0.6.7 — Improved supplied lyric alignment and EASY arrangements

• Vocal separation is used as the default path for singing analysis. Saved separation results and analysis caches are reused.
• The analysis start flow distinguishes supplied lyrics, automatic lyric recognition, and instrumental music without vocals.
• Supplied lyrics are compared with short audio segments to improve timing alignment.
• Lyrics that could not be time-aligned are managed separately from the intro.
• Originally detected chords and EASY arrangement results are managed separately.
• EASY prioritizes one chord per estimated bar and applies post-processing that retains changes confirmed repeatedly, such as two-beat changes.
• Chord detection uses the original audio. Vocal and MR separation is used for lyric alignment and playback.
• The supplied lyric alignment improvements in this version are separate from the automatic recognition improvements for analysis without supplied lyrics in 0.6.8.

General information

• Lyrics, chords, meter, and start times are automatically estimated. Lyric recognition and alignment errors may remain.
• Existing saved projects do not automatically change to use newly extracted results. Reanalyze the audio when needed, or use the lyric addition and reanalysis feature in 0.6.9.
• Close LUA Music Studio before installation.
• Component-based updates and a model reuse strategy are planned separately, targeting an actual release around 0.7.0.
