Hi
This is my first post here.
I recently discovered AE Modular and the possibilities of the DIY part of it. I don't have my system yet as I still have to wait for my February pay check. But I'm already looking into the DIY, or more specifically DIY modules that use Arduino or other MCU boards as I'm an third year IT student and MCU programming is easy (and fun) for me.
So I found a Chord VCO module on Youtube that was originally designed for Eurorack. But it sounds so good that I'm willing to go through hell to make it work with AE Modular. Here is the link to the video.
For those who don't want to watch the whole video, here is the Schematic for it:
So here come the questions I need help with. First, I need to change the Op-Amp IC. If i understand correctly in need a Single power supply, Rail to rail Op-Amp, correct me if I'm wrong. If anybody knows such IC (possibly quad Op-Amp IC) that would give good sound quality then please tell me.
Second, I'm not sure if I need those BAT43 diodes, if I'm correct they are there for some over voltage protection or something like that, but as AE Modular's voltage levels don't go over 5V then they are not needed, right? Third, if I don't need the diodes (also I can't find any seller that has them, the designer is from Japan, so i assume he uses some Japan only parts) then how would the schematic look like after? My Electronics skills are not the best, so try to explain it so i could understand.
With regards
