[linux-audio-user] MIDI getting killed by Jack?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
   Is anyone else experiencing this problem? I set up a bunch of
aconnect commands to route my keyboard controller (64:0) to a number of
synths on different MIDI interfaces, and also to route the output of Pro
Tools (on another computer) to pretty much the same places:

aconnect 64:0 64:32
aconnect 64:0 80:1
aconnect 80:0 64:0
aconnect 80:0 64:32
aconnect 80:0 80:1

I also route Pro Tools output back to my keyboard (line 3) in case I
want to plug another hardware synth in there, but nothing is hooked up
to that right now.

At this point I set up my mixer and play. Everything works and is
perfectly fine for long periods of time.

I then start Jack and within a minute or two I lose MIDI connectivity. I
can run alsaplayer or other audio apps and I still get audio, but there
is no more MIDI connectivity. I look at the synths and they are not
receiving MIDI input. (No event lights.)

I then stop Jack and I immediately hear a bunch of MIDI notes get
played.These notes were stored from when I wasn't getting connectivity.
At this point I have MIDI back for live playing until the next time I
start Jack when it happens again.

I do this 4 or 5 times and at this point I cannot get MIDI back at all.
I have to completely power down as far as I can tell. I tried rebooting
and had no luck the one time I did that.

I don't know what to look at to figure out what could be causing this.
Hardware and modules shown below.

Thanks,
Mark
