My wife was in a T40 pop trio (gtr/drm/key>r) using an Apple and Ensoniq to fill out a lot of vocal backups, and string and horn parts.
Would have bugged me too except they are all awesome singer/players.
They did it to save money.
Used to sit in on nights my band wasn't playing.
Playing to a click is fun with a good drummer. Or put the candy on 'hold' and have a "real" band!

Some of those 80s/90s dance hits had smokin' bass parts!
