App Description

Turning your iPad in to a classic sounding theremin.

The E-Theremin MkII translates the unique and distinctly eerie sound of the theremin onto a digital interface, allowing you to control pitch and volume on a x/y pad. A second x/y pad is provided for controlling vibrato. Additional controls are accessible for control of the waveform, band pass filter, and envelopes. Two DSP effects; reverb and delay let you take your sound to a whole new level. The reverb's room size can be set to small room all the way up to unearthly vast spaces.

1.2 introduces a 4 octave keyboards and two part polyphony (one part for X/Y pad, one part for keyboard).
