// Adagio for Strings, Opus 11 — Barber Samuel
// 67 bpm, 4/4, key A# minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: ch 1 "1stViolin" named as a string part, played on violin (its piano patch is not one); ch 2 "2ndViolin" named as a string part, played on violin (its piano patch is not one); ch 3 "Violas" named as a string part, played on string ensemble 1 (its piano patch is not one); ch 4 "Cellos" named as a string part, played on cello (its piano patch is not one)
// note: Full arrangement: all 145 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(67/4)

// 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.
