SongCoach v1.2.0

SongCoach v1.2.0

Hear the singer, isolate the band, and mark up your practice — plus a way to
bring your whole back catalogue up to speed.

🎤 A vocals stem — now four stems per song

Every song now separates into four rows instead of three:

• FULL SONG (reference mix),
• DRUMS — the kit, solo,
• VOCALS — the voice, solo, and
• BACKING — bass, keys & the rest, with drums and vocals removed.

Blend them with the per-stem faders. To play along, just drop DRUMS out of
the mix and you've got the whole song minus the kit — vocals and all.

♻️ Reprocess — upgrade older recordings to four stems

Recordings you made before the vocals stem existed still show three rows. Bring
them up to date without re-recording:

• Per song — open its player and hit the reprocess button (the
  circular-arrows icon, next to edit and delete). It re-separates the song and
  adds the vocals + backing stems. Your markers are kept.
• Whole library — run python -m songcoach.reprocess from the source tree to
  upgrade every recording at once, one at a time (--force to redo ones that
  already have vocals).

Reprocessing works from the full-song audio each recording already keeps, so
nothing needs re-capturing.

📍 Waveform markers

Annotate a recording so you can find the good bits fast:

• Click the flag icon in the player, then click a waveform to drop a marker —
  a line spanning all the stems with a small "i" badge.
• Give each one a name ("guitar solo", "big fill", "key change"). Placing one
  shows the exact timestamp, and while placing, a live time tooltip follows your
  cursor so you can land it precisely.
• Click a marker's "i" to rename or delete it. Markers are saved with the
  recording and survive edits and reprocessing.

Polish

• The four stem rows now sit on the clean light panel, with each stem's fader and
  toggle tinted its channel colour.
• Apple Music mode's session panel gained a refresh control so finished songs
  show up in the library without relaunching.
