Hi everyone.
I want to make a simple layout that will act exactly like expression ramper; an automated expression pedal so to say.
I want to use this with any pedal that accepts expression pedal to tinker around with its settings externally & automatically.
Expression ramper seems based on Atmega and digipot, but this can be achieved in a more simple way by using a basic LFO circuit. First of all, I'd need a basic full on / full off -you can call pulse- type of expression, with a rate pot indeed.
Has anyone made something like this before?
Before I forget, I'll feed this circuit with 9V, along with other pedals, and the output voltages to EXP should be between 0 to 5V (or 0 to 3.3v, I need to measure the pedals input)
