That means it can also run tracks for a professional tour... and your church. Playback is a MultiTrack playback app available for iPad and iPhone. You can use any MultiTrack or CustomMix file purchased from MultiTracks.com, upload your own content using MultiTracks Cloud, and with Playback Rentals you can rent MultiTracks directly in Playback. Playback is a simple, yet powerful player that allows you to edit song arrangements, loop tracks in real time, control via MIDI, and send multiple outputs with MultiOuts and a USB audio interface. Get started by downloading Playback for free and get access to a free song every week through our "Play of the Week" promo within the app. Learn More.
