// Dimmi dimmi perche — Fiorello
// 98 bpm, 4/4, key F major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 12 epiano2 (copy of ch 11 epiano2); ch 15 voice oohs (copy of ch 16 synth choir)
// note: Full arrangement: all 94 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(98/4)

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

// bass · electric bass pick
