Put on your headset, flip the switch, and play. A real instrument floats before you — responsive, expressive, and endlessly tunable.

✨ New in Version 1.1

  • Hand tracking greatly improved, closer to a real theremin where subtle finger movements matter.
  • New reverb acoustically modeled from a cathedral

👻 Ghost Hands Add-On

Record your hand movements and perform alongside your past self. Layer phrases, build harmonies, or turn your room into a haunted chamber orchestra.

🎛️ Shape Your Sound

Adjust knobs: point your controller, pull the trigger, then turn — or pull outward and orbit for more precision.

  • Amplitude Curve – shape how your left hand controls volume
  • Timbre – from pure sine wave to rich violin tones
  • Reverb – simulated room acoustics surround you with sound
  • Number of Octaves – define your instrument’s range
  • Lowest frequency – from deep bass to sparkling highs

🎻 Designed for Expression

  • Linear pitch spacing – equal distance between notes
  • Pitch hologram – a luminous ruler showing where notes live
  • Adjustable reach – move the low note closer or farther away
  • Touch Controller precision – stable optical tracking, no “magic electromagnetic circle” required 💫

A great minimalist instrument for Quest.

I'm a different developer who also made a theremin app (Nocturne), so I can appreciate the decisions that were made. - Simplicity. Much like a real theremin there's not a lot of options but they're carefully selected. This makes the app easy to approach. I went the opposite route with mine. - Ease of use - going from regular theremin I was able to play music immediately. The pitch guides help keep you on track. - Very low latency - the developer streamlined the audio to make sure there's no discernable delay between your motion and the sound. Probably the single most critical thing in a VR theremin app. - Smoothness of pitch signal - pitch changes smoothly rather than at the screen refresh rate. Easy to get wrong. - Synthesis - very faithful to real theremins, like moog. No pops or discontinuities in the waveform. Overall a great minimalist theremin app which nails the audio and interface fundamentals.

Great instrument app!

This theremin app is really fun. Never played the real instrument but this seems very realistic. You can move the speaker position, adjust different settings on the instrument... The big plus for me is the "scale viewer", you can rely a bit on your eyes and not solely on your ears. It sounds very realistic! Recommended! Give it a try

Just great!

Such a great execution with no clutter. You immediately get how it works and it sounds great. You can easily spend hours at a time playing this.

Wonderful! My new go-to VR experience!

Genuinely brilliant. I've always wanted to try a real Theremin, but sadly I can't afford one. A few days ago I wondered to myself if there might be a VR version of one out there, and then found out this had just been released 3 days earlier; what great, serendipitous timing! This fab VR instrument is very obvious and intuitive to use from the outset. When you fire up the app, it appears in front of you, in mixed reality, with the rest of your room around you, ready to go. With the flick of the virtual power switch on the instrument, it's on and you're playing! Your left hand controls the volume, your right hand controls the pitch. There's a scale for both, to help guide you. You can grab the virtual Theremin and put it down where you'd like it in your mixed reality environment; you can move the virtual speaker similarly. Through control knobs along the front of the virtual instrument, you can alter the volume response, the timbre, reverb, number of octaves, and lowest frequency. There's no lag/delay, it's very responsive indeed. I find it deeply relaxing and enjoyable playing along with other music, it's really quite therapeutic. Just like, I imagine, the real thing would, it does take a little time to get used to playing it, but it's worth it. I agree with one of the other reviewer's suggestions, that maybe the development might consider adding the notes to the pitch scale? Additionally, I'd like to see the ability to save and recall the instrument's settings? But even exactly as it is, I'm delighted with it. Now, the only problem is, it's so good that it makes me want a real Theremin all the more (in case something happens to my Quest 2!) 🤣

I always wanted to try a theremin!

It seems like the perfect instrument for VR when you think about it. Very user friendly. I picked up on how it worked almost instantly and was making fun interesting melodies in no time. The floating virtual note markers made it easy to stay in tune as well. Overall I'm happy with this and I'm looking forward to experimenting with it more.
