One REALLY BAD thing about PSR harmonizers is that there is no light indicating whether it is engaged.
One great thing about Korg PA4X harmonizer is that you can assign Harmony Volume to a footswitch and, with a momentary pedal, harmonizer only engages while you hold the pedal down.
It actually is always engaged, but the pedal reduces the harmony volume to zero, instantly.


All valid good points Don. It's a shame so many players don't sing or won't even try, or give some Bs excuse that "you don't want to hear me sing" "I'm tone deaf" or some other ridiculous excuse,.....
that said it's a feature that is never used or considered on an arranger KB.
