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 64:X - HDSP 9652 80:X - MidiSport 2x2 Wizard root # lspci 00:00.0 Host bridge: VIA Technologies, Inc.
