Usage
Connect the PropMaker Feather RP2040 to your computer with a USB C cable. Then, open up your DAW or other software that supports MIDI out.
USB MIDI Device
The Feather RP2040 Prop-Maker will show up as a USB MIDI device on your computer. It features a USB MIDI port appropriately named CircuitPython usb_midi.
External MIDI Device
In your DAW software, an external MIDI instrument will allow you to choose the Feather RP2040 Prop-Maker as the destination on all MIDI channels. You'll use this track to output the MIDI notes from a MIDI controller or piano roll from your DAW.
Playing with the MIDI NeoPixel Visualizer
With the Feather RP2040 PropMaker setup as an external MIDI device in your DAW, you can use a MIDI controller such as a keyboard piano or control pads to light up the LEDs.
When a single MIDI note is played, a corresponding NeoPixel LED will light up. When multiple MIDI notes are played, as a chord, multiple LEDs will light up.
