KLANG began as we wanted to coordinate all our old MIDI synths, drum machines, modular systems, and software into a single evolving instrument, machine, system that we could perform with... like a control room from an imaginary science-fiction film.

So we went into our studio and started experimenting, prototyping and building systems. Over time, KLANG emerged from those experiments as a way to coordinate machines, behaviours and performance across an evolving hybrid studio.

KLANG is a visual, component-based music software environment for building and performing custom, hybrid music systems across modular, retro MIDI and semi-modular systems.

IT IS FOR SOUND - PERFORMANCE, EXPLORATION and EXPERIMENTATION.

It integrates and coordinates Eurorack, MIDI, and digital processes into a single real-time system, creating controller-based hyper instruments or systems that can be let loose,  steered and influenced.

KLANG emerges from our long-running experimental systems practice spanning computer science, computational media art, behavioural software and hybrid electronic music systems, 

KLANG is designed as a bridge between software and physical instruments. It provides seamless CV/Gate and MIDI connectivity, enabling bidirectional communication between patches and hardware and Midi Controllers. Users can map virtual modules directly to physical control voltages, automate modular rigs, or use hardware signals to drive software behavior.

The environment functions as both a standalone system and a central hub within a studio or live setup. It supports building custom sequencers, modulation networks, audio tools, and hybrid instruments that span analogue and digital domains. With a focus on immediacy and performance, 

In essence, KLANG transforms a collection of instruments into a unified, programmable sonic ecosystem—where patch cables and virtual connections coexist, and where composition, synthesis, and performance become a single, continuous process.

LIKE THE UNIVERSE - KLANG IS   EXPANDING - 

whilst maintaining a coherent how-it-works with integrating new ideas of how to build and transform the behaviour of component-based systems software for performance, exploration and experimentation,

KLANG augments Eurorack modular systems through MIDI-to-CV integration, using its own open-ended system and process construction to generate evolving control structures, behaviours, and interactions beyond conventional patching.

In the early 2000s, Robot Software was immersed in the glitch-era experimental MIDI and digital sound culture, error, the aesthetic of failure and unconventional MIDI use.

We researched and practised “extended MIDI techniques” - performing with our custom systems and software at festivals such as Sónar Barcelona. We are bringing this experience to Klang.

Techniques that enable the experimental reuse of OBSOLETE MIDI synthesisers, or modern synths, revealing sounds and behaviours never intended by the original machines.

El Pais interview 2002

'".... uses a somewhat outdated Yamaha sound module, but it uses computers to take it to the brink of binary collapse with an overwhelming flow of information. 'The result is totally novel sounds that would not normally come out of that instrument'

As software, as art, as utility.

For example, a Korg Volca Drum becomes a behavioural rhythm system in which continuous CC bombardment produces evolving percussion, shifting resonance and dynamic rhythmic instability, or can be pushed to reveal hidden behaviours of drones, waveform chaos, or toward dense digital texture that goes beyond its role as a compact drum machine.

Animate everything. With  modulators, you can go far beyond its traditional usage and explore unique  volca-drum FX and timbres.
