// Felicidade, que saudade de voce — Zeze di Camargo
// 78 bpm, 4/4, key F major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (3/4 at bar 1, 4/4 at bar 2, 2/4 at bar 34, 4/4 at bar 34, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: sustain pedal (CC 64) lengthens the held notes
// note: Full arrangement: all 89 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): guitar program 30.
setcpm(78/4)

// 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.
