The app displays user interface objects on the iPhone similar to those found in Max, the objects are created by sending messages like ‘slider volume 100 100′ to the c74 external (which is available for free at http://www.nr74.org/c74/c74v1.3.zip). The external also works within Max4Live enabling control of Ableton Live as well.
Next to the user interface aspects of the app, c74 is also able to forward :
- accelerometer data
- shake gestures
- proximity sensor
