Reaktor 6 is a modular sound studio and instrument builder from Native Instruments. It combines a large factory library, a community user library, and deep patching tools for creating synths, effects, and experimental sound tools.

Creative Sound Playground
Reaktor 6 is a modular environment designed for deep sound exploration and custom instrument creation. It provides a sandbox for building anything from simple synths to complex effects, with a focus on unique, experimental results. The platform runs standalone or as a plugin within a digital audio workstation, offering flexible integration into any setup.
The included Factory Library features over 70 ready-to-use instruments and effects, covering synthesizers, groove boxes, and sound design tools. This collection provides immediate inspiration for music production. A separate User Library contains over 4,000 community-created devices, including drum machines, delays, and emulations of classic hardware.
Modular Patching and Blocks
Reaktor’s Rack mode introduces Blocks, a simplified patching system with color-coded cables on the front panel. You can connect modules to modulate parameters in intuitive ways, allowing for surprising and creative sound outcomes. The modules are designed to behave predictably even with feedback routing, which is notable for a software system.
The classic Ensemble mode offers deeper patching. You can add a sequencer to a synth, chain effects, or route internal MIDI between devices. This level allows combining existing instruments with new sound sources to create entirely new configurations, bridging the gap between simple patching and full instrument building.
Building Custom Instruments
Reaktor provides two structural levels for building devices: Primary and Core. Primary handles parameters, events, MIDI, and OSC data using a graphical signal-flow paradigm. Core features a runtime machine-code audio compiler for custom DSP algorithms, ideal for advanced sound processing and low-level control.
A comprehensive library of Primary and Core macros provides raw materials to design simple synthesizers, live performance tools, or granular processors. Builders can use these components as starting points for creating custom systems from the ground up, then share their creations with the community via the User Library.
Workflows and Applications
For music producers, Reaktor serves as a source of instant inspiration through its Factory and User Libraries. You can explore a wide range of presets to immediately start creating. It is also a learning tool, allowing users to open and examine how existing synths and effects are built, fostering deeper understanding of sound design.
For advanced users, Reaktor functions as a powerful development platform. You can build unique instruments to replicate specific sounds or create entirely new audio tools, from generated harmonies to complex feedback loops. The device can then be shared with a community of like-minded creators.
