This unit works great using UiFlow and the Grove UART connection. I have been unable to get the synth to respond to MIDI input from an Arturia MINILAB 3 via either the MIDI IN or TRS IN connector. The MIDI signals coming from the MINILAB and going in to either of these two connectors are correct and verified with a logic analyzer.
I am new to MIDI - am I making a beginners mistake or is it not possible to send a MIDI note in to this device from a keyboard?
