This is the USB MIDI controller version of the Vintage Phone MIDI Controller.  As the USB MIDI support is much easier in CircuitPython than MicroPython, this is also a version of the keypad controller code for CircuitPython too. Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for … Continue reading Vintage Phone USB MIDI Controller

Warning! I strongly recommend using old or second hand equipment for your experiments.  I am not responsible for any … Continue reading Arduino MIDI 7 Segment Controller – Part 2
