Flexur and Chill, with this Trautonium-inspired DIY synthesizer

I missed this when it dropped earlier this month — Synthtopia was there! But now is a perfect time to chill out to the smoothly gliding sounds of this original Trautonium-inspired synthesizer design in progress. Flexur can cool down an overheated Europe.

Casio’s expressive guitar strap controller was inspired by a chopstick case

Surprise! Casio has something unexpected — Dimension Shifter, a spring-powered expressive wireless controller that attaches to your guitar strap. And it was the invention of one employee, inspired by his kid’s school-lunch retracting chopstick and cutlery case.

GForce just made a West Coast, MPE-playable synth playground

GForce’s MAP is all new — it’s not a recreation or a collaboration with other brands. But this synth has been to history class, studying modular designs by Serge Tcherepnin, Random*Source, and Buchla USA. Put that in a very modern interface, add MPE expression, and you get what feels like Massive X or Serum from an alternate universe where they’re all about West Coast synthesis.
