A Wished-For Feature

Greetings,

Here's something that's driving me nuts. Two of my favorite MIDI instruments are old enough not to respond to "All Notes Off" and "All Sounds Off." These are the Casio CZ-1000 and CZ-101; I use them in most of my recordings.

As a consequence, when aborting a recording, or playback during rehearsal, it is most often the case I suffer from stuck notes on these two otherwise superior instruments. This requires me to get up from the computer, and go to the instruments themselves to unstick the notes. Given how many run-throughs my decrepit hands need to get a recording right, this get old very quickly.

I would love to see something like my old Cakewalk on DOS had: it could send a string of Note-Offs in lieu of the All Notes Off command, when hitting the space bar to abort a recording/playback. This greatly improves the workflow.

Would it be possible to incorporate this as an optional setting, or at least make it available in the panic button?

Thanks for listening.

hi,

it is available at least for playback only since v0.9.34, pending note-offs are sent on stop and/or on panic button.

sorry

Hi again,

Well, call me a dunce, but I'm not seeing the option to automatically send multiple Note Off events. I'm using Qtractor 1.4 on a Linux Mint 22 Xfce machine.

Here's what "aseqdump" shows when I stop the playback:

Note 67 remains stuck on my Casio CZ-1000, which is on channel 1 (0), and I have to turn it off at the Casio. Neither the Stop function of Qtractor or its Panic Button has any effect. The multiple Not Off events don't appear in the dump.

Where am I going wrong?

Thanks,

Thomas

so,... where are those note-on events coming from?

as said, it is only supposed to work over playback of already stored MIDI clips, for notes that are still lingering on when stop or panic button is hit.

it doesn't apply to notes that are incoming for recording or just passing-trough (monitored).

if that note 67 is not sourced on any playback material (eg. MIDI clip) then it won't get a note-off when you hit stop or panic whatsoever.

cheers

Hi,

This log is from the playback of a recorded and already stored MIDI track on channel 1 (0). I started up aseqdump, connected it to Qtractor, then set Qtractor playing. Nothing else was being processed or inputted. So, Note 67 was recorded previously and played back.

For emphasis, this was playback only from a recorded track.

Thanks for your attention.

Thomas

if that's true then it's a bug or lost feature somewhere...

I'll try to investigate...
