Want to get more expression out of your keyboard?
One way is to put it on wheels – as this video of Mark Steiner‘s ‘Wobble Wagon’ demonstrates.
Here’s what Steiner has to say about his controller hack:
First test/proof of concept. As much as I love the QuNexus keyboard, the one thing I thought it would do best is not something it does well… natural pitch vibrato. But I love the pressure per key controlling sound brightness/filter. So I made the Wobble Wagon to add natural, side to side vibrato. It can also have other keyboard types put on it, as the photos show.
More adjustments to come, but this test shows that it can do the natural pitch vibrato. Adding stuff soon to help it return to an accurate center pitch.
