Musigana Editing Tools — Pitch, Tempo & Lyrics Editor

Once you start a karaoke project in Musigana, three editing tools let you shape the track to your voice and your words: pitch, tempo, and the lyrics editor. Musigana first splits the song into clean stems — a backing instrumental apart from the vocal — and from there every edit is non-destructive, so you can experiment freely.

Pitch shift: move the song into your key

You can shift the pitch up or down six semitones. Use it to:

• Bring a song that sits too high down into a comfortable range.
• Match a track to an instrument or to another song in a set.
• Transpose a cover without re-recording anything.

Because the shift is applied to the separated audio, you avoid the "chipmunk" artifacts you get when you naively speed a track up to raise its pitch.

Tempo shift: change speed without changing key

Independently of pitch, you can stretch the tempo from 0.5× to 1.75×. Pitch and tempo are decoupled, so:

• Slow a fast passage down to 0.5× to learn it, and the key stays the same.
• Nudge a song slightly faster to tighten a performance.
• Practice difficult sections at half speed, then return to full tempo.

Pitch and tempo are live performance controls — they shape how the track plays back while you rehearse and perform in the app.

Lyrics editor: fix a word, retime a line, rewrite a verse

Musigana auto-aligns the lyrics to the vocal word by word, so each word lights up in time as the song plays. When you want control, the lyrics editor is built for speed:

• Retime word by word when you want a line to land perfectly.
• Rewrite the lyrics entirely — and Musigana keeps your new words locked to the original rhythm, so the timing survives the edit.

For the cleanest result, keep your lyrics accurate and laid out line by line, in the order they are sung — a missing or out-of-order line can push the alignment off. Your lyric edits are saved with the project and baked into the exported karaoke video.

Putting it together

A typical session: drop the pitch two semitones to fit your voice, slow the bridge to 0.75× while you learn it, then tidy the lyrics — retime a tricky line and fix a misheard word. When it all feels right, return to full tempo and export the karaoke video with your synced, edited lyrics.
