This iPad app called Artikulator is not yet released but this clip is really interesting. The app lets you create music visually . Just slide your fingers on the touch-screen and shape the sound you want. Curve a line upwards and it will create a higher pitch. If you make a line big the sound will be louder.

Developers Mike Rotondo and Luke Iannini constructed the app in about 24 hours during a Music Hackday, a series of events that combines art and technology with fascinating results. They hope to release their creation in the App Store soon, and they won’t be charging for the initial version. We also saw the app running on an iPhone, for those of you who don’t have iPads.And yes, they’re aware this demo sounds like “dying cats”; more timbres and sounds will be available.We think this interface is a wonderful way to teach and learn about music and to express creative urges without getting mired down in the technicalities of making and producing music. What’s your take on it: Could you see yourself playing with an “instrument” such as this one?

Description from Korg:

With the iELECTRIBE, sound creation is easy, fun and intuitive – just as on a vintage analog synthesizer. Simply choose a part (or sound) and touch the 16-step sequencer to quickly build a groove. This easy-to-use interface combines forces with the iPad’s 9.7” multi touch display to offer an intuitive “hardware” feel, sure to inspire and captivate the imagination of any user.

The iELECTRIBE faithfully recreates the historic ELECTRIBE·R’s entire sound engine and sequencer capabilities. In addition, it provides advanced Motion Sequencing, eight supercharged effect types, plus 64 new preset patterns that instantly allow the user to create music in a wide variety of dance and electronic music styles.

This is a pre release screenshot of the White Noise Audio "bleep!BOX". It's been two weeks since Steve Jobs unveiled the iPad. I've always said it will be really interesting to see what musical apps will be like for it. Now we can see the first ones coming up. It's remakes of apps made for the iPhone. Its a start and it will get better in time.

This is what White Noise Audio says about their new app:

"The bigger interface will allow for a better 'heads up' display of the full tune you are working on, as well as global access to things like the mute buttons," says developer David Wallin. "Navigation will also be a lot easier. After the first release, I will work on adding some additional features (aside from just enhanced UIs)."
