// Taurus II — Mike Oldfield
// 50 bpm, 4/8, key E major. 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 (4/8 at bar 1, 13/8 at bar 123, 7/8 at bar 153, 4/4 at bar 154, ...) are rendered on a constant 4/8 grid of one bar per cycle
// note: Full arrangement: all 218 bars on a 32-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(50/2)

// 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.

// chords · pad poly · "Mike"
