## What is E?

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).

### 1/5 — Should have 5 star, gave it a 1

*2017-12-12, version 1.2*

Lots of fun and far easier to use than a theremin. Only one minor problem no obvious way to record or save. Ah you say Garage Band, sorry, the icon is there but when you try to access it it says not available at this time. Give us a record/save and/or make it work with inter audio and you get a 5. No excuse having to analog record electronic instruments with external recorder!

### 3/5 — Novelty, not very pro.

*2017-02-01, version 1.2*

Fun theremin effect and tone.  Cannot glide over keys must press each note.  Limited range adjustment in freestyle glide window.  Free versions are adequate at this point imo.

### 5/5 — Theremin

*2016-03-11, version 1.2*

After seeing a recent Google animation on the Theremin I decided to find an app for that. This one will not disappoint. Hours of fun.

### 4/5 — Expressive Instrument

*2014-11-21, version 1.1*

It’s not my most used tool but I like how expressive it is and is good to revisit every now and then. Definitely recommended and goes well with a little history research of the Theremin and learning the instrument that really started it all.

### 4/5 — Really Nice iOS Theremin

*2014-10-16, version 1.1*

This app has a good sound, classic design, and the controls are simple to use. Really worth the money
