Hey Harley, well as you say that's not what's supposed to happen (I assume here that tremolo (B3), loop (B4) and tuner mute all work normally ?).
I need to have a read of MP2 CC now I understand it better and also work out the macros.
My initial thoughts are that it's maybe a latching missmatch issue (not the latch/momentary option in the quad switch (set with the dip switches)) but in the MP2. This is talked about in the MB1 level 2 release notes (MP2 I need to read..), there's a global option for how the unit responds to latching (so if the chorus is staying latched when it shouldn't
). The other thought is maybe it's a macro being triggered ? which turn chorus on ? Again need to read how macros work and what instigates/operates them, eg maybe the CC# of the chorus button is assigned to one ?? CC#s can be assigned to multiple things at the same time.
Anyway I'm guessing, but it definitely shouldn't be behaving like that.
