MIDI Data Format for VOCALOID2 VSTi

いわゆる「Vocaloid2のvsqファイル」の仕様書…と思う。
VOCALOID2製品のマニュアルの巻末に大体ついてるみたい。

基本的にMIDIのデータ形式ではあるものの、普通のMIDI機器での再生はできない。
たとえるなら、「HTMLファイル形式に準拠するものの、機種依存文字だけを使ってるファイル」とか「ページ全体がフラッシュ動画になっててiPhoneで見えない」とかそういう類の準拠の仕方。
拡張するにしてもnote on/note offすら互換性をなくす意味があったのかはよくわからない。

仕様の抜粋

以下は、マニュアルの記述を読んで理解しようと努力した上でまとめなおしたもの。
MIDIのデータ形式を一通り理解して、いわゆる「打ち込み」をやればできるだけの知識があって、VOCALOID2のパラメータを一通り理解してるとどうにか読めるような内容。まだよくわかってないので、記述間違いがあるかも。あと、VOCLAOID1(Kaito/Meiko)関係の知識がないと「何でこんなデータあるの」とかいう疑問が解消されないらしい。

３．NRPN & Data Entry for VOCALOID2
				Most of the VOCALOID2 information is sent to the synthesis engine in combination with NRPN MSB/LSB (Bn 63 / Bn 62) and Data Entry (Bn 06 / Bn 26). Below is a detailed description:
