// Always With Me, Always With You — Joe Satriani
// 67 bpm, 6/8, key B major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: bank select 127 on channels 2, 4 is ignored: the parts fit General MIDI, not the Roland MT-32 map it names
// note: Full arrangement: all 75 bars on a 24-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(67/3)

// 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"
