Ethero 2 Live Demo
Ethero is the iPhone’s answer to the etherophone, or Theremin as it’s better known. The Theremin is one of the earliest electronic instruments ever created and it’s now famous for it’s signature eerie sound.
The traditional Theremin is usually controlled without any physical contact, with the player using each hand to control both the pitch and the volume of the sound. Ethero works in a slightly different way, but it still attempts to emulate the real instrument! Ethero takes the amount of light coming into the device’s camera and translates it into a sound frequency. So, waving your hand or another object in front of the device camera will change the pitch of the sound. The more light coming into the camera, the higher the pitch. To control the volume of the sound, simply touch the screen of the iphone and move it up and down the screen.
“This is just a quick demo of Ethero 2 running live on my iPad 2.
The video shows a couple of the preset scales in the app. The synth sounds are from the Moog Animoog which is running in background-audio mode and being controlled via virtual MIDI ports.
Ethero 2 will run on iPhone 3GS, iPhone 4, iPhone 4S and iPad 2.
MIDI is sent over virtual ports, WIFI and via the Camera Connection Kit. Of course, your mileage will vary with the use of virtual MIDI ports as there’s quite a lot of processing going on. It works best on the iPhone 4S and iPad 2 (and I guess ‘the new iPad’, but I can’t test that… yet!) “
