How to use a NOPE with EHX superswitcher/ Boss ES-8 and alike control outputs

There have been a few of these questions during the last months.
So here is what you can do if you want to use a NoPe switch at the control outputs of an ES-8 or superswich or whatever unit is out there that hav 5V control signals to be programmed.

Also if your control unit does not put out control signals and instead uses a switch its easy as one side of the switch needs +5V from the circuit and the other one then connects to the input of the NoPe.

There is an electronically good and a bad solution (of course the bad one is faster to achieve) but we focus on the “good” one here.

This is what you need to do:

  • Remove C1
  • Replace R3 (10k) with 100k
  • Replace R1 (68k) with 1k
  • lift (cut off) pin 3 of IC1
  • Connect GND of controller to GND of Nope
  • Connect Control of Controller to SW. (mind the dot!)  its the pad next to C3
