Multitracker is a live player that allows you to play multiple audio files and midi files comfortably and flexibly with the help of playlists. If a USB audio interface is connected to the iPad, the audio tracks (stems) of a song can be routed to any of the outputs of the interface. At the same time, the headphone output can also be used as an additional routing destination, so that you have two additional channels available. To play midi songs, Multitracker provides a midi player that allows each MIDI track to be assigned to any existing Midi device (whether via USB or iPad instrument such as Sound Canvas). Of course a midi song can be played in sync with audio tracks. If necessary, a metronome with 9 different click sounds and freely selectable time signature can be added to your song or be played alone. It has never been easier to play multitrack and midi songs on stage!

Verdict

The call

The clearest difference is in-app purchases: Sunday Keys at none against Multitracker's 4. Sunday Keys also leads on update cadence (every 3 weeks vs every 2 months). Multitracker's advantage is review sentiment (83% vs 71%) and iOS requirement (9.0 vs 15.0). On price, rating, ratings volume and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sunday Keys holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 145 and 115 respectively. Written reviews complicate that: 83% of Multitracker's written reviews are positive against 71% of Sunday Keys's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Multitracker ships an update every 2 months, Sunday Keys every 3 weeks. The most recent releases landed on October 3, 2026 and October 9, 2026 respectively.
