Hi,
has anyone succeeded in using a Pico as MIDI USB host?
I want to build a converter from USB MIDI to serial MIDI: the keyboard with USB MIDI shall be connected to the converter, which allows to connect it to normal serial MIDI.

I have searched a bit, but I didn't find something really useful yet.

I'm not quite sure that USB host mode is quite there yet on RP2040 to do that. I'd love to be wrong, though.

I have managed to connect a Akai LPK25 keyboard (USB MIDI out) to a Korg NTS-1 (3.5 mm MIDI in) using an Adafruit Trinket M0 (ATSAMD21) and this Arduino code: gdsports/midiuartusbh: MIDI DIN to MIDI USB Host Converter. It works better than I expected.

Thank you!
For the moment I have resigned and instead of doing it with the Pico I have ordered a USB host board:

It seems that this converts from USB MIDI to serial.

I have just tested this board and it works fine!
