Package: qtractor
Version: 0.4.8-2
Severity: normal
(This arguably causes data loss.)
To reproduce:
1. Start up Qtractor. Connect a MIDI source to its Master bus using
the ALSA sequencer.
2. Create a new MIDI track named "Foo / Bar", assigned to channel 1.
3. Arm the track for recording, then enable the master record arm
with the red record button. Create a new session of any unused
name when/if so prompted.
4. Start the transport using the play button. Play MIDI notes on channel
1. They will appear in the timeline as they are purportedly recorded.
5. Stop the transport using the play button again. The MIDI clip that
has just been recorded now contains no visible events.
6. Double-click on the clip to open it in the clip editor to confirm
that there are no events. (It additionally has no apparent name
and shows up with the name of the session's containing directory,
which are less serious anomalies.)
Observe that a track named "Foo ; Bar" (with a semicolon instead of a
slash) does not experience the same behavior.
My wild guess is that since the track name is used as part of the name
of the backing store MIDI file, the slash isn't getting denatured from
its role as a directory separator, so creating the backing file fails
due to a bogus nonexistent path component, destroying the recorded
data. (At least, I haven't found any obvious way of getting it back.
Fortunately I was able to record it again after figuring out what was
going on.)
