[AmKiwi]

Is there an existing issue for this?

Current Behavior

Bass tracks on .gp3, .gp4 or .gp5 files display with a treble clef in sheet music view, with notes far below the staff (as they are low notes).

Expected Behavior

I expect bass instruments tracks to be displayed with bass clef in sheet music view.

Steps To Reproduce

1. Upload gp3 file with bass tracks in alphaTab playground (https://next.alphatab.net/docs/playground)
2. Switch to bass track and ensure sheet music view is enabled
3. See the treble clef

Anything else?

This does not occur with .gp files (guitar pro 7 i think), where bass instruments show with a bass clef in sheet music view. Percussion instruments still display with neutral clef. The gp3 bass tracks render with bass clef in tuxguitar.

This is rather a feature than a bug due to the fact that the Guitar Pro 3-5 files do not explicitly hold any information about what clef to show. It is up to the application to dynamically decide which clef to show.

After some basic fiddling I noticed that Guitar Pro 5 has this behavior: If the tuning of the lowest string is below a B2 they switch to a F4/Bass clef. Should be fairly easy to add this behavior to the importer.
