// L'immenso — Amedeo Minghi
// 53 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/4 at bar 1, 4/4 at bar 2) are rendered on a constant 4/4 grid of one bar per cycle
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 5 string ensemble 2 (copy of ch 1 piano)
// note: Full arrangement: all 59 bars on a 32-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(53/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · "a, b" plays two voices at once · [...]/2 spreads a riff over 2 bars.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
