MidiPitch Class Reference

#include <lomse_pitch.h>

Detailed Description

Class MidiPitch is just an int number representing the pitch in a chromatic scale. It is the same as the MIDI key number used in MIDI for representing pitch. It has the following properties:

• Very compact.
• Equal temperament tunning assumed. This implies that there is no possibility to differentiate between enharmonic sounds, for instance, C sharp and D flat.
• It is intended to be used only for sound generation.
• It is usable for sweeps along the equal temperament sounds.
