// Midnight at the Oasis — Maria Muldaur
// 105 bpm, 4/4, key Eb major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 5 "Marimba" marimba (copy of ch 8 "Clavinet" clavinet)
// note: Full arrangement: all 90 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(105/4)

// 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.

// bass · fretless bass · "Fretless Bas"
