### 3/5 — ファイルアプリ対応希望

*2021-05-07*

「iOS用MIDI数値入力アプリ」と伺ってダウンロードしました。 

他のアプリと差別化が図られた内容で、一般受けこそ難しいかもしれませんが、私は支持したいと考えています。 

現時点で要望が2つあります。 

1つは、「ファイル」アプリ対応です。
 PCを所持して作曲をされている方は言わずもがな、iPhone/iPadで制作を完結させている方にも使いやすくなるのではないでしょうか。 
私自身も、自分で打ち込んだ曲を他のMIDIプレイヤーアプリで再生することがよくあります。
その際に「ファイル」アプリから共有できると助かります。 もしそれが叶わなくとも、書き出し時に共有メニューを開く仕様に変更してくださるだけでも構いません。 

バンクセレクト対応です。
せめてプログラムチェンジにだけでもこれが付いていると、GS・XGユーザーの方にも使いやすいものになるでしょう。
このアプリをより多くの方に使っていただくためにも、更新お願いします。
