It’s a bit like a dancefloor for your fingers.
I’m probably misunderstanding what it does, but it looks like the perfect instrument for someone who’s really good at tapping. As it happens I’m very good at tapping so the Novation launchpad is probably what I should be asking for, for Christmas this year. You can read all the blurb about it on Ableton’s website but it doesn’t really do it justice.
Groovy.
