I pronounce the Synthasystem fully resurrected. The last module was the Ring Modulator. Nyle spent a couple of hours with me today and it works. I can now make the order for a small production run of the last three PCBs. The panels are done and now I'm going to build my modules.
I'll update the web pages over the next few days and get the module information up to date.
Technically, I suppose I have to do a keyboard, but for all practical purposes, the Synthasystem modules are all done and tested.
Keep watching for more videos, build photos, etc.
