ios - AudioKit:如何更改使用 AKMIDIEvent 播放的音符的音量或音调？

Question

我正在使用 AudioKit 播放音符

midi.sendEvent(AKMIDIEvent(noteOff: noteToPlay, velocity: MIDIVelocity(0), channel: MIDIChannel(0)))

是否有一个命令可以用来改变使用 AudioKit 播放的音符的音量或音调？

Answer 1

经过一些搜索，我发现确实是 CL 提到的 Controller 更改事件完成了这项工作。

所以考虑到命令是

/// Modulation Control
case modulationWheel = 1
/// Breath Control (in MIDI Saxophones for example)
case breathControl = 2
/// Foot Control
case footControl = 4
/// Portamento effect
case portamento = 5
/// Data Entry
case dataEntry = 6
/// Volume (Overall)
case mainVolume = 7
/// Balance
case balance = 8
/// Stereo Panning
case pan = 10
/// Expression Pedal
case expression = 11

我要打电话

midi.sendEvent(AKMIDIEvent(controllerChange: 7, value: MIDIByte(volume), channel: MIDIChannel(0)))
