Kemper Player for worship music? Can it do ambient and PADs?

Sorry, I did my first (and deleted) answer with the stage in mind. But now to the Player. Yes, there are limitations, but the reverb type "Easy Reverb" provides a pad reverb, an Aftermath, both are good starting points for ambient sounds. There are also stereo dotted ping pong delays. You could find some worship-ish sounds in the player.

I often play at the church with my kemper stage, both electric and acoustic guitar, but not typical worship.

I do it almost every Sunday. Look at the free presets at Tone Junkie for starters.
