So following my final post and the videos of our final demo, it seems that the Joytone made its way into some blog posts and podcasts! I've collected some of the links with some nice quotes below. Also I dug up some more demonstration videos!
An interview with David and I on the RasPi Today podcast (featuring a live demo!):
"...this dynamic duo have created an entirely new kind of electronic musical instrument designed to allow the player to be more expressive with a single key than almost any other kind of instrument on the market."
"I’ve a particular soft spot for music projects, and this is one of the most exciting I’ve come across so far."
"As for the sound, the Joytone is a burbling synergy of synths and sounds a lot like a heavily modified electronic organ. This is quite possibly the most emotive a Raspberry Pi or any computer could ever be."
"Dave Sharples had a pretty lofty idea. He wanted to create an entirely new instrument. Not just another keyboard based synthesizer or grid of buttons. He wanted to make an interface that felt entirely different. He pulled it off pretty well with the Joytone."
"It’s truly an astounding project that is a thing of beauty."
