Thanks for that. I found and futzed with that Python approach last night for a couple of hours and was unable to sort out the syntax and failed to get it to run. I kept getting "Syntax" errors. LOL!

I've a bit more reading to do.

I got one of those cheap Chinese 24x EEPROM burner/readers and I use it with SpinCAD Designer, SpinASM and a Spin-Semi FV-1 Development board to help jockey and identify the different FV-1 algorithms. The challenge is keeping them all organized.I've got a bunch of those EEPROMs loaded with programs.....but they all got mixed together so I have no clue which programs are on what chip. It's kind of cool though....pop in a chip and it selects your mood.
Years ago I built a discrete logic version of a Shepard Function Generator to drive 8 VCFs and 8 VCAs to develop a barber-pole filter. Ever since, I've been looking for an means to do it with an FV-1. When Mr Black came out with his "Shepard's End" pedal, I found out it was an FV-1 based pedal. So I bought one to check it out. Sure enough, it does a wonderful job of thru-zero flanging in barber-pole fashion. I'm still wrestling with the code on that one after getting the algorithm converted/disassembled to SpinASM. The hard part is re-creating it in SpinCAD Designer. Just having the code is one thing, but to understand it visually with SpinCAD Designer (for me) is a whole other dimension. I'm just a GUI type of fellow.

It seems to come and go at random days/intervals. Sometimes the site launches and other times (my best guess) it's just offline.

I have no idea how he does a Shepard flanger, but were I to attempt such a thing I'd start with:
2 servo flangers with synchronized LFOs. This might be a bit tough because the LFO probably wants to be a ramp to go linearly from 0 to 1 (or vice versa) and then snap back to the other end. And right before you do that, you'd want to fade to the other flanger which was just starting to go up. I say it's tough because you're going to want to use the "Servo Flanger" rather than a sine LFO and each one uses one of the 2 built-in RAMP LFOs.
