// 125 bpm, 4/4, key C# minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 3 shamisen (copy of ch 2 pizzicato strings)
// note: Full arrangement: all 14 bars on a 32-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
