Light Theremin 5.2

A new Innovative way to create music, the Light Theremin takes readings from the device's light sensor and uses it to modulate the frequency of an oscillator - more light equals higher frequency.

This is, as far as I know, the first and only Light Theremin instrument on Google play. Which I am proud of :)


HOW TO PLAY THE THERELUMINOUS

♬ The app uses the device's light sensor (not proximity sensor), so consider the location of the device's light sensor when using it.

♬ Highly lit environment may be best for the light theremin, as it allows the most sensitivity. In a dim environment you can calibrate the light to a higher frequency using the calibration buttons.

♬ Consider working with a flashlight or a lamp, directing it closer and further from the light sensor, or covering/revealing the sensor with your hand.
Working with a dimmer and fading the light in and out is a great option.

♬ Nice settings to try:
- Sin and Saw waves sounds best in my opinion.
- Blues and Hijaz scales has the most interesting color, with Pentatonic you can never go wrong.
- Changing the Reverb produces interesting results, try going through the whole scale.
- 25% - 75% Glissando for the ideal Theremin-like sound.
- Try experimenting with different tempos. You can play a drum loop with the same tempo as the Light Theremin and synchronize the two.

♬ Don't use near dogs in a highly lit environment. Be nice.

♬ Requires practice for good results, just like a real Theremin does!

THE LIGHT THEREMIN CHALLENGE

Think you've mastered the art of the Light Theremin?
I would love to get a video of you playing it so I could feature it, with proper credit of course, on iLyich games' social media networks, and maybe even as the demonstration video for this app!

FEATURES

♬ You can play exact frequencies of tones in six different scales - Chromatic, Major, Minor, Blues, Pentatonic, and Makam Hijaz.

♬ Choose one of four different wave forms - Sine, Triangle, Square, Saw.

♬ Calibrate the theremin's frequency to the light ambience around you - The light reading is translated to 440, 880, or 1,320 Hz.

♬ Adjust the glissando - 1, 18, 65, 120, 450 ms. (also has an affect on the sensitivity of the readings - more glissando means lower sensitivity so it can reach the note before the next reading occurs).

♬ Adjust the tempo of the readings - 60, 120, 180, 240 bpm (e.g. 120bpm will send a reading every 500ms).

♬ Device won't go to sleep while the app is on, which is ideal for live performance.

♬ Mute button, Reset button.

♬ There is a (very basic) built-in game, featuring a light-controlled spaceship!

♬ This is a full-featured version with no in-app purchases, no freemium, and no intrusive ads (only a small banner ad at the bottom of the screen).


LIBRARY CREDITS

To make it all happen, the Light Theremin uses the following libraries:

★ T "timbre.js" (Synthesis)
★ Insomnia-PhoneGap-Plugin (Keeping the device awake)
★ cordova-plugin-lightsensor (Getting light sensor readings)
★ Teoria.js (Easily converting tones to frequencies)
★ Phaser.js (UI)
