Hello, thanks for replying.
Yes, SAVE MUTE STATES is on. I can reproduce this behaviour easily and consistently.
I set track 1 to 4/4 time, length 1 measure, and track 2 to 5/4 time (polymeter mode), length also 1 measure.
I assign (by default) pattern 1 of track one to sequence 1, pattern 2 of track 2 to sequence 2.
In Track mode, now, in sequence 2, both tracks are active. If I mute track 1, the mute state is not saved regardless of whether the Rec button is on.
Also, when ordering my sequences in the play list in Seq mode, I cannot set sequence 2 to play the full 5/4 measure. If I set duration to one measure, it will only play 4 beats instead of five. If I set it to two if will play the 8 beats, etc.
I undetstand this is, most likely, rather technically challenging, but a solution to this would make Pyramid so much more versatile.
