This is a multitouch synth instrument. Play it by touching and swiping the screen, changing the waveforms and sliding the effects to create anything from traditional sci-fi theremin sounds to deep scuzzy soundscapes. Use the looper controls to record, loop and overdub layers. Then if you wish to save or share your recording, hit the download button to send your wav file to other compatible apps like Messages, Email, Dropbox etc. The original Theremin went live in 2014 on the web at femurdesign.com/theremin. Over a million hits later and hundreds of requests for a record button, I have redesigned it. Now the Theremin is ready for you to experiment with. Happy playing! -- SPECIFICATIONS -- • Record, loop and overdub options. • Multitouch allows up to 8 tones to be played simultaneously with your fingers • 3 sliders: delay, feedback and scuzz • 4 waveforms: sine, square, triangle and saw • No internet needed, works both online and offline • Download the loop as a .wav file • Loops can be shared with other apps like Mail, Message and more. • 1000+ installs • Compatible with iOS versions 8 - 10 • Optimized for iPhone, iPad & iPad Pro -- REVIEWS -- Gizmodo "Just mess around! Twiddle those faders! Swipe and click with reckless abandon! Turn the volume all the way up, give the dog a panic fit, and make your neighbours think the street's being invaded by giant cabbage people from planet Zok. Trust me, this will never get old.” Dangerous Minds “New online theremin simulator kind of sounds cooler than the real thing.

neo Drone is innovative theremin like synthesizer. The pitch of the oscillators is controlled by moving your hand in the air without touching the device. The hand is tracked by the front face camera. Description video to see it in action: https://www.youtube.com/watch?v=1qACS_XJ_cg The algorithm behind was made by me on the second Music Hakathon in Sofia. You can control the range of the synth by adjusting the light sensitivity, but the app is not working in dark environments. The tonal range is 2 and a half octaves and you can play in legato and staccato mode. The touch area of the device is working as a kill switch so you can produce these talking synth sound. Features: - play without touching the device - kill switch - 2.5 octaves - adjust camera range with light sensitivity slider - core midi - so you can add USB midi keyboard to the show - nice and fat sound - visual color indicator for the playing note - legato and staccato mode
