Tuning. Editorial C-major 12-TET projection. The source lets every pattern use interchangeable sampled tunings, so it defines no single pitch map. This audition-only projection orders B0–B8, L1–L7, then R1–R10 on C-major steps from C2. Frequencies are unmeasured and null; the MIDI notes do not claim acoustic fidelity to any mbira.

Rights. Pattern from the mbiramachine catalog by GitHub user muratgu, pinned at commit 2ceeda51540fc31c61d1356bd02bd3a81e5c105f. Direct written permission from muratgu authorizes the following: Redistribution, adaptation, and public playback of these catalog patterns in this project. Cultural access is unreviewed: Direct written permission from the catalog creator covers the source artifact and this adaptation, not cultural authority over the underlying Shona repertoire.

Adaptation. Parsed catalog.dat cells one-for-one. B and L keys route left; R keys route right. Simultaneous tokens remain chords, and empty cells, including terminal rests, remain in the cycle. Hosho phase stays in the source manifest and is omitted from melodic playback. MIDI uses an editorial 12-TET projection with no measured frequencies.

Evolution. Research model: one-hand phrases are checked against pinned sibling patterns and seam-ranked before growth or release. It does not model a second performer or reproduce a particular player.
