Stems or the full multitrack, every file from the same start point, plus MIDI files if you have them.

In the notes, name the sounds you want replaced or tightened, and add a released song as a reference.

Zip the session together with a demo mix and drop it into the uploader.

$100 per song, 2% off per song when you order several. Pay by card.

We replace and align the parts and send them back in 2–3 days per song, with 6 revision rounds included.

Edited stems as WAV files, ready for mixing.
We replace weak sounds in your production (kick, snare, bass, hats) with better ones from pro libraries, and tighten the timing of guitars and drums. The arrangement stays yours; only the sound quality changes.
Make an Order*Price depends on the project size — calculate your exact price on the order page. Not happy with the result? See our refund policy.
Export the session as stems or a multitrack and add a demo mix. If you have the MIDI files, send them too. Tell us in the notes which sounds bother you. You get edited stems back as WAV files in 2–3 days per song, with 6 revision rounds included. Music Editing is $100 per song.
If we are mixing the song anyway, add Music Editing on the Mixing or Complete Mixing and Mastering form for $50 per song. Order it on its own when you mix yourself. If the problem is the vocal, you need manual vocal editing instead. If the song is already mixed and you want to swap a sound, that is stem replacement.
Some problems can’t be fixed in the mix because they are in the production itself: a thin kick sample, a cheap preset, a guitar part that drifts off the grid. You could ask your beatmaker to redo it, but that can take a long time.
Music Editing fixes this before the mix. We replace weak samples (kick, snare, bass, hats) with similar, better-sounding ones from high-quality libraries such as Omnisphere, Spire, Splice and KSHMR, and align the timing of guitars and drums. We don’t rearrange: the parts stay the same, they just sound and sit better.
Export stems or the multitrack, zip them with a demo mix and upload the zip on the order page. Choose the number of songs, describe what you want replaced in the notes, and pay at checkout.
Yes, if you have them – that will be perfect.
No, we improve the sound, not rearrange it.
A stem is a group of related tracks bounced down to a single file – all the drums as one stem, all the backing vocals as another. A multitrack is every channel exported on its own: kick, snare, bass, piano, lead vocal, background vocal and so on. For mixing we want the multitrack; for stem mastering we want stems.
First of all, export your demo mix.
Then you need to export stems from your DAW. We have a list of video manuals:

Pro Tools – https://www.youtube.com/watch?v=iFC-_U_Qp7U&t=23s
Garageband – https://www.youtube.com/watch?v=M0vCDyqqM6g&t=1s
Ableton Live – https://www.youtube.com/watch?v=OiN_ovVsp40&t=22s

Cubase – https://www.youtube.com/watch?v=OSwd1f81ZD0&t=31s
Reaper – https://www.youtube.com/watch?v=KLltl2nvsR8&t=1s
Double check your audio files before uploading. Reload them into a new Session/Project, checking that they are in the correct placement and length.
Finally zip your files.
Yes, that would be perfect! But no problem if you don’t have it.
No. The demo shows us the arrangement and the sounds you chose. For the sound you want to end up with, send a released song.
You may send us a reference track to show us the sound you like. If there are no reference tracks – no worries, we will pick up something similar to your song.
Six, included. If a replacement kick turns out too bright or too heavy for the song, tell us and we try another one. If revisions start going in circles, we say so before quoting anything extra.
Any genre. In electronic and hip-hop productions it is usually the drums and bass that get replaced; in band recordings it is more often the timing of guitars and drums.
We are based in Rubí, Barcelona, Spain, and our engineers work remotely from a few countries. It is always the same named people, not a pool of freelancers.
Yes. Each song in the order takes 2% off the price, so 5 songs save 10%. The order form applies it for you.
Of course. Ask in the live chat on the site or email info@majormixing.com.
A named engineer listens properly and writes back with exactly what is holding the track back and what to do about it. Free, always — no card, no order first, and no obligation to use us afterwards.
