Elektrofon Klang Eurorack 4-Channel Chord Sequencer Module

We say...

It's back! This beautifully designed chord sequencer has been long unavailable but is now back in production. If you're looking for a way to add polyphonic chord progressions to your Eurorack setup, look no further.

Manufacturer's description

KLANG is a four voice polyphonic controller. It stores, traverses and manipulates chord progressions.

Although it was designed as a tool for making polyphony more accessible in Eurorack, it can be used for many other purposes. Think of it as a four channel sequencer and use it to inject precision voltages wherever you need them.

KLANG is inherently musical. It speaks tonal cents and defaults to the twelve note chromatic scale.
If you wish you can go between semitones and play with microtonality or dial in those specific sweet spots on your favourite filter.

All of KLANGs functionality is available without any form of menu diving. Everything is front and centre and every function has dedicated inputs or controls.

A note on the new version

The first version of KLANG was introduced on the market in 2019. It was on sale until the pandemic created unrecoverable supply chain issues – Resulting in no units being produced between 2020 and 2024.

KLANG had to be redesigned from the ground up with all new components and with careful attention to not get into this position again. It took a while to get the funding needed for a redesign, and it also took a very long time to find the right manufacturing partners.

The upside to all this is that the new version of KLANG is an improvement on all levels. Front and center is a larger display with twice the resolution, all new injection molded parts that are much closer to the original vision, and the addition of a reset input that makes KLANG a fully fledged four channel sequencer.

Inside, KLANG has a better chipset that outperforms the previous design even though it uses less power.
