Audio examples

Nucleus SoundLab's first RE is Beat Crush - the ultimate bit crusher. By default Beat Crush adds a subtle 12-bit crunch to samples reminiscent of classic samplers. But it's also extremely flexible - users have access to each individual digital bit to create completely unique custom distortions!

Beat Crush is much more than just a lo-fi effect. Two very powerful multi-mode filters are onboard, and can be configured in a huge variety of ways courtesy of a semi-modular architecture. Using these features in combination, users will find easy access to crispy drumbeats, dirty dubstep basslines, creative vocal effects and more.

Product details

Nucleus SoundLab has long been a leader in Reason ReFill market. With Beat Crush, they have finally brought their unique Reason expertise to Rack Extensions.

Beat Crush is a fully-featured multi-FX device, but its central feature is the customizable bitcrusher at its core.


By default, any audio you run through Beat Crush is crushed down to 12-bit. This adds a very subtle crunch that sounds great on drums and is reminiscent of classic samplers and drum machines from the 80s/90s.

However, the possibilities for creative FX grow exponentially when you use the array of Bit Buttons across the bottom of the device. With these buttons, you can turn on/off/invert each of the individual 12-bits. This leads to a near-endless number of custom distortions available.


To complement the bitcrusher, Beat Crush also features two advanced multi-mode filters. What's most exciting about this addition, is that the filters can be arranged in the signal path in five different ways. Three serial modes and two parallel modes are available. The parallel modes even allow stereo panning of filters for wider sounds!

Modulate Everything

Beat Crush features an onboard LFO and Envelope for very quick modulation of the most important parameters. In addition to that, nearly all parameters are modulatable via CV. Going even further, many controls are modulatable via MIDI for live performance purposes!

Pure Quality Patches

Beat Crush comes packed with 82 Combinator patches that meet all the usual Nucleus SoundLab high standards: Each Combinator has unique rotary, button, modwheel and even pitchwheel(!) destinations; Combinators are categorized across four folders for easy access; 108 device patches that make up each Combinator are also available; and all patches have been meticulously volume-balanced to fit into your mix instantly and not offend ears or blow monitors.
