The solo test.

Most exports fall apart the moment the singing stops. Ours don't.

NEON LIGHTS ARE CALLING—

guitar solo — nothing moving on screen

  • One line hangs through the entire guitar solo
  • The singer guesses. The viewers bounce.

next: And the rhythm takes control…

  • Clean BREAK banner plus a countdown back in
  • The room breathes. The singer lands the re-entry.

First-export quality isn’t a render setting — it’s pacing that respects the song

See it sync

Same song. Same line. Different timing.

Scroll to sweep the divider. Left of the line is a generic word-timer, right of it is the D107 proof.

The cue lands where the singer breathes, not where the vowel peaks

How it works

Six steps. No timeline degree required.

From raw audio to a video you'd actually upload — in one sitting, on your machine.

01

Drop the song

mp3 or wav, straight from your drive. Nothing uploads, nothing phones home.

02

Paste the sheet

Your lyrics with V1 / V2 / CHORUS chips. Plain text in, structure out.

03

Align to THIS audio

Tap lines in time with your recording. We never stamp some LRC we found online.

The whole point
04

Proof it

Frame-accurate previews of every section before you commit to a render.

05

Dial the look

Fonts, colors, second-singer lanes. The neon stage preset ships included.

06

Export YouTube MP4

Crisp 16:9 render, ready for upload — or the bar's big screen tonight.

Who it's for

Three stages. One tool.

Same Builder, same export — tuned for the room you're playing to.

YouTubers & channels

Sync that survives a full watch, a thumbnail frame that sells the click, and an MP4 that's upload-ready the second it renders.

Publish tonight

Bars, hosts & churches

Fast, readable, fully offline. One click and it's playing on the big screen — no Wi-Fi roulette at 9pm.

One-click play

Teachers & vocal coaches

Verse/chorus chips and second-singer lanes, with zero clutter. Students read structure, not noise.

Clean by default

Under the hood

Builder does the work. Copilot lends a pen.

One product, two parts — and the free part is the one that matters.

FAQ

Asked before buying.

Rights, offline use, credits, refunds — the short answers.

Yes — to whatever you put in. D107 syncs a lyric sheet you supply to audio you supply. Use your own recording, a licensed instrumental with sync/YouTube rights, or public-domain material. D107 never downloads, strips or generates songs, so nothing in the export is there that you didn't bring.
