MusoLoop and Stage Traxx 4 both belong on a gig, but they are built for different jobs. Stage Traxx 4 is a live-performance app for iPad, iPhone and Mac, centred on multitrack backing tracks, lyrics and stage control. MusoLoop is a browser-based song library for the repertoire a band, teacher or solo musician actually uses, including the charts and the tracks.
Stage Traxx 4 is built for the stage rig
Stage Traxx 4 plays up to 32 audio tracks per song, with a mixer, output buses and a separate click. Lyrics and chords auto-scroll with playback, and audio regions let you loop a chorus, skip a bridge or extend an outro while the song is running. A built-in metronome, PDF sheet music, MIDI commands and page-turner or foot-switch control sit in the same setup. Band members can follow lyrics and playback together over Wi-Fi.
There is no catalogue of other people’s songs. You import your own tracks, lyrics and PDFs, and you run the show from the app.
MusoLoop is built around the shared repertoire
MusoLoop keeps the songs you play in one library: lyrics, chords, audio, video, PDFs and notation, including Guitar Pro and MusicXML. Collections and setlists organise that material for rehearsals, lessons and gigs. Because it runs in a browser, a guest or student can open a shared song without installing an app or creating an account.
Backing tracks live on that same song. You can load one mixed MP3, or separate click, cue and instrument stems, and send the click and cues to in-ears while the music goes to the house. On the night, the audience can request songs from the library, including paid requests.
The biggest difference
If the job is a dedicated backing-track rig — many stems, buses, MIDI, regions and a foot switch — Stage Traxx 4 is aimed at that. If the job is keeping every version of a song in one place, and sharing it with a band, a class or an audience, MusoLoop is aimed at that. Backing tracks are one part of the song, not the whole product.
Which approach fits?
- Choose Stage Traxx 4 when: you want a dedicated iPad, iPhone or Mac app for multitrack playback, a click, MIDI and hands-free stage control.
- Choose MusoLoop when: you want a browser library that holds charts, notation and backing tracks together, with guest or student access and audience requests.
They can also sit side by side. Stage Traxx 4 can run the tracks on stage, while MusoLoop holds the charts, arrangements and shared library the rest of the week.
