Win 11 and cantabile MIDI disconnects and requires reboot

Cantabile
1

I was on a break for about 8 months (singer diagnosed with cancer).

It used to be that as long as my laptop remained on, Cantabile would stay connected and i could come back to where II left off (sometimes there was hiccuping when i played the first few notes but then it paged things back in and everything was fine).

More recently if i leave the laptop on after a while (I’m trying to nail this down, but more than :30 minutes), MIDI from the MODX keyboard no longer works, but audio is just fine (i can play the cantabile sounds from the onscreen keyboard).

If i try to shut down cantabile it hangs and much of the time even Task Mangler won’t kill the Cantabile process. The only way I’ve been able to get it working again is to restart the laptop.

Powernprofile is high, so it shouldn’t be putting that port to sleep, but it’s the same physical port as the audio so that doesn’t make sense. .

I don’t know if this is a Yamaha driver issues, a win 11 issue, or cantabile.

I thought it was just a fluke last week at rehearsal, but it happened again at the gig (sound check to downbeat was long enough to cause it.

Any ideas where to start to debug?

I would try to separate the debug process. Try using MIDI-OX to debug if MIDI receiving stops after some idle time, without involving Cantabile in the picture. Or you could use MIDI-OX to check if MIDI arrives from the port even when Cantabile is not reacting to it.

I also wonder if your laptop received the windows update that people is talking about here:

New Windows MIDI services - heads up; a breaking bug!

possibly creating some issues.

You could also try to uninstall/reinstalla Yamaha ASIO driver.

The fact that Cantabile hangs and that it is not possible to close it could also point to an hardware issue.

Just my 2 cents,
Gabriel

Hi. Are you using USB MIDI?

If so then check that USB power suspend is not enabled. Windows has a habit of overriding those settings after an update.

Thank you both for the suggestions.

  • I am using USB MIDI and am double checking the power settings for it, but it’s the same physical cable for MIDI and Audio (both come from the MODX). It’s almost as if the driver is going to sleep.
  • It’s funny that Cantabile doesn’t crash UNTIL I try to close it. I can play sounds from the on-screen keyboard with no issues.
  • I saw the update post about MIDI a while ago. I’ll look deeper into thi as well.
  • I have two nearly identical machines (software is the same, not the hardware), and it’s only happening on the one machine (which is the newer, more powerful on, of course) .

I’ll try the diagnostics ideas, starting with Cantabile (to see if is processing any of the MIDI input).

The unfortunately thing is that I have to leave the laptop for a significant period of time (and I’ve got a rehearsal tonight so I want to keep playing it.

I’ll update this thread as I go through this process.
