Alternative PCB for Pythagoras circuit at PCBWay.com

30 positions won't work. The FV-1 requires 8 or less.
It's got 5 pins, and a push switch so 2 of those are for the switch. This leaves 3, which I assume are 2 quadrature outs and the common. You'd have to add logic or something like a PIC to that to get a parallel digital output. I assume the 30 position are the detents. I could be wrong of course, be nicer to have the actual mfr spec, but I wouldn't start with this in any case.

As I said at the time, that can be used if you add all the diodes of the original schematic. Order the board from pedal PCB and use that, not my board. Or hand-wire in the diodes on the switch. We're going around in circles.
We ordered your card, it has not arrived yet, I will add the diodes as you said, thank you also for your card, best regards.
 
Use what ever you want.
Hello, your PCB board works great, thank you very much. I have a question. Currently, I'm using the built-in effects, and I'm experiencing a 1-second delay with the pitch shifter effect, which many people dislike. How can I fix this? If I load different effects onto the EEPROM chip, will the pitch shifter effect also create the same problem? How can I overcome this issue?

The EEPROM chip is an external source of FV-1 patches (algorithms) and does not interact with the internal patches of the FV-1 in any way. The internal patches cannot be changed - except to transfer them to an EEPROM , from which they can then be extracted, massaged & edited and then placed back onto an EEPROM for reading by the FV-1 as an external source.

I understand. So, I'd like to ask this question: To prevent or reduce the audio delay at the input, can a buffer circuit be added to or before the output of the FV-1 pedal? I only experience the delay (audio lagging behind) in pitch shifter mode; this is a common problem even with many branded pedals. Also, if we want to use the pitch shifter from EEPROM memory, I assume this delay can be resolved via software. Is this correct? If so, what kind of intervention would be necessary? Thanks.

No. Pitch-Shifting is where the FV-1 falls short. It does not possess the processing power to conduct Pitch-Shifting without added latency.
