Ethero 2 app for iPhone and iPad

-------- NOTE --------
This application transmits MIDI notes via the Camera Connection Kit, Virtual MIDI ports and MIDI over Wifi. It does not make any sound itself
----------------------

Ethero 2 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 2 works in a slightly different way, and rather than generating sound, will generate a MIDI note!

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 sent.

You can the MIDI output of Ethero 2 using either the Camera Connection Kit (the USB plug) or MIDI over Wifi.

MIDI is also transmit over virtual ports so you can have Ethero 2 control any MIDI-enabled application on the same device.

Features:
- Choose front or back camera (if you have an iPhone 4 or iPod Touch 4G, or higher)
- Pick the octave. The lowest note (i.e. when theres no light coming into the camera) will be start of the octave.
- Pick your own scale. There are presets for Major, Minor, Major Pentatonic and Minor Pentatonic scales, but you can pick any notes you like!
- Pick the key. As well as choosing the actual notes of the scale, choose the key.
- Calibration. Set up your device in its normal un-used state and calibrate which sets the ambient level of light to the lowest note the app will play.

More to come in the next update:
- Choose the range of octaves you can play over
- Choose to send MIDI CC messages rather than being limited to pitch
- Lots more...!
