Synth by Rob Papen

Buy and getFREE

QUAD was the first-ever Rack Extension synthesizer built from the ground up for Reason by the Rob Papen team and is now also available as VST/AU/AAX plugin. 

The sonic palette is huge, through the vast modulation possibilities that QUAD has to offer. The sound sculpting tools start in each Oscillator and are the Phase Distortion and WaveShaper. These tools are brought to life by 2 XY-Pads in each Oscillator, which can be moved through an extensive modulation matrix.  QUAD’s Oscillators are complemented by two top-notch analogue-modelled Filters, which have different routing options, an arpeggiator, and two high-quality effects processors. 

Welcome to the new refreshing synthesizer QUAD – not only available in Reason but available to all!
