I am experiencing open/held notes during extended playback and even when the sequencer is stopped with my Beatstep Pro. MY setup is as follows currently:
Roland MX-1 as my master and clock source, synced via midi in to the BS Pro. I have the BS Pro midi out connected to a Roland Aira System-1m, then the midi out from the 1m to my Microbrute. Sequence one is triggering the 1m, while sequence 2 is triggering the Microbrute.
Playback starts fine but after a few minutes of playback, both the 1m and Microbrute, while still playing the programmed sequences, starting holding a open note. Stopping the MX-1 correctly stops the BS Pro from playing the sequences, but the single note from the 1M and Microbrute continue to sound. I have to power off both synths to get it to clear.
I have updated the firmware in both units and this still happens. Just using the BS Pro as the master directly to the synths is causing the same issue, and as the MX-1 is not a sequencer, I assume the issue is something between the BS pro and the synths.
I have not tried using the CV gates yet to see if the issue is duplicated and am only connecting everything via midi at the moment.
Any suggestions would be appreciated as to what I may be overlooking, or if anyone has experienced this problem and has a fix, please let me know.
