Vocalist wants to trigger some backing vocals
As the subject states, our singer wants to add some vocals that would not be possible with a harmonizer device. It's usually different timing or like an "oooooh" behind the lead vocals.
We've looked at a Digitech Jam Man Solo, or installing Ableton Live on a laptop triggering the sounds with a footswitch.
We all play into a JamHub, if that matters.
What can you suggest?
