TABs do not (properly?) support transposition
Context: today github master, but the issue is present since quite some time.
Full discussion is in this forum thread , which however intermixes another discussion about dialogue boxes; so I open this issue to clean up the situation.
However, data given there seem to be in conflict with GuitarPro import strategies; in particular, the way the test files
fret-diagram.gp5 are imported into reference files
fret-diagram.gp5-ref.mscx respectively (in
mtest/guitarpro folder of sources).
These imports do not seem themselves correct, though. For instance
fret-diagram.gp4-ref.mscx, which squeezes a 7-string guitar with augmented fourth up transposition (to emulate a capo 6) in a 6-line tab, results in:
(source GuitarPro file and resulting imported reference file are attached).
Putting aside the 7-string vs. 6-line question (which results on marks for the 7th string to appear in the 1st, but is a different issue), the specific fretting used here is been probably set in Guitar Pro and seems to imply a different convention.
More data are needed to devise a solution for the issue.
