iThereal for iOS is a multi-function Inter-App Audio App, virtual Theremin and MIDI controller, and an expanded Theremin instrument that allows for more modern Theremin gestures.
In many senses it is a classic Theremin but it has the freedom to incorporate newer techniques for playing and interfacing that were unavailable in its predecessor.
With iThereal iOS, the original Theremin's interface of proximity to the instrument's antennae has been replaced with a sophisticated use of touch gesturing and the ability to use an iOS device's internal Gyroscope to influence pitch and volume.
Using iThereal as a MIDI controller allows the performer to incorporate gesturing and Gyroscope functions to control almost any voice available through Inter-App Audio Hosts (such as GarageBand). Connect your iOS device through Wi-Fi or MIDI cable to send raw MIDI data using iThereal to a device that reads MIDI.
-Turn on 'Vibrato' in real time to color your sound without disturbing your musical decisions, choosing both depth and rate of modulation.
-A new feature we call 'Discrete Portamento' gives the effect of a real-time sequencer whose sequence is modified by the choice of your notes.
-Using GarageBand your instrument can be modified to include effects such as Reverb, Echo, etc.
-A thoroughly customizable User Interface.
iThereal iOS frees the musician to explore a sonic tapestry of unlimited possibilities.
