// 95 bpm, 4/4, key E minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 2/4 at bar 34, 4/4 at bar 35, 2/4 at bar 46, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: bank select 127 (Roland MT-32 map) read through the MT-32 patch table: ch 8 "Triangle" Triangle -> tinkle bell
// note: Full arrangement: all 115 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
