Each musician's chart, sound and mix
Central Usage is the app for the people on stage. Each musician and singer gets their own chord chart, the lyrics, their instrument sound and their own in-ear mix. It works at church and at home.
Each key works on two devices, so a player can have one at church and one at home.

What Central Usage does

Central Pedal
The pedal at the worship leader's feetA floor unit that plays your pads and multitracks, shows the chart and lyrics, and runs a looper and a guitar or keys rig. It has 12 footswitches, knobs, a touch screen and two HDMI ports. We build and test each one, and it arrives ready to play.

Central Control
The desk runs the whole serviceCentral Control runs the room from the desk: lights, lyrics, slides, cameras, the stream, in-ears and the run sheet. If you have more than one computer back there, give each one its own jobs and they work together.
