A simple bug, but a very annoying one:
Steps to reproduce:
Set LFO to free running.
Have an external device (in my case an mpc1000 running JJOS2xl) send midi clock sync to the minibrute, so the arpeggiator syncs.
Stop the midi clock signal.
Minibrute returns to internal clock (which is another behavior I think should be changed, the automatic clock selection), but the LFO now runs synced to the arpeggiator, even though the switch is set to Free. Turning the LFO knob or flicking the LFO sync switch to Arpeggiator and back, returns the LFO to free running mode.
Quite irritating. For example, I had a slow PWM going with the LFO, and whenever I stopped the sequence on my MPC, it would switch to an annoying fast warbly PWM sound.
