This little theramin is so cute and has so many great features, whether it be a variety of sounds, or effects and quantizing.
This last one is the big feature. In smooth frequency (original) mode it's hard to land on the right note in tune if you want to use this for anything more than just wailing Whole Lotta Love sounds. So you can turn on quantizing which "snaps" to the next note in a pre-define scale. I don't understand the names of these scales (Mixy-dixylothian?? No idea; ask Steve Vai) but I do appreciate being able, out of the box, to play tuneful things with this.
Not only does it snap to notes, you can even fine-tune the degree to which it snaps, giving you a little, *literal* wiggle room for wiggling your hand and giving the notes some vibrato.
This is a serious instrument and a cool party play-piece at the same time. Anyone can sound good on it, or you can "go pro" and play it like a boss. Brilliant fun.
