However, it will only create one MIDI track per staff line. The greatest variable in recognition accuracy is the quality of the printed music to be scanned. Larger fonts with crisper, more detailed printing will have better accuracy than smaller, faded scores or copies out of multiple generations. Avoid scores having broken, faded or segmented note stems and staff lines. Good scanners work best The next greatest variable is the quality of the scanner used.
