Stems mix live in the app and in the browser.
A stem song has up to eight parts, such as click, drums and bass, plus an optional stereo mix. The Android app and any current browser mix the parts live, with on/off, level and pan per stem. Only older browsers fall back to the stereo mix, which the app calls slot 9, Web Playback.
Changing key, tempo or formant while a song plays needs Android, as does hosting Follow for the band. If another device needs to hear a changed version, save it as a new file there. Everything else works the same on whatever device you gig with.

This uses the same version check as the web app. It reads your browser's user agent on this page and doesn't send it anywhere.

At a glance
Current browsers mix. Older ones play the stereo mix.
The browser decides by its version, not by how much memory is free right now. Ordinary stereo songs play everywhere.
| Where | Stem songs | Key, tempo, formant | Follow this Stage |
|---|---|---|---|
| Android app (Android 7 and later) | Mixes stems 1–8 | Live, while playing | Hosts, or follows |
| Chrome, Edge, Brave, Opera 94 and later desktop, Chromebook, Android | Mixes stems 1–8 | Not in the browser | Follows |
| Safari 26 on iOS 26, iPadOS 26 or a Mac | Mixes stems 1–8 | Not in the browser | Follows |
| Any browser on an iPhone or iPad without iOS 26 | Plays the stereo mix | Not in the browser | Follows |
| Firefox, Chrome 93 and older, Safari 18 and older, unknown browsers | Plays the stereo mix | Not in the browser | Follows |
There's no iPhone or iPad app yet. On Apple devices, WotGig runs in the browser.
Apple · iOS 26 & iPadOS 26
On Apple, the OS version decides.
Mixing stems in the browser on an iPhone or iPad needs iOS 26 or iPadOS 26 (Safari 26). That is Apple's OS floor, not a WotGig performance promise. Older iPhones and iPads still open the library, play ordinary tracks, and play stem songs from the stereo mix.
iPhone: A13 Bionic or newer
iOS 26 needs an A13 Bionic chip or newer, which goes back to the iPhone 11 series (2019). A12 phones (iPhone XS, XS Max, XR) can't install iOS 26 and play the stereo mix for stem songs.

iPhone SE

Less battery and memory than the Pro models. A mix may still hitch on long WAV packs.
iPad: A12 Bionic or newer, or any M-series
iPadOS 26 needs an A12 Bionic or newer, or any M-series chip. It drops the 7th-generation iPad (A10 Fusion). Those iPads still open WotGig in the browser and play stem songs from the stereo mix.
iPad Pro

Chrome, Firefox and Edge on an iPhone or iPad don't change any of this. Apple makes those browsers use Safari's engine, so the OS version counts, not the icon on the home screen.
Android, Windows, Chromebook, Linux
Same rule, no chip list.
These platforms mix when the browser is new enough. Beyond that, the processor and memory decide how comfortably a big pack plays.
Android app
- Mixes stems 1–8 on the device (Android 7 and later)
- The stereo mix is for older browsers and is never added to the stem mix
- For a gig: a recent mid-range tablet or better
- Budget phones, 2 GB tablets and a hot stage can hitch or take longer to buffer
Chrome · Edge · Brave · Opera
- Version 94 and later (late 2021) mixes stems 1–8
- Desktop, Chromebook and Android Chrome all count
- Chrome on an iPad doesn't: that's Safari underneath
- Version 93 and older plays the stereo mix
Firefox and others
- Desktop Firefox plays the stereo mix
- Unknown or embedded browsers play the stereo mix
- If there's no stereo mix, the song shows a message instead of playing
Windows or Linux PC
- Use the web app in Chrome or Edge for a live mix
- A recent laptop with 8 GB of memory or more is comfortable for a typical karaoke pack
- Long uncompressed WAV stems still cost CPU and memory
Slot 9 · Web Playback
For older browsers.
WotGig doesn't invent a mix on a browser that can't make one. It plays the stereo mix you attached: one ordinary stereo file, at the same loudness as any other track. The per-stem mute buttons are hidden, because there's nothing to mute.
Attach that file in Song Details, or when you import. Export a songs-only zip only if the stereo mix is there; otherwise export a bundle so the stem files stay with the song.
If the browser can't mix and there's no stereo mix, Stage and the mini player show "Attach a Web Playback file in Song Details to play this song in this browser." The song stays in the library, and charts, lyrics and a silent Stage still work for the band.
The stereo mix is optional on devices that already mix. Attach it anyway if anyone in the band opens the same library on an older iPad, Firefox, or a phone that never got iOS 26.
Caveats
Heat, memory and long WAV packs.
On any device, app or browser, eight stems is real work: decoding plus memory plus heat. A few things are worth knowing before a long WAV pack.
- Memory, not just the chip name. An iPhone 11 can install iOS 26 but has far less memory than an M4 iPad Pro. Eight uncompressed WAV stems can stall a phone or an old tablet, or get the tab closed. Gig-length MP3 or M4A packs are the intended case.
- How many stems are filled, and for how long. Empty slots cost nothing, and four stems cost about half of eight. A three-minute karaoke pack is a different job from a twelve-minute 24-bit WAV.
- Heat and background apps. A tablet in a stand, in the sun, with ten tabs and a maps app open will throttle. Close other apps and keep the set on the device before the gig. Don't rely on a first-time download at the downbeat.
- Codecs. Imports are MP3, M4A, WAV and similar. Safari is pickier than Chrome: a file that plays as stereo can still fail as a stem. If a mix-capable browser can't start the pack, attach the stereo mix or convert that stem.
- No silent fallback when memory runs out. The file that plays is chosen by browser version, not by a live memory reading. A supported iPad that runs out of memory will hitch or fail rather than switch to the stereo mix.
- Need a different key or tempo on the night? That's the Android app. Otherwise, gig on whichever device suits you, and keep the set on it before you leave.
