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!
