Elektrofon - Klang (2025)

The idea behind Elektrofon's Klang is so simple and effective, it makes you wonder why it hasn't been done this way before. Instead of patching together multiple quantizers and precision adders to build chords, Klang gives you a single, clear interface. At its center is a nice-looking clock-like OLED display with four dials, one for each voice. You turn the corresponding encoder, and the note moves. That’s it. You can immediately see the relationships between notes, making the construction of harmonies and voice leading an intuitive and visual process.

It’s this directness that makes Klang feel less like a utility module and more like an instrument in its own right. Most of its functionality is easy enough to understand without having to plow through the manual in advance. You can store entire progressions and then step through them with external triggers, essentially turning it into a powerful four-voice sequencer. While the core operation is immediate, there’s plenty of depth for those who want it. CV inputs for transposition and direction allow for complex, evolving sequences, and a long press on any encoder unlocks microtonal adjustments for exploring scales beyond the standard 12-tone system.

Many will remember the original Klang, which disappeared for a few years due to the global parts shortage. This new version isn't just a simple component swap; it's a ground-up redesign that improves on the original in every way. The screen is larger and brighter, the build is more robust, and the core is more powerful and efficient. It gets out of your way by removing menu-diving entirely, letting you focus on the musical ideas you want to express. For anyone looking to bring polyphony into their rack without the headache, Klang just makes sense.
