Any input key can be mapped to any output frequency. Because alternate tunings can have more than 12 notes per octave, more than one input note may be be mapped to the same output note. Therefore the pitch bend is associated with the input note, not the output note. Specifying an output note is optional. If none is specified, the output note is understood to be the same as the input note. | Any input key can be mapped to any output frequency.
