Hi all,
Recently set up 2x AL-88c via a switch and am getting frequent dropouts - MIDI notes stop/hang, AL-88c's disappear and/or flicker from CopperLan Manager application window.
Also, all connections I had made from AL-88c MIDI "ins" to computer's VM ports have disappeared and a few anomalous connections which I didn't make have mysteriously appeared in CopperLan Manager (for instance, output AL-88c port 1 routed itself to AL-88c input port 8 in between sessions for no apparent reason).
Set up:
Copperlan Hardware:
1x MacBook pro unibody 2012, 2.7GHz Quad-core Intel Core i7, OSX 10.8 Mountain Lion
1x Cisco SF100D-05 5 Port 10/100 Desktop Switch plugged directly into ethernet port on MacBook
2x AL-88c plugged into switch, nothing else on switch. (Internet etc. are all on wifi)
USB/FW MIDI devices (connected but not currently configured in Copperlan - definitely planning to once AL-88c's are working properly):
1x MOTU Express 128
1x Elektron TM-1
1x Evolution UC-33
1x M-Audio Trigger Finger
1x RME FF800
Software Installed:
Ableton 9
Logic Pro X
Pro Tools 10
Reason 8
Numerology 4
MidiQuest 11
So far, I've only tested this with Ableton sending MIDI but from troubleshooting and watching the dropouts happen in Copperlan Manager, I think the Cisco switch is causing the dropouts as neither AL-88c seem to have any problems when they're plugged in alone. The switch is brand new, I guess it could be defective but would like to know if there's some network config I can try to make this connection stable?
Also, is there a reason Copperlan Manager "forgot" half my routing between sessions and created its own connections? - I have 30+ MIDI devices so I don't want to be redoing my config every time!
Really great protocol/program btw, will be indispensable once I've got it all working properly!
Thanks,
Tobias
