ABでMIDI入力を受けるには
どのようにしたら良いのでしょうか。
ヘルプを読んではみたものの
MIDIの再生についての記述はあったのですが
肝心のMIDI信号の入力については全く分かりませんでした
ノートオンとノートオフが分かればよいのですが...
どなたかご教授願います。
MIDI入力を受けるには
Re: MIDI入力を受けるには
どの程度ものが作りたいのかよく分かりませんが、ノートオン・オフを知りたいというのであれば下記のAPIを使用すればできます。> ABでMIDI入力を受けるには

ただ、wave～関連APIでの録音法とほとんど変わらないらしいという情報は手に入れています。
時間があればサンプルを乗っけに再度来ることもあるかもしれませんが、こちらにテストする環境がないので動作は保障できません。
※シンセでも買ってみるかな。。。

サンプルを作ってみたんですが、> 返信ありがとうございます。

先にも書きましたとおり、当方にはテストする環境が無いので、
そちらでぶっつけ本番となります。
あと作成したのはAB4.12ですので、
もし、別のバージョンで作成されているようでしたら
連絡してください。
サンプルはMIDI入力から読み込んだデータを
オウム返しにパソコンのMIDI出力から出すものです。
サンプル中ではデバイスのオープンにMIDI_MAPPERを指定していますが、
実際にはそのようにしないでください。
出力デバイスと入力デバイスが被ってしまうとどうなるか私には分かりません。

ウィンドウモードでプロジェクトを作成（名前はmidiin）して
コマンドボタンを２つ貼り付けるだけで動くようにしています。
CommandButton1が入力開始でCommandButton2が停止です。
