Assumptions & limits

Assumptions & limits

  • Integer semitone pitch translation in 12-tone equal-tempered MIDI naming only. Octave numbering, acoustic tuning, enharmonic spelling and instrument range are not inferred. Supported limits: 1..128 MIDI integers 0..127; interval -127..127; all concert notes must remain 0..127.
