At least the power issue is solved by a powered USB hub [1].

At the moment I have no time to test it, however, Music Studio 2 shows Core MIDI (AudioBox 1818 VSL) For recoding audio Music Studio 2 offers to select between Mono L Mono R 18 mono files 9 stereo files Inter-App Audio but I didn't test recording audio or MIDI yet. Audiobus doesn't stop "Refreshing...", if I want to select an input or output. Perhaps I didn't wait long enough. Even without launching Audiobus I can't hear an audio signal on any of the 18 channels (8 analog, 8 ADAT, 2 S/PDIF), when playing an instrument with Music Studio 2 or Animoog." _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
