I’ve been using my Pyramid with an Endorphin.es Shuttle Control to great success. I’m having a big issue that Endorphin.es has not been terribly helpful with.
Depending on the pads that are lit up, I’m getting a constant tone of about 247 hz (B3) coming from some of my modules. Shuttle Control shouldn’t be dumping that digital noise into the power bus, but the Shuttle Control should also not be causing that. Do I have a defective unit? Powering externally isn’t an option and I’m WELL within the specs of this Trogotronic m15 PSU.
Here’s a short video I did for Endorphin.es: https://photos.app.goo.gl/37Z2BBgH07kFAY0i1
Endorphin.es thinks it’s a ground loop, so I’ll be exploring options for reducing it.
