## What is Theremin Synth?

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!

-- 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. Check it out and annoy your co-workers.”

Mashable “Messing around with this virtual theremin is completely addicting”

### 1/5 — I want my money back

*2019-03-27*

The app only works with earphones, I can’t record and save the sounds I’m making.
Give my money back!

### 5/5 — Working on iPhone 7?

*2016-12-02*

This is probably my favorite app. But I can't get it to work on iPhone 7. Had the same problem on 5s.

### 4/5 — Very fun

*2016-10-14*

Could benefit from some more robust/granular settings and the ability to record and download a session (instead of just a sample loop), but in general this is pretty bangin. Good dynamic range (you can really lay down a bass line on this with some practice and a good amp/pair of headphones), some nice tones, really intuitive and fluid for constructing loops, adding to them, and breaking them down on the fly. Considering incorporating it into performance.

### 2/5 — Absolute meh

*2016-09-23*

The y-axis filter effect is pretty weak. But since there is zero customization available beyond picking a waveform there is no way to vary the sound very much. And unlike an actual theremin there's no way to vary the volume(!). It's simply annoying full volume or off. Oy.

No way is this worth $3, barely worth $1. Feh.

### 5/5 — Amazing

*2016-05-30, version 2.0.4*

Amazing-just buy

### 5/5 — No sound issue on iPhone solved

*2016-05-26*

If you don't get audio on iPhone make sure the ringer switch is in the on position.

This app is addictive!😀

### 1/5 — Help. No sound.

*2016-05-16*

I loaded this app at suggestion of WFMU tweet. Looks cool but no sound. Using iphone 6 with latest ios. And yes volume is up. Tried powering down. Out of ideas. Help please.

### 2/5 — Needs work to make it a half decent app

*2016-05-07, version 2.0.3*

My major gripe with this"instrument" is that you cannot fade the notes in.  With a tiny amount of thought this would be easy to implement by just separating the play and effect areas.

Secondly the iPad screen does not have enough precision to accurately tap a reliable note, Multiple scales with tuneable accuracy would fix that.

Finally take a look at Bebot or Animoog if you want great playability.  This app has got a long way to go before it becomes musical.

### 5/5 — Woah

*2016-05-07*

This app is amazing! The amount of available waveforms and filters allows for a ridiculous number of sounds one can achieve. Multi touch integration is perfect and multiple notes can be played while adjusting filters on the fly. The record and export feature is awesome as well!! In some ways this reminds me of KORG mini synths from a few years back.

### 5/5 — So sick.

*2016-05-06, version 2.0.3*

I have spent hours playing on this now. Very easy to pick up and make some sound.. After a while it even starts to sound good. Starting to wonder if I can use this in a live setting as a full on instrument.
