Adaptation. Reduced to the first 48-pulse cycle; MIDI note, velocity, register-track, and duration data are retained. Track names are descriptive additions, and playback is slowed from the source artifact’s 150 BPM to 100 BPM for study. The source provides no performer, teacher, or transmission lineage.
