MIDI Info ObjectMIDI plugin for AviUtl2

For AviUtl2 (ExEdit2). Analyze and visualize MIDI, with a C API that other plugins can use too.

Multiple visualization objects

Text / Graph / Text Scroll / Keyboard / Piano Roll (CPU, GPU, 3D), all bundled in a single .aux2.

MIDI Source shares the parsed analysis, channel colors, and playback time; every object syncs to it.

MidiInfo_GetAPI exposes a stable function table so other plugins can read BPM, time signature, note spans, and more.

Occlusion of hidden same-pitch notes plus early-exit keep rendering light even for extremely dense MIDI.
