I don’t have a Eurorack but interested in Misha only for MIDI setup with my hardware synths. Will it work with only a +12V and GND setup? Or do I need -12V too? I am trying to figure out a custom case for it. I saw the compact 4ms case in the previous thread but that’s still pretty steep and I have lots of 12V PSUs.
Misha uses a standard Eurorack power supply, so the -12V rail is necessary. If you are building a custom case, you would also need to look into adding a Eurorack power supply to your case. The 4MS option is your best bet and is a good price considering it comes with the necessary power supply.
