# marimba — investigative piece for the marimba synth.
#
# Key: C major, A natural minor pentatonic relative (C D E G A) with
# brief F naturals as passing tones. Tempo: 96 BPM (60/96 ≈ 0.625 s
# per beat). Eighth = *0.5, quarter = *1, half = *2, dotted-half = *3.
#
# Lane intent: each section foregrounds ONE preset so the synth's
# range is audible from the first listen — not a complete song, an
# investigation.
#
#   intro      → rosewood lead alone, mid register, classic warmth
#   bass-walk  → bass preset under, sparse low quarters
#   staccato   → hard-mallet preset, rhythmic 16ths, no resonator
#   roll       → roll preset on held octaves, single line on top
#   tutti      → all four layered for the final cadence
