Broken MIDI Adapters - GrandOrgue/grandorgue GitHub Wiki

There are some kind of broken MIDI adapters out there. They are usually cheap USB-MIDI interfaces, which are not able to transmit all MIDI messages correctly.

Here is a collection of user report:

• Midi-USB-Interface DigitalLife https://mps-orgelseite.de/home/forum/index.php?thread/1289-grandorgue-grunds%C3%A4tzliches-funktioniert-nicht/

Please append other error reports of other MIDI interfances (and also reports of fixed versions).
