[sdiy] Some Synergy info, was Re: Synclavier

As well as the Synergy emulation mode, I wanted to add other features, like filter emulation (directly applying scalars to each operator according to some sort of response map is what had in mind here). The actual core is a handful of accumulates and a couple of table lookups. The Synergy did the look ups by holding a table of values and slopes so the interpolation was quick. This allowed them to generate better than 8 bit sines from 8 bit data. My plan was to move this to an FPGA at some point too.

It may be easiest to follow in the footsteps of Herman Sieb's PPG Wave simulation.  That way there's nothing to invent, only copy.  And the hardware's pretty simple and well documented, isn't it?  Someone's got to have a Kaypro emulator out there that could be used to interface with it, right?  Of course it's going to have all the limitations and crappy interface as the original, but the original did have some pretty clever stuff already that hasn't made its way into anything more modern.  I think a lot of people (me, anyway) would almost find that more interesting than the synth engine itself.
