The Playback app by Multitracks is one app every church should look into to enhance their worship services. Live music in churches nowadays have a new sound in which many songs are songs written and sung by other churches. Many of these new songs are available on Multitracks, a music service that supplies the songs tracks in stems, click, guide, and more. Playback is made by Multitracks and is a very great app to harness the power of Multiracks for live music. I know, many churches have their way of using stems and click tracks, such as Ableton Live and other apps. However, Playback works seamlessly with Multitracks and is very flexible in many ways.
