### 1/5 — 開けない

*2024-04-14*

今まで問題なかったのですが、最近開けないMIDIが出て来ました。
前から入っているものは聞けますが、新しく共有したものが開けないです。他のアプリ使ってる人は皆んな開けてるので、アプリの問題かな？と思ってます。
何とかして欲しい…

### 4/5 — 総じて大変良いです。

*2024-01-23*

楽器のマイナスワン練習のため、iPad miniにて、当アプリでMIDIファイルを読み込み、ヤマハのMD-BT01を介して音源を鳴らしています。
外部サイトで購入したXG規格のMIDIファイルも適切に再生されていて満足しています。
一点、各チャネルのミュート、ソロ機能が働かず、そこが残念なところです。
（iPad OSは17.1にしています）
あとは、以下ができるようになると、うれしいかも。。。
・テンポをパーセントではなく、数値で変更
・AB間リピート

### 3/5 — Muting channel does not mute core-midi

*2022-09-26*

Muting a channel does not mute core-midi output. It only mutes the channel audio of IOS device running it. It this a bug?

### 3/5 — プログラム番号

*2021-09-12*

ループさせて、2回再生したときは、問題ないのですが、 一部のGM配列用のプログラムチェンジが、 一周めに反映されず、全部ピアノの音になる不具合があります。 例、ジョンウィリアムズさん公式で配布してるSMFファイルや、私のつくった、Extended MIDi mIxer for Java(OSDN)のサンプルSMFなどです。あと、表示ですが、音色名、番号、音量が表示される(16箇所)モードが欲しいです。それから、8曲以上ロードできません。一覧にでてこなくなりました。いまでも大変ありがたいですが、、今後に期待してます。

### 1/5 — Changes all your set instruments to piano

*2021-09-12*

This is a useless App in dire need to be removed from sales. Even if you have dedicated uncounted hours or days to your midi files, this App will play all the tracks in your file as Grand Piano. Even if you fix all the instruments in the song through this App, there is no way to save the corrections and if you replay it it will come back as Piano all of the instruments. You can’t be doing this in a live gig.
