Lead Guitar de-duplication + SOLO tab render

Compares Lead Guitar and Rhythm Guitar onsets in the CLOCKFIXED MIDI to identify where Lead is a copy of Rhythm (candidate for cleanup) vs where it plays a distinct part. Also renders the recovered solo as fretted TAB via alphaTab.

Duplicate bars (safe to drop Lead — 26 bars)

These bars have ≥80% of Lead onsets matching a Rhythm onset within 60ms + same pitch class. Dropping Lead here removes the doubling.

Recovered solo as fretted tab

alphaTab renders the SOLO Guitar Pro file directly. The tab loads client-side from the drwu-htmls route.

Honest read + not done this pass

De-dup analysis: shipped as data + strip + tables. 26 bars are candidates for removing the Lead double.
Actually rewriting the CLOCKFIXED-SOLO.gp with the Lead cleaned is NOT done this pass. GP7 files are zips of tab XML — editing them cleanly needs a dedicated parser (python-guitarpro or manual XML surgery). The audit above tells the human editor exactly which bars to clear.
alphaTab renderer: loads client-side from CDN. If it does not render on your browser, the audit + tables still stand as the analysis output.
