![]() On Vista there is an awful delay of 0.2 seconds, caused by the default Microsoft soft synth for the on-board audio chip. Even without optimizing the jack settings from my fast system, there is no noticeable delay between hitting a key and hearing it. or switching of AppArmour needed a reboot to have effect.Īfter a week searching and trying, I’m very pleased now with the situation.or start qjackctl as root using sudo (couldn’t get it running as it complained about a missing X screen). ![]() trying running jack from the commandline (qjackctl cannot attach to the jack server, not very handy, but a different tool -patchage- can do the patches but it didn’t help),.jackd -n 3 -d alsaĪfter a reboot it functions normally now! 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). In /etc/security/nf the following lines are - rtprio - nice - memlock 4000000 I switched off AppArmour, but that did not help.īoth midi devices work normally in Windows (vista-64 / XP). Next, I logged on as root, and everything worked fine !! The defect affects only the MIDI input and causes the MIDISPORT Uno to distort incoming MIDI data resulting in random notes, inaccurate note on/off messages, as well as pitch bend. However, with this device the same problem: I cannot make a connection in QjackCtrl. M-Audio has identified a defect in a manufacturing run of its popular MIDISPORT UNO 1x1 MIDI interfaces. 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. ![]()
