F.’EM
11-Operator FM Synthesizer

F.’em is one of the most powerful FM Synthesizers ever made, taking advantage of modern CPU resources to process its freely configurable 11 operator matrix. It’s a hybrid quad-timbral synthesizer that can function as an FM, VA and Sample-based instrument, with the added bonus of a dual multimode filter, a complex effect section and an incredibly flexible modulation matrix.

BIOTEK 2
A powerhouse sampling and synthesis workstation

BioTek 2 offers boundless sound design in a unique and inspirational environment. Not only is its engine more capable than existing offerings, but the choice to use natural and environmental samples gives the instrument its unique character. Extensive modulation and modifier routes are intuitively assigned and all parameters are available for DAW automation. Dive into the weird and wonderful immersive world of BioTek.

WAVERAZOR
Futuristic Virtual Synth

A futuristic synth that gives you the power to splice waveforms into aggressive new sounds. The patented oscillator design utilizes a new form of synthesis to produce biting leads, glitched-out basses, cinematic pads and everything in between.

ABYSS
A visual synthesiser with character and a bit of fairy dust

Based on spectral synthesis, Abyss adopts a unique approach by representing sounds with colours making it intuitive and instantly inspiring. It brings to you dark, vibrating drones, vivid cinematic pads and rich evolving textures. With Abyss you find instant inspiration for your music and sound design projects.

HYPERION
Multi-layer, Modular Synth

Hyperion synth has been designed from the outset with sonic flexibility in mind whilst keeping modular patching approachable and easy to follow. Efficient processing enables up to 10 layers of complex sound patches providing An unlimited sound design playground inspired by 80’s legends such as Vangelis, Jean-Michel Jarre and Brian Eno. Hyperion is a contemporary digital modular masterpiece.

SPACECRAFT
Deep granular synthesis

SpaceCraft is one of the most creative and inspiring granular synths ever made. Based on the hugely popular iOS app it’s well known for providing instant gratification and stunning, unique sounds. Two parallel granular engines provide grain frequency/length control, sample position LFO, stereo reverb/filter and pitch/ring-modulation. The innovative grain pitch sequencer, MIDI / MPE and live sampling capability open up further depths of performance and expression.
