I asked this question in a comment in a bug report, and nobody caught it. Here's a typical example:
Key == C major Transpose == -2 Notation wants to be written at D major to sound correctly. It goes up by two accidentals. From zero accidentals to two accidentals. Now how do you handle that when the number of accidentals gets higher than 7? I don't have the foggiest clue, and don't even know what to google for. I doubt an answer is out there in terms of -2 and +2. It's probably about minor diminished 13ths or something, if it's out there at all. So what's the formula here in code terms? Something like concert_pitch_key_accidental_count - segment_transpose_property would work for most cases. Key == C major, concert_pitch_key_accidental_count == 0. Transpose == -2 0 - -2 = 2 The key with +2 accidentals from C major is D major. Or the opposite Key == C major, concert_pitch_key_accidental_count == 0 Transpose == 2 0 - 2 = -2 The key with -2 accidentals from C major is Bb major. That much seems sane, reasonable, and predictable, but what happens when the number exceeds +/- 7? We don't support keys with more than 7 accidentals, and I wouldn't expect it to be common for a -33 instrument to read a key in Key == C major, accidental_count = 0 Transpose == -33 0 - -33 = 33 33 accidentals. What the hell kind of crazy key would that be? It would have to have triple sharps or something. So I'm sure there is a perfectly sane solution to this, but I haven't a clue whatsoever what that solution might be. Help? Please? Anyone? -- D.
