Current Behavior

I'm experiencing issues with the transposition feature not working as expected. When I set transpositionPitches: [-4], the notes incorrectly go below 0. Instead, they should move up a string rather than displaying a -1.

Steps to Reproduce:

  1. Open the attached guitar tab file with no transposition applied (see Screenshot 1).
  2. Set transpositionPitches to [-4].
  3. Observe the transposed guitar tab (see Screenshot 2).

Expected Behavior:
The notes should transpose correctly by moving up a string instead of displaying a negative value, as demonstrated in the expected output from Songsterr (see Screenshot 3).

Screenshots:

  1. No transposition applied:

  2. After Setting transpositionPitches to [-4]:

Expected Behavior

The notes should transpose correctly by moving up a string instead of displaying a negative value, as demonstrated in the expected output from Songsterr (see Screenshot 3 above).

Steps To Reproduce

  2. Set the Transposition:

    • Open the downloaded file and set transpositionPitches to [-4].
