Make your first stem mix

1. Sign in and open Studio.
2. Choose Start a mix.
3. Click the session title to give the song a name. Press Enter to save and leave the field.
4. Drag your stems into the upload area, or choose Add stems.

You can drop a whole batch at once. Upload rows appear with progress, and you can add another batch while the first is uploading, within your track allowance.

1. Wait for upload/preparation to finish.
2. Check the instrument dropdown on every row. Filenames help select these automatically.
3. Press a row's preview button if you need to identify its audio. Raw listening does not require a completed mix.
4. Review the Mix profile dropdown. Start with Clean instrument profiles if you are unsure.
5. Exclude duplicate sum or alternative tracks. Use mute for parts you do not want included.

Level sliders and FX controls become available after a stem has been mixed. This lets you establish the automatic mix before fine-tuning it.

1. Choose the gold Mix All button beside the Mix profile dropdown.
2. Follow the status as stems mix and the whole song is balanced.
3. Wait until no tracks are processing and the player returns.
4. Press Play at the bottom to hear the mix. MP3 previews preload; the player shows loading progress if audio still needs to arrive.

You do not need to press a mixing button once per stem. After the first mix, the batch button becomes Remix Changed.

1. Adjust a track's level or open FX for EQ, compression, stereo or reverb.
2. Wait for All changes saved. Most channel effects are included when mastering; instrument, sound-profile and noise-cleanup changes need a new mix pass.
3. Choose Mastering options if you want a different mastering profile, tone or loudness target.
4. Choose Master song and watch its progress.
5. When finished, listen to the master and compare it with the pre-master mix.
6. Choose Download master WAV. Free accounts can buy a $5 pack of three master downloads; Pro includes unlimited downloads plus mix and stem WAVs.

Keep a downloaded backup, particularly on Free: sessions expire after 24 hours of inactivity.
