How can I notate the correct accidental(s) for a MIDI import?
Some MIDI files do not include the relevant information about the key of the piece of music. capella however can find and set the correct accidentals as follows: Mark the entire score with menu edit | mark | entire score ([Ctrl] + [A]). Transpose the score into the assumed correct key with key change via menu format | transposition ([Alt] + [F5]). While the entire score is still marked, execute a reverse transposition by the same interval without key change.
