Originally I wanted to ask if this behaviour is on the Arranger Mode normal: Arranger Tips - #114 by Jeanne
Now that it is established that it is unfortunately normal, there’s still the bug that mute and unmute in Arranger mode is unreliable:
Video where I had to hold my iPad with one hand. Super primivite project with one-shots, not loops.
as one can see, muting and unmuting while the row plays does nothing, until i hit stop-play. That is contrary to Song Mode on the Digis (and A4). But that does seem to be unfortunately normal for Octatrack.
But I could catch the unreliability only in the beginning of the video: One can see that it is already stopped, I unmute two tracks, hit play (all very slowly) and the unmuted track don’t play even though there’s a lot of time between the button presses. And this happens a lot of times.
