If yes, how? I'm looking for tips.

I don't see a physical on/off button for it, so, how do you perform with it?.

Thanks

Hi ViLo...I don't use the harmonizer for vocals...I use it to process my mini synth...but, there is a great article on PSR-Tutorial, by a real pro, Dan Rymut (aka "big741") that will probably be a good help to you.

You can find it here:

Thanks a lot!!

When I had one, I assigned the vocal harmonizer on/off to a footswitch.
