I can buy a Doepfer Dark Link USB/MIDI to CV/Gate Interface for under $200. I was hoping/assuming that functionality would be built into this controller. This is a modern digital device. The keyboard on my SH-5 is basically just a long copper ribbon and voltage changes depending on where along the ribbon you create a short. With a modern keyboard you’re controlling software/firmware as soon as you touch anything. Now, it may be that the design, by some unfortunate oversight, prohibits external midi note on/off passing to the cv/gate. Have you seen the schematics? Is there a software developer kit available? I spent most of my career designing recording equipment, now I just play. If it’s possible, I can make it work and I’ll be happy to share. Or I’ll just, sigh, go ahead and buy a Doepfer.
