Since the original Theramin heterodyned the oscillator controlled by the hand I believe you could set it to go either way too by choosing high or low local oscillator frequency. Or even to reduce in frequency on approach down to zero and start...
I will certainly add a switch to choose the orientation of the pitch.
I have tested it quite a lot now, and it is really fun to play. There is of course room for improvements ! I have used a VL53L1X sensor to mesure distance. I appears to be a...
This is to announce a new instrumentation board for Teensy 4.x (and other Arduino type boards with SPI interfaces).
This is an instrumentation amplifier input board that can provide high bandwidth measurements for a high impedance source. The...
Love the "scale mode". Great work!
I restored a 1961 Moog Melodia Theremin for a friend. Quite the challenge to adjust all the tuning coils. Emulating with a Teensy opens up new territory to explore.
BTW, most Theremin's increase the note...
I received my Teensy Audio Adaptor Saturday... I experimented with it today.
I added the I2C SGTL5000 control to enable it and to set Volume to 1 (version alpha002).
This Audio Adaptor sounds really great at 96kHz !
Hi, This keyboard is a mini piano instrument with Teensy 4.1, 24 buttons, 4 potentiometers and a lot of additional adjustment power, as well as a Midi keyboard and speaker output with built-in SGTL5000 (via SD CARD). Each button has the ability...
This project turned out to be simpler and more fun than I thought. In a nutshell it is just an infrared frame (to get touch from a monitor) mounted on a piece of wood and connected via USB-Host to a Teensy 4. The Teensy 4 has some WS2812 LEDs and...
The project "Thierry-Rochebois-I" has been updated to alpha001
with 8 more presets and all "morphemes" implemented.

Hey All! Using the Teensy Audio Library and Teensy 4.0, I built a 3-layer polyphonic synthesizer. The...
Great projects. Will you come to the Synfest France? It's a very friendly event where DiY enthusiasts like you and me are welcome. It is located near Nantes and is scheduled in april.
As this part of the forum isn't that busy, I'll post an update. Inspired by PositionHigh and other legends I made a remote UI application using webSerial. This was actually very easy since I already have a "display module" that communicates with...
Time to satisfy your retro cravings! I revisited this old project recently and did some well needed updates. It is a polysynth based on (real) commodore SID's. It accepts up to four of them and supports both 8580 and 6581 variants. Control is...
Hi there,
Here is my latest project that I wanted to share : the minichord!
For the full documentation of this fully open source project, first the Github (https://github.com/BenjaminPoilve/minichord/tree/main), then the website...
Hello,
Here is another Theremin ! This one is very simple : a Time of Flight sensor for the pitch, and FSR for volume. The synth section is also very simple, just one oscillator, a LP filter, minimalist LFO and reverb. In fact, this project is...
I did not tried it yet with the pjrc audio adaptor.
I’ve just ordered one from a retailer.
I will test it as soon as i get it.
Thanks to everyone that helped me to understand how powerful the Teensy4.1 can be.
Transdimensional is a fancy name for a way to simplify the use of very complicated synthesis algorithm.
It is a kind of morphing that takes care of navigating through the synthesis parameter hyperspace.
This first synth navigates in a 54...
