FV-1 Development PCB Program change ?

[Kastor]

Hello


I am done with the planning of my midification of the Arachnoid MultiFX. But now I saw the FV-1 Devboard.
Ofc it looks interesting, since I could easily push my own programs.

How can I change the program with that board ? Or is it set to program 1 ?
Also I use PWN to send the voltage for the parameters (0-3.3v) to the POT pins. can I just connect the PWM Output to the middle whole of the top potis ?

I attached my idea so far.
When a Midi program change is sent or the Preset knob is used to select a preset.
The Program change is sent to S0, S1 and S2. And the parameter values set.

I also wanted to add the EEPROM on the Arachnoid to the Arduino, so I could write it from there but, the Devboard already has that.
So my question is can I hook in like I would to the Arachnoid board ?

The FV-1 Dev board uses a 3 way toggle switch to select programs (similar to the Pythagoras), but S2 is grounded so you wouldn't be able to pull it high without either lifting the pin of the FV-1 or cutting the ground pour around that pad on the PCB.

Aside from that, yes, you can connect a filtered PWM output directly to lug 2 of each control pot.

Ok, thanks for the info !

Then I stick to the Arachnoid PCB, and must get creative
