Control the Swarm

Access swarms of parameters with a single control to effortlessly tweak your way to the sound you’re looking for. Morph and randomise your way to inspiring happy accidents. SLOO’s interface has the immediacy of the simplest monosynth married to a huge, complex sound.

A radical new approach to synthesis

SLOO’s revolutionary architecture delivers huge sonic structures, deep animated bass, insane arpeggios and complex polyrhythms. It’s about getting that signature sound in seconds.

Lightning fast transitions

SLOO’s sound can vary from immense density to shimmering filigree in a heartbeat due to its voice swarming algorithm. This allows dramatically morphing sonic transformations, powerful expression in a live performance and flexible control in the studio. Spin the modwheel to morph live from a crisp monosynth into a polyrhythmic chord without the need to grow an extra 30 fingers. Use the Morph bar to transition from a meaty kick drum to a spectral atmosphere without getting lost in endless automation lanes.

A simple route to a complex sound

Voice swarming means high impact and maximum versatility with very few controls. All SLOO’s main sound controls are on one page making the 103 included presets instantly tweakable to get to the sound you’re looking for. Familiar controls such as Filter Cutoff, Resonance, FM and LFO Speed are intuitive to use while sonic richness and complexity emerge from the swarm patterns beneath the hood. Whether it’s a lead, pad, sound FX or a rhythmic sequence you can get to its most modern incarnation in record time.

Made for performance – on or off the rails

Hands-on jamming is at the heart of SLOO and it has a bunch of features to help. If your performance requires razor-sharp timing just hit Live Quantise. If you need SLOO to keep you in key just select one of 4 editable Scales. For experienced keyboard players Adaptive mode intelligently switches between monophonic and polyphonic action. Start a phrase with one key and SLOO plays like a monosynth, start with two or more and it plays like a polysynth.

The depths of the engine – how voice swarming works

Voice swarming works by generating a swarm of variations for each parameter. This swarm is controlled by the centre, pattern and amount controls. Close swarms behave more like a monosynth, distant swarms more like a polysynth. Individual parameters can swarm in different densities. For example the pitches could be very close while the filter cutoffs are far apart. The relative positions of each voice to each other is called a swarm pattern. Swarm patterns can be randomised individually or all at once using the Randomise buttons. The last 16 randomisations are automatically stored and recalled using the History Wheel
