Hi guys I have been playing around with the git version from yesterday. I have experienced some unusual behaviour with jack transport. Occasionally playback will cease after stopping and starting. I'll outline my setup: - I have both jackctlmmc and a2jmidi daemons queued to start after jackd starts. - Qmidiarp in jack transport mode - I have a midi controller sending transport messages to jackctlmmc Jack midi port - midi controller also sends input to a Qmidiarp sequencer - seq24 sequencer with jack as transport master (midi out to hydrogen) - Qmidiarp output port to either/and yoshimi / hardware synth Two issues I have noticed 1 - if I rapidly stop start jack transport via the controller occasionally qmidiarp will only play the first note and playback will stop 2 - if I have set the midi sequencer to retrigger on input occasionally playback will stop - however subsequent note velocity input can be seen to update the GUI In the first instance stopping and starting transport will cause the playback to continue In the second its not immediately apparent how I can restart playback - usually a combination of turning off jack transport / stopping / starting / stopping Qmidiarp and re-enabling jack transport. In all cases seq24 receives and acts on transport messages correctly. Anyway - I hope this is clear. Let me know if there is anything else you need. regards, Brendan |

Could you try with the current git ? (2) is something I don't get here so it probably didn't change for this issue. Thanks for the feedback Cheers Frank |
