Hi guys and gals, I was getting into the Fv-1 and would like to try to give this design a go myself with a few alterations which you may be of help. There's this website www.electro-smith.com/electro-boards/fv-1-dsp which provides the fv-1 basically as I want it. My idea is to buy 2 or 3 of them so I can chain them together. Basically I want to be able to set the fx route like: 1 > 2 > 3, or like: 2 > 1 > 3. This way it kind of replicates the way the old Yamaha samplers use their multi fxs, which I'm a huge fan of. As I'm not suuuuuuuuuper into electronics, but trying to wrap my head around, I've a couple of (easy) questions. 1. Would the pcb like this be necessary of any additional components besides the usual pots, leds, etc? It doesn't seems like it, but yea you know... :-). 2. The control inputs seem to be 0v - 3.3v, would this be easily as attaching a resistor/zenerdiode so the output of, let's say the AE modular, won't exceed over the 3.3v limit? 3. Any of you have any creative ideas how I can make a switch to set this fx route previously explained? Hope you guys can help me out on this one and help me make this sick 3 part multifx module/pedal

Actually, you're a lot closer to this being real than you might think, given that the MULTIFX module is already Spin FX-1 based.

I'm aware of that ! The thing is, that I would like to flash my own preset designs to it. Next to that, It would be nice to have it in pedal format (with cv if possible) instead of the AE format. Nevertheless, the MultiFX is in top 3 of my GAS list :').

Well found some extra info about replacing the potmeters with cv inputs, but curious if this also works with potentiometers still in there. It should. When modifying for this, make sure to use switching jacks or some way to switch between the internal CVs and the injected ones. Then make sure these CV insert points are upstream from the pots, which will then allow you to use the pots as trimmers for the incoming CVs as well as the internal ones when nothing's connected.

Would you recommend to use diodes or resistors to feed the FV-1 parameters with AE modules? Not sure if the current spikes may damage the FV-1 pcb...

Well, it's done! No CV inputs (yet), but couldn't wait to start this thing. Actually pretty doable build :-). Attachments:
