How about anybody with any stories to share about getting the Motu MTP AV USB (with brand new up to date ROM installed) working in Linux? The alsa driver is MTPAV.ko, I have it apparently by default in ubuntu studio 10.04 and AV Linux 5.02 but it is completely ignored or there is some step I need to do before getting the MOTU recognized in linux. I'm watching an auction on ebay for an Edirol UM-880, but the price is set at $440, about twice what I paid for a used Motu MTP AV USB several years back.ĭoes anybody have any stories to share about using a Edirol UM-880 in linux?

Try starting the jack daemon first, from a terminal or using Alt-F2. Is there a way to make these accessible to a normal user account (and allow Jack to pass the midi events to the appropriate applications) ? I looks like some security is preventing QJackCtrl / Jack to attach to the midi devices. (which should allow real-time prioriry for the Jack deamon).

Next, I logged on as root, and everything worked fine !! However, with this device the same problem: I cannot make a connection in QjackCtrl. After the firmware has been loaded, the led’s show that the device is active and is transmitting midi events. I also connected a different midi input-output controller a M-Audio MidiSport 2x2, which is known to work in linux. And of course no sound is made when playing on the keys. I installed a virtual midi keyboard, which I can connect in QJackCtrl to the soft synth and it will sound the notes /keys I press.īut when trying this with any of the three midi output devices of the KX which are listed in the QJackCtrl input devices list, qJackctrl will silenly refuse to make / draw a connection. All ports of the KX device are present in the devices list of QJackCtrl (and show up in the output of lsusb). I have connected a new Yamaha KX-61 USB midi-controller keyboard, but in QJackCtrl I cannot make any connection from the keyboard to any midi-input (a soft synth like Qsynth). I’m running openSuse 11.1 (64) and have problems getting midi input devices to work. ![]()
