ESP32 MIDI client and chord recognizer
This sketch uses the MusiQwik font to show the MIDI notes. The font file font.vlw should be in the SPIFFS partition.
To upload the font use following PlatformIO command:
pio run --target uploadfs --environment core2
In VS Code use: PlatformIO -> Project Tasks -> Upload Filesystem Image
Alternatively define UPLOAD_FONT when building the image (uncomment following line in platformio.ini)
; -DUPLOAD_FONT
