MIDI to CV with Arduino (Hagiwo)

@HAGIWO writes there:

Also, since serial communication with the PC is not possible, the serial monitor of the Arduino IDE cannot be used either.
(Maybe there is a workaround)

One workaround is to use the SoftwareSerial library for MIDI, freeing up the hardware serial for the serial monitor. Unfortunately SoftwareSerial is too slow for MIDI when using a sequencer or the like, but it could be used to debug with single key presses. Then switch to hardware serial when done debugging.

Another workaround is to use an OLED display for diagnostic messages.

Garbage in my MIDI

I’ve breadboarded a MIDI in circuit with a Nano and am running a sketch that listens for MIDI messages and prints them out. It uses SoftwareSerial for MIDI so it can write diagnostics to the serial monitor with hardware serial. Or it can be set up to use hardware serial for MIDI and write no diagnostics; it flashes an LED when it sees a MIDI message of the type or types I specify. And I’m getting garbage. I’m using this for MIDI In: [image] The worse problem is with the Arturia Keystep. If …
