@musevg oh that needs a longer explanation, but the tl:dr is, that @todbot built a #MacroPadSynthPlug that adds a sound output feature to an adafruit numpad and I made a cheap version where I combined both.
Here's a thread on what I focused on while designing:

And then I got a broken casio keyboard and combined another key-test board thing with the LoKiPad here: https://chaos.social/@davedarko/109908178460110314
Attached: 2 images Having fun putting together a "ghetto" version of the adafruit macro pad, just because @[email protected] wrote such cool sound stuff for it. I want to recycle some components and this is fun to design till 3am apparently. I'm integrating his macro pad that uses the qwiic port for audio out and midi-in. Using up some simpler parts like 12mm buttons, 5mm neopixels and I might have ordered a 7-pin OLED display. On the back is a RP2040 PICO. Need to remove some through holes.
