Hello Folks,
I want to build a single expression pedal that can control at least three different effect pedals. They are all expecting a TRS connection and a 10k pot works on all the three devices. I measured the voltage they are sending through the TRS cable and they are all close, but different:
Eventide H9: 2,12V
Strymon El Capistan: 3,3V
EHX Pitch Fork: 2,96V
Is possible to connect the output of my expression pedal in to the Analog Pin input from Teensy, read the values, translate to all the three expected Voltage and then send through three different Analog Pin outputs to the effect pedals? How about the ground? Can I use the Teensy ground here?
It does make sense, right? Or I will need to use a Digital Pot?
Is the principle of this device: https://missionengineering.com/shop.../multi-use-exp/expressionator/?v=3a52f3c22ed6
I really appreciate any help!
Thank you!
Cheers!
