Theremin (Motion Sensors and Touch Screen)

This app has been updated by Apple to display the Apple Watch app icon. Updated the font for a modern look.

Added a store section. Available purchased include: * Scales/Keys for Auto-Tuning - Chromatic, A Major, C Minor, etc... * Camera Sensor - Using the center pixel of a live camera feed, each pixel color drives a synthesizer channel (RGB). * Graph Output - Monitor the motion sensor output with a live graph. Added a more accurate slider control for in several settings. Updated informative labels.

Reworked the user interface for configuring the synthesizers and other settings. Updates to the synthesizer code as well. Added a quick connect for AirPlay.

Since an iOS device cannot sense capacitance, the motion sensors and touch screen are used to alter the audio output. You can assign audio channels to the axes of 4 inputs: 1.) Touchscreen (x,y) 2.) Accelerometers (x,y,z) 3.) Gyrosocopes (x,y,z) 4.) Magnetometers (x,y,z) That's 11 channels total (each axis gets one). A channel has 1.) Min, max, and current frequencies 2.) A waveform (sin, square, triangle, sawtoot) 3.) An effect (such as snapping to closest half note). 4.) A sensitivity rating (how sensitive is it going to be when you apply force to an accelerometer, or torque to a gyro, etc...) 5.) Amplitude. To mute a channel, set its amplitude to zero.

Use either the front or the back camera as a sensor source to drive 3 synthesizers. Red, Green, and Blue values of the center pixel each drive their own synthesizer, similar to XYZ for any of the motion sensors.

This purchase allows you to assign a scale to the Autotune Effect. It includes all major and minor scales. When autotune is turned on, it will snap to the nearest note, sort of like frets on a guitar. The chromatic scale is free and built into the app.

Data from the sensors will be plotted in real time which replaces the free text based interface. It also graphs the recent max/min values, which you can reset at any time.
