Muse Sustain Pedal

So I just got a Muse, Loaded it with 1.3 and seem to have a problem

I have both a Sustain Pedal and an Expression pedal plugged in, Expression assignable controller works just fine with the expression pedal, but as soon as I step on the Sustain Pedal, the Expression Light goes off and no more working expression pedal. Why ?

Is there a way to make these separate or is this always the case? Doesn’t seem like it should work this way. as they are two separate functions.

I’m going to test this later.
I have an issue with aftertouch, but the midi monitor shows that there is response on MIDI CC 64 when I press Aftertouch.
Since this is related to peda input, I wonder if we have similar issues.

I will come back to it later.
