Hello all, sorry i don't reproduce it .
i did an intense recheck last night :
- GO back to previous prod fw 2.1.4.930, modified settings on hardware (took screenshot from MCC), updated to 3.0.6 -> no setting has changed
- Go back to previous prod fw 2.1.4.930, modified settings from MCC (took screenshot also), updated to 3.0.6 -> nothing have changed
i also ensured that the factory settings are strictly the same between both firmware versions.
So i have no clue here, but i would suggest you to check midi settings , especially Midi merge, as suggest by one other user on this board, in another topic. As a reminder :
USB + Keyboard : only midi notes played on MF keyboard or from DAW in USB (i.e midi clip) will produce sound
MIDI + Keyboard : only midi notes played on MF or external device (using MIDI DIN) will produce sound
BOTH + Keyboard : nevermind the source, it will produce sound.
if the setting look right on the HW and also in MCC, but the MF is still not able to produce sounds from Incoming MIDI DIN notes, i suggest just to change setting and go back to either MIDI + KBD or BOTH + KBD
hope this helps,
best regards
