Lydia Kavina: Theremin repertoire (by tvox)

The theremin repertoire is quite large. In earlier times, there was a belief that the theremin was only suitable for lyrical, slow melodies or spooky, sci-fi, and psychedelic effects. However, this myth was refuted long ago. The pieces you can play are those you can work out musically. It depends on your musical taste and experience.

The theremin is used in classical, contemporary, jazz, and popular music, as well as in different kinds of experimental art.

See below the link to most popular works played on the theremin, with the links to the recordings.

International Theremin Camp in Copenhagen (by tvox)

International Theremin Camp in Copenhagen is a Theremin-themed holiday, all about fun! It happened in 2024 for the fist time.

This year it will be on 22-26 June 2026. It brings together theremin enthusiasts for workshops, ensembles, performances, and community building. There is also a rare opportunity to get lessons from four teachers: Lydia Kavina, Thorwald Jørgensen, Carolina Eyck and Veronik

Lydia Kavina: recommendations for theremin composing (by ILYA)

It’s about nothing. ‘Water is wet, and the sound of a violin is triangular.’

It would be more interesting to hear, for example, about such subtleties: which passage is easier to perform — a linear one, like C-D-E-F-G, or a leaping one, like C-F-D-G-E?

Moog Theremini firmware update now available (by dewster)

The Theremini Windows editor is back on-line (IIRC it disappeared for a long time): https://www.moogmusic.com/downloads/

At the very least, the selling off of Moog Music to the octopus conglomerate got rid of their idiotic sideways scrolling web site. That right there may have hastened their demise a bit.

Moog Theremini firmware update now available (by Urban Rambler)

Hello,

Coming very late to this - is there a copy of the latest firmware update for the Theremini available anywhere? It is no longer on the mood site. Thanks all!

Domo Arigato Mr. Roboto

Carolina was involved in a robotics demo project, which ended up employing the D-Lev:

They do make beautiful music together!

I guess it's kinda fitting that the robot is playing a digital Theremin!

DIY Calculator (by oskaps)

Nice idea 👍
A console-based RPN calculator sounds really powerful, especially for speed-focused users who prefer keyboard input over GUI tools. Keeping it simple and avoiding unnecessary features like logic or statistics actually makes it more efficient and closer to classic HP calculators.
For example, an Online Grade Converter can be thought of as a system that takes different academic inputs, processes them step by step, and produces a final calculated result in a very structured way. Similarly, a Destiny Matrix Compatibility Analysis works by interpreting input values and converting them into meaningful compatibility outcomes based on defined rules.
Your idea follows the same core principle of structured input → processing → output, just in a more advanced technical and programmable direction.

Etherwave Standard: Searching for Solution to Demolished L6 Coil (Horror Story?) (by HowieZowie)

Does anyone know where I can get a schematic for the new/2022 Etherwave for my repair guy? He has modified my Big Briar to be guitar versus line level output, and needs a schematic to work out the same mod for my new one so they are interchangeable in my rig. Any help or guidance is appreciated!

Moog (New) Etherwave discontiued? (by HowieZowie)

New Moog Etherwave Theremin (by HowieZowie)

New Moog Etherwave Theremin A new version with a new design, including the CV control and headphone jack of the EW Plus, and several new conveniences: a mute button (also with a foot switch jack), quick-release antennas and detachable mic stand attachment. A standard power connector (not that weird DIN thing) and HOORAY!, what appears to be an easy access to calibrate the instrument, instead of having to disassemble it almost entirely.They also mention "improved bass response"...could it be they finally incorporated the ESPE01 mods?

"Will original D-Lev kit contents fit into this box?" - Buggins

Yes, the original kit is inside there.

"Could you please share more details about antennas construction? It looks impressive, and better than plumbing (etherwave-like) solution."

The PDF write-up linked above has some details, including the connectors (your list is correct). I didn't take any pictures of the process other than those in the write-up. Either 3/8" milky white poly tubing or 3/8" gray PEX tubing (the short sections with the knob on the end that connect to faucets) should work.

I'm thinking of removing the ground banana jack and substituting a TOSLINK keystone. Powering the DAC internally introduces hum problems in some setups, which an external DAC fixes.

Eric, really nice build. I want to do similar one.

Are the RF connectors the following ones?
* SO-239 female x2
* PL-259 male plug
* PL-259 adapter / elbow

Tour 2

I just finished another build, this one was unfortunately gestating for years due to my laziness and life in general. I think it turned out pretty nice:

Did a write-up on it here: https://d-lev.com/support/D-Lev_Tour2_Kit_Build_2026-05-23.pdf

Love that Dura Tex finish!

Early electronic music before 1945 Substack site with extensive theremin history (by JPascal)

Thank you very much! The significance of those months, when Termen came to Germany and other European countries, is absolutely underestimated. Others (myself included) have also explored this topic, and I am sure there will be further articles on this period of collaboration in Germany in the future.

Early electronic music before 1945 Substack site with extensive theremin history (by DreadVox)

Just happened on this substack site, started in September last year, with articles about pre-1945 electronic music including about the first demonstrations of the theremin outside Russia, with posters, photos and press articles, and about the wherebouts of the Theremin Trio that operated out of the Berlin School for Electrical Music.

The End Is Near? (by André)

I just received an email from Thereminworld Patreon site.

It says that I am a free subscriber and proposes to upgrade to a paid membership.

I guess this is an automatic email. It's in french.

Jason, are you still with us?

Full Metal Hot End (Let The Filament Flow)

I like my Ender 3, but of course it has been somewhat necessarily modified (notably a new controller board & magnetic textured print bed which should have been standard equipment IMO). Previously the filament feed motor was moved from the chassis to the X axis, making it more of a direct feed than a Teflon Bowden tube type. While this was in many ways an improvement due to reduced retraction and stringing, the remaining short length of Teflon tubing still went all the way to the print nozzle, and over time the tube would degrade with heat, necessitating replacement. It's kinda tricky to know when the tube is at fault, so you end up replacing any time prints start looking bedraggled. One can purchase full metal hot ends, but I was unaware until shopping on-line that one could also just replace the feeder tube with an all metal version at a much lower cost. I got this on Amazon for $12 USD and some change (https://www.amazon.com/dp/B0971FNCM4):

I installed it and did a print. Afterward I noticed that there was a lot of leakage at the top of the aluminum heat block, and the nozzle was at a funny angle. Turns out the block threads on the nozzle side were stripped, which is something that just happens when you have to periodically replace the Teflon tube. Looking around on Amazon, I found this brass version for $9 USD, which comes with a new rubber boot (https://www.amazon.com/dp/B0CLD54CYF):

I very carefully moved the thermocouple and heater element over to the new block, using Creality thermal grease for both. I also put some grease on the metal feeder tube. Afterward I heated it up to operating temperature (240C) and re-tightened everything. The PID adjustment was built-in to the software, so that was pretty quick and painless.

So, one more mod, and hopefully I'll never have to mess with the stupid Teflon tube again. Since the filament has much more contact with the hot end it may be able to print better with larger nozzles and higher flow rates (it's all about the flow).

Open Theremin V4 with MIDI (by dewster)

Surge XT is a pretty nice synth and works great in Linux - thanks for turning me on to that too!
