// Fantasia super 'Valet will ich dir geben' BWV 735 — J. S. Bach
// 72 bpm, 4/4, key Bb major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/4 at bar 1, 4/4 at bar 2) are rendered on a constant 4/4 grid of one bar per cycle
// note: ch 4 "Organ" named as an organ, played on drawbar organ (its trombone patch is not one)
// note: duplicate parts dropped: ch 4 "Organ" drawbar organ (copy of ch 2 "Organ" church organ)
// note: Transcription provider: pdmx. https://musescore.com/score/5696479; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 66 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
