Package apple.avfaudio

Class AVExtendedNoteOnEvent

  • All Implemented Interfaces:
    NSObject
    public class AVExtendedNoteOnEvent
extends AVMusicEvent
    AVExtendedNoteOnEvent The event class representing a custom extension of a MIDI note-on. Using an AVExtendedNoteOnEvent allows an application to trigger a specialized note-on event on one of several Apple audio units which support it. The floating point note and velocity numbers allow optional fractional control of the note's run-time properties which are modulated by those inputs. In addition, it supports the possibility of an audio unit with more than the standard 16 MIDI channels. API-Since: 16.0

        initWithMIDINote:velocity:groupID:duration Initialize the event with a midi note, velocity, instrument and group ID, and a duration.
        Parameters:
        midiNote - The MIDI velocity represented as a floating point. Range: Destination-dependent, usually 0.0 - 127.0.
        velocity - The MIDI velocity represented as a floating point. Range: Destination-dependent, usually 0.0 - 127.0.
        groupID - An index indicating the AudioUnitElement within the Group Scope which should handle this event (see AudioUnitElement). This normally maps to a channel within the audio unit. Range: normally between 0 and 15, but may be higher if the AVMusicTrack's destinationAudioUnit supports more channels.
        duration - The duration of this event in AVMusicTimeStamp beats. Range: Any nonnegative number.

        initWithMIDINote:velocity:instrumentID:groupID:duration Initialize the event with a midi note, velocity, instrument and group ID, and a duration. This initializer is identical to initWithMIDINote:velocity:groupID:duration with the addition of an instrumentID parameter which will allow for the possibility of an externally-created custom instrument. If this initializer is used, instrumentID should be set to AVExtendedNoteOnEventDefaultInstrument for now.
