I suggest using a MIDI monitor to check each step of the process to make sure that each component involved in outputting MIDI messages is outputting the correct bytes. Possible monitoring points include: * MIDI produced by the application that communicates with the FCB1010 (if this isn't possible inside the virtual machine, then try running the application in `wine`) * MIDI output by the virtual machine (I'm not sure if you can create a virtual sound card for a VM or not) * MIDI output by the MIDI interface (use a MIDI split device, or, possibly, the MIDI thru port of the FCB1010) I'd be interested in knowing if the problem goes away if you run the program via `wine`. -- Devin Anderson surfacepatterns (at) gmail (dot) com blog - http://surfacepatterns.blogspot.com/ midisnoop - http://midisnoop.googlecode.com/ psinsights - http://psinsights.googlecode.com/ synthclone - http://synthclone.googlecode.com/ _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
