I am using FM3 with FC6.
After updating to fw 3.02 two weeks ago, I have experienced the following problem 6 times.
LEFT SWITCH:
Tap assigned to Tap Tempo. Ring color assigned to None. Pressing switch doesn't change tempo. Several times also the ring colour displays in red
Hold assigned to view change. Holding the switch doesn't change view
MIDDLE SWITCH:
Tap assigned to Scene -1. It doesn't change scenes. Color is correct, purple. I can change scene via buttons of the unit and also with FM3 Edit
RIGHT SWITCH:
Tap assigned to Scene +1. It doesn't change scenes. Color is correct, purple. I can change scene via buttons of the unit and also with FM3 Edit
The FC6 unit is not affected, it works always fine. When I go to the Master Layout via the FC6, and I press a footswitch on FC6 that changes the layout of FM3 and FC6, the FM3 doesn't respond, but the FC6 changes to the new layout.
Inside the FM3 everything works fine if I use the knobs of the unit, or FM3 Edit. But the frozen footswitches never respond, the only solution is to restart the unit.
I tried the new tuner features after installing fx30.2, but as I didn't like it, I disabled it after 2 minutes. So, in my case, it seems there is no relation between the tuner and the freeze of footswitches.
I open the tuner with pedal heel down.
