Hello, I need help! I’m having problems displaying the keyboard that appears at the beginning of the track.
I add the MIDI track normally, but when I expand it to display the keyboard, the program closes unexpectedly, and so it always is, I don’t know if this would be an option or a bug, my pc is Ubuntu 20.04.2 LTS x86_64
Thank you all!
Which version of Ardour is that (Ardour > Menu > Help > About)?
Is that Ardour from Ubuntu, or from
Also which synth-plugin are you using on the MIDI track?
The version is: Ardour 5.12.0
I installed the program directly from the ubuntu store, and the plugin, only has these two being used (I’m still new to the program)
Looks like “Reasonable Synth”.
In any case this issue is unusual, I don’t have any immediate idea why this would or how this could cause Ardour to crash.
Perhaps try a recent version of Ardour 6.6. from
https://nightly.ardour.org/ (demo is fine, can be installed in parallel to Ubuntu’s version) to rule out that this isn’t something specific to the Ubuntu version and/or your system.
I installed version 6.6, but the problem continues, I can’t expand the midi track to the point where the keyboard appears, it crashes before
the terminal showed this error message before installation:
System failed the quick sanity check… Looking for the cause
!!! WARNING !!! - Your system seems to use frequency scaling.
This can have a serious impact on audio latency.
For best results turn it off, e.g. by choosing the ‘performance’ governor.
Press ENTER to continue:
!!! Install Complete !!!
I don’t know if it can have anything to do …
With Ardour 6. You can also use Menu > WIndow > Virtual Keyboard to play.
This is a mystery. Never heard of an issue like this before, especially not one that happens in both Ardour 5 and 6.
A backtrace (see
Debugging Ardour) might shed some light.
In short start Ardour inside a debugger:
then inside gdb:
run <press enter> and when it crashes:
bt <enter> copy & paste the result here on
I started ardor in debug mode, when it crashed when expanding a MIDI track, the terminal went crazy showing this snippet:
this was the departure of “bt”
Thread 1 “ArdourGUI” received signal SIGTRAP, Trace/breakpoint trap.
0x00007ffff2f15278 in g_logv () from /opt/Ardour-6.6.542-dbg/lib/libglib-2.0.so.0
where do I paste on
Edit: it looks like someone has already reported this bug, but I can’t find any answers.
instead of leaving, could you run
