// Just When I Needed You Most — Randy Vanwarmer
// 91 bpm, 4/4, key A major. Source: mcgill + midi.
// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 6 "Staff-6" epiano1 (copy of ch 5 "Staff-5" pad new age)
// note: Full arrangement: all 49 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(91/4)

// 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 · electric bass finger · "Staff-2"
