    "First 32 quarter-note beats with nearest-sixteenth attack quantization. Preserve percussion attacks on MIDI channel 10 as a fourth ensemble voice.",
    "Transpose each melodic source to tonic C using a pitch-class histogram estimate; retain its major/minor intervals. Fold bass/chords/lead into stable registers. Preserve at most 1 bass, 3 comping, 1 lead and 3 drum attacks per frame.",
    "Each mix learns a rotating pair from its station pool with first-order ensemble/rhythm and first-order harmony. Append the first two observations as an authored loop seam. Seeded WFC generates sections; it does not shuffle prerecorded songs.",
    "Station tempo, synthesizer timbres, stereo echo, instrument envelopes and track titles are authored arrangements. Source MIDI durations, programs, velocity and tempo automation are not reproduced."
