I absolutely love the sound of the Baja Trembulator, so what better project to start with when it’s time to try the tap-tempo LFO micro controller?


This is a very basic adaptation; just the signal part of the Trembulator with the standard LFO circuit replaced with the micro controller (and associated components).

I kept all the multipliers, but didn’t really care for the ramp waves, and the triangle wave was very similar to the sine wave, so I decided to keep only the sine- and square wave settings.


I did try this on breadboard, so I’m fairly confident it’ll work. Will update once I’ve built it.

And if you can’t figure out how to compile and program the uC I’ll consider setting a few up and ship out for cost (depending on demand etc.)
