Blocks combine the freedom and flexibility of modular patching with the trademark DSP quality of REAKTOR. Over 40 feature-rich Blocks are included, offering limitless inspiration and sonic creativity. Load as many oscillators, filters, effects, modulators, and sequencers as you need to patch your dream modular rig. Use Blocks to connect to your hardware with advanced CV and MIDI connectivity. Read on to get the details on the full range of Blocks.



REAKTOR 6 ships with 14 patches designed by modular synthesizer experts. The patches range from generative sound machines and classic subtractive synths to experimental devices only possible on a modular system. Each is an incredible synth on its own, giving you the flexibility and unrivaled power of Blocks in an instantly playable package.

Ready for use with KOMPLETE KONTROL S-Series keyboards and MASCHINE, these patches are the perfect starting points from which to modify and tweak until you’ve designed your own custom synth.


The REAKTOR Blocks 1.2 update introduces new CV and MIDI connectivity. Calibrate pitch signals for accurate use with external hardware oscillators, use Blocks to convert any signal into gates and triggers, and send pitch, gate, and modulation signals from a Blocks patch to REAKTOR’s MIDI out.


The release of Blocks 1.1 introduces nine new Blocks and five new patches. West Coast Blocks are inspired by Don Buchla’s unconventional and playful approach to synthesis. Macro Knobs and Macro Switches make it easier for you to control your creations on KOMPLETE KONTROL keyboards and MASCHINE hardware. Bento Box 4-Mods complements the 8 Steps Sequencer with four sequences for modulation. And the Bento Box Xfade and Rounds LFO deliver useful functionality that will enhance any patch you create.
