Troubles with UM-ONE USB-MIDI #15

Closed Sgw32 closed 1 year ago

Sgw32 commented 1 year ago

MC6850 processes a constant output of 0xFE with this device. Some more info here: https://www.vguitarforums.com/smf/index.php?topic=22712.0 It is called "Active Sense"

I can't flash anything to the device, because flashing corrupts while writing(and maybe it is related, maybe not) Seems like Kerberos is for cheaper USB-MIDI devices ;)

Now I can confirm that even if it puts 0xFE to the list of commands, flashing still works. It was a hardware fault. Closing this issue. Solved: 0xFE does not interrupt flashing. Roland UM-ONE confirmed working.
