After updating to the latest firmware, several times while playing live jams, I had a situation in which while extending the pattern in the sequencer, suddenly, for no reason, it muted all the sequencers. From what I’ve noticed, it happened while copying a fragment of pattern 1-16 to the other tracks (paste on tracks 17-32 and on). At some point, randomly (it doesn’t always happen) all sequencers were completely muted, but the MUTE highlighting didn’t change. Pressing MUTE several times for all sequencers at some point restores the sequencers.
