereo panning?

This is how it worked in in the DX II D:

Maybe this is too rigid for today's use?

fwiw, the Korg opsix native VSTi also implements this as described in the original post. Makes a big difference for many sounds!
