I'm using Ardour as a newbe and get stuck while adding a MIDI track with a-Fluid Synth as a instrument. I'm able to bind my MIDI Controller (Launchkey 25) to input. MIDI signals are shown when I hit a key but no sound comes out. If I add a MIDI track with a-reasonable synth as instrument, there is sound.
While searching for a reason for that behavior I saw the message "[ERROR]: JACK: Cannot callback the server in notification thread!" in the Ardour Log window.
- I am wondering, what this message means.
- How to get sound with other instrument than a-reasonable synth
