Detailed Description

Difference between detected and expected pitch.

Place this in a series after Yin (or any other pitch-detection MarSystem), and feed it the expected pitch as a control. Outputs the difference as a midi pitch value.

Controls:

• mrs_real/expectedPitch [w] : expected pitch
• mrs_bool/ignoreOctaves [w] : useful if the pitch detection algorithm has octave errors, but is otherwise relatively accurate (default false)
• mrs_bool/absoluteValue [w] : outputs the absolute difference (default false)
