MIDIOUTCAPSA
構造体サイズ=各フィールドのバイト数(x64/x86 で異なる場合は x64/x86 と併記)。x64/x86 列=フィールドのバイトオフセット(HSPで dupptr / lpoke / wpoke 等に使用)。
フィールド

| wMid | WORD | 2 | +0 | +0 | デバイス製造元(メーカー)ID。 |
| wPid | WORD | 2 | +2 | +2 | デバイス製品ID。 |
| vDriverVersion | DWORD | 4 | +4 | +4 | ドライバのバージョン(上位8bitがメジャー、下位8bitがマイナー)。 |
| szPname | CHAR | 32 | +8 | +8 | デバイス製品名(ANSI、固定長配列)。 |
| wTechnology | WORD | 2 | +40 | +40 | デバイスの種類(MOD_MIDIPORT/FMSYNTH/MAPPER等)。 |
| wVoices | WORD | 2 | +42 | +42 | 同時発音可能なボイス数。内蔵シンセの場合に有効。 |
| wNotes | WORD | 2 | +44 | +44 | 同時に発音可能なノート数。 |
| wChannelMask | WORD | 2 | +46 | +46 | 応答するMIDIチャンネルを示すビットマスク(各bitが1チャンネル)。 |
| dwSupport | DWORD | 4 | +48 | +48 | サポートする機能を示すビットフラグ(MIDICAPS_*)。 |

}HSP用 定義
HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。
; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; MIDIOUTCAPSA サイズ: 52 バイト(x64)
dim st, 13 ; 4byte整数×13(構造体サイズ 52 / 4 切り上げ)
; wMid : WORD (+0, 2byte) wpoke st,0,値 / 値 = wpeek(st,0)
; wPid : WORD (+2, 2byte) wpoke st,2,値 / 値 = wpeek(st,2)
; vDriverVersion : DWORD (+4, 4byte) st.1 = 値 / 値 = st.1 (lpoke/lpeek も可)
; szPname : CHAR (+8, 32byte) varptr(st)+8 を基点に操作(32byte:入れ子/配列)
; wTechnology : WORD (+40, 2byte) wpoke st,40,値 / 値 = wpeek(st,40)

; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
