uint16 noteID
A unique ID.
bool isValid() const noexcept
Checks whether the MPE note is valid.
KeyState
Possible values for the note key state.
MPENote() noexcept
Default constructor.
This is a base class for classes that perform a unit test.
uint8 initialNote
The MIDI note number that was sent when the note was triggered.
bool operator==(const MPENote &other) const noexcept
Returns true if two notes are the same, determined by their unique ID.
bool operator!=(const MPENote &other) const noexcept
Returns true if two notes are different notes, determined by their unique ID.
double totalPitchbendInSemitones
Current effective pitchbend of the note in units of semitones, relative to initialNote.
uint8 midiChannel
The MIDI channel which this note uses.
This struct represents a playing MPE note.
double getFrequencyInHertz(double frequencyOfA=440.0) const noexcept
Returns the current frequency of the note in Hertz.
This class represents a single value for any of the MPE dimensions of control.
