OK that seems to work fine, and the USB midi interface shows up when i run amidi -l :-) i created a virtual midi device that dumps incoming data in a terminal window (using amidi -p virtual d), and connected the midi input port of the USB interface to that virtual interface (in qjackctl) then i connected my FX unit to the usb interface and configured the FX unit so it sends midi messages whenever i turn the 'preset select' knob on the FX unit the midi data shows up in the terminal window if i then send this midi data back tot the FX unit (using amidi -p hw:2,0,0 -S 'C1 09') the unit jumps to the correct preset :-) however, this does not work when jack is running. if jack is running i get this message : ALSA lib rawmidi_hw.c:233:(snd_rawmidi_hw_open) open /dev/snd/midiC2D0 failed: Device or resource busy cannot open port "hw:2,0,0": Device or resource busy looks like jack claims the device. this is blocking for me since i need to have jack running for my audio routing :-( any ideas ? grtz Thijs > > > Regards, > Clemens > _______________________________________________ > Linux-audio-dev mailing list > [email protected] > http://lists.linuxaudio.org/listinfo/linux-audio-dev > -- follow me on my Audio & Linux blog <http://audio-and-linux.blogspot.com/> !
