The four notes
A video editor made a campaign film with a song from Foundry. The client approved the song and sent four notes: new words in the last chorus, more punch in the bridge, a minute more music because the video got longer, and a second version for the next ad. You make all four changes and keep the song they approved.
The editor and the client are made up. The song "Golden" and every fix you hear in the video are real, made in Foundry.
1. New words in the last chorus
The last chorus sings "We were golden all summer long". The client wants their campaign line: "We stay golden all year long".
Open the Patch tab and choose Full, the kind of Patch that can change words. Pick the song as the source. On the timeline, drag across that one line: the green selection is the only part Foundry touches.
In the lyrics, change that line and leave every other word alone. Tick Preserve surrounding sound, so everything around the line stays as it was. Then press Create.
In the video the new line came back after about two minutes, on the first try. Same singer, same mix. The fix lands on the timeline as a new clip, and the approved song underneath stays untouched. If a take ever misses, press Create again.
The same move works for a brand name in a jingle or a date in an intro.
2. A bridge with more punch
Same setup: the Patch tab, Full, and the song as the source. Select the bridge and leave the lyrics as they are. This time, type the sound you want into the Style Override box. Here is the direction used in the video:
Driving pop rock, strummed electric guitars, full live drums, and the band plays louder with every line.
Press Create. Same words, same singer, new energy. Foundry follows your direction but keeps the bridge inside the same song, so it still fits everything around it.
3. A minute longer
Pick the Extend tab and select the song as the source. Write the words for the new part. In the video that is one more verse and a last chorus with the campaign line. The new words decide how long the new part gets.
Press Create. Foundry continues the song and places the new part right after the old ending. In the video, 1:35 became 2:45, and the last words she sings are the client's line.
Tip. Extend picks up where the song stops. It works best on a song that ends right after its last chorus, like the 1:35 version of Golden in the video. A song that already closes on a finished outro has little left to continue.
4. Combine the fixes with Overrule
Each fix sits on the timeline as its own clip, right where it belongs. Switch on Overrule, the little shield in the track header of each fix. While that clip plays, it replaces the approved song underneath, so the song and all its new parts play as one.
5. A second version for the next ad
Switch the music model to Foundry Music v4, Foundry's own fast engine. Keep the song's words and style, press Create, and you get a fresh take of the same song.
Then use Export Audio for the finished song and the new version, and send both back.
Quick recap
- Patch changes the words of one line.
- Patch with a style override changes the energy of a section.
- Extend makes the song longer.
- Overrule combines the fixes with the approved song.
- Foundry Music v4 gives you a second version.
Let your AI agent do it
Every step works by hand in the app, as the video shows. On the Professional plan, your own AI agent can run the same steps for you. Foundry includes instructions for agents inside your Foundry folder: documentation\agent_skills.
Which plan you need
Patch and Extend are included in the Creator plan, with commercial use for your own projects. If you deliver music to clients, that is the Professional plan: it is made for client work and adds automation and your own AI agent. See the plans.
