No MIDI sound..

Hi all..
Finally got everything up and running (qjackctl, qtractor) and although I can see input from my USB midi keyboard (midi-man 49 keystation) but I get no sound..
I have created a midi track, chosen a synth, picked a soundbank (e-piano) and then called up the mixer and clicked monitor for the master and the individual track.. Can see the input fader going up and down as I press the keys but no sound is coming out.. Have been at this for hours now trying to get some noise out but no joy..

I have audio working perfectly, this just seems to be a MIDI thing.. The midi seems to work ok in Ardour, but I want to use Qtractor and I cant seem to get past this problem..

Any ideas anyone..?

welcome to the party :)

please do check on the following while you have your session on screen:

  1. over the MIDI Track > Track Properties...
    • what MIDI input/output buses are--should be Master In/Master Out by default;
    • which MIDI channel is the track assigned to--this has to match the incoming MIDI events from your keyboard; however there's a convenience workaround: on main menu, set Track > Auto Monitor on;
    • make sure the synth instrument plugin's is activated--the green LED on its left is lit (ie. is obviously green, not black); if not, click on it to turn it on;
  2. on the Mixer window, Master in (MIDI) input bus strip, hit "inputs" and then "Connect" this to your MIDI keyboard controller, whatever it is, if not already;
  3. on the Mixer window, Master out (Audio) output bus strip, hit "outputs" and then "Connect" those to system/playback_1,2... ports, if not already;
  4. make your MIDI Track current, by just clicking on it or navigating over it; again, make sure Track > Auto Monitor is on (remember 1.);
  5. hit the keys on the keyboard: MIDI Master In level meters should go up and down as you press those keys, I guess you already acknowledged that; but then, the MIDI Track's meters should also follow suit; then look at Master Out (Audio) meters, they should show some peak signals and if it's all connected right you should hear sound coming out from your speakers (or whatever is physically connected to your soundcard device line outputs, hea(d|r)phones, etc.

I believe you overlooked one single of those steps--most probably to activate the plugin--the little green led case--you tell me :).


I cant thank you enough.. You were spot on, it was not activating the plugin, that little green light.... Feeling a bit daft to have missed that (I didnt miss it when doing audio) but that is over-ridden by the joy of it all working now..
SOUND AT LAST...!!! If I knew who you were I would put at the top of my xmas card list..

Gonna have a real good play now its all working..
Thank you soooo much again.. :-)
