(注意：iPhoneで確認したら、音が出るまでに、0.5秒ぐらいラグがある)

単音を出す方法

  1. 適当なGameObjectを作成し、MySyntheStationを設置
  2. 以下Keyboard.csをカスタマイズしたOneSound.csを作成

呼び出し側 

MySpace.Sample.OneSound oneSound = GameObject.Find("MySyntheStation").GetComponent<MySpace.Sample.OneSound>();
oneSound.KeyDown(int.Parse(keyNo));

ライブラリ側

音色変更

ToneData変更は以下の通り 

using MySpace;
string toneData = "@ct8[0 0 0 [31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 31 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ] env[0 1 0 31 9 15 0 5] lfo[0 127 0 0 31 0 0 0 0]]";
var tp = new Synthesizer.MySynthesizerPM8.ToneParam(toneData);
Synthesizer.MySynthesizerPM8.ToneParam param = (Synthesizer.MySynthesizerPM8.ToneParam)tp.Clone();
var ts = new Synthesizer.ToneSet();
ts.Add(param.Clone());
syntheStation.Synthesizers[PortNo].Channel[ChNo].ProgramChange(ts);
