OffgridStem Now Separates 6 Stems Instead of 4

OffgridStem's latest update just passed App Store review, and it changes what the app can actually do: separation has gone from 4 stems to 6. Piano and guitar now come out as their own stems, instead of getting bundled into a general "other instruments" track.

What's new

OffgridStem now separates a track into: vocals, drums, bass, piano, guitar, and other instruments — six stems from a single pass, still entirely on-device. If you've been isolating piano or guitar parts by ear, or fighting with a generic "instrumental" stem that has both blended together, this update is for you.

Same on-device architecture

Nothing about how the app handles your audio has changed — separation still happens entirely on your iPhone, with no upload, no account, and no subscription. The update is purely about what the model can isolate, not how it processes your data.

Frequently asked questions

How many stems does OffgridStem separate now?

Six — vocals, drums, bass, piano, guitar, and other instruments, up from four in the previous version.

Do I need to pay again for the 6-stem update?

No — it's a free update. Update through the App Store if you already own OffgridStem, or download it for the first time to get six stems from the start.

Does the update change how OffgridStem handles my audio?

No — separation still happens entirely on-device, with no upload, no account, and no subscription. Only what the model can isolate has changed, not how it processes your data.
