Configure MIDI device per session

[wargreen]

Describe the bug
When loading the LiSP session, we need to manually recall the MIDI input device

To Reproduce
Steps to reproduce the behavior:

1. Save a file with another MIDI input device configured
2. Close LiSP
3. Load the session
4. See the "AppDefault" in the input device

Expected behavior
The input device is part of the session, we need to recall it when we load a session.

Linux Show Player version:

• 0.5.3

OS Version

• Debian SID

[s0600204]

The preferences dialog found on the File menu sets configuration globally and for all sessions.

It is not possible with version 0.5.3 to set settings on a session-by-session basis.

It should be possible with version 0.6 combined with PR #144, but a suitable config page to set the MIDI devices for the active session would still need to be implemented. (This exact issue would be a good use case for getting that PR merged, btw.)

If LiSP (0.5.3) is not restoring the set MIDI device on application restart, then that is a separate issue (and one I cannot duplicate).

Ok i understand. 0.6 will be a very good update !
I need to check, but it seem that 0.5.3 don't restore the midi device. I'll open another issue when i've clearly checked that.
