Source Audio C4 Synth

The C4 Synth brings the complete sound creation arsenal of a classic Eurorack modular synthesizer into a compact effects pedal designed specifically for guitar and bass players. This innovative pedal combines vintage analogue tones with thoroughly modern synthesis capabilities, offering six dynamic synth presets straight out of the box. With unprecedented tracking abilities and lightning-fast response, the C4 essentially puts a full modular synth at your feet, complete with countless sound options and professional-grade performance.

Getting started is straightforward with the C4’s simple 4-knob interface - just plug in and play. When you’re ready to explore beyond the six onboard presets, the free Neuro Desktop Editor (available for Mac and Windows) and Mobile App (for iPhone and Android) open up an ever-expanding library of presets. Browse through the huge collection of vintage and contemporary synth effects created by both the Source Audio team and the growing community of C4 enthusiasts, then simply click the BURN icon to upload any preset directly to your pedal.

The real power lies within the Neuro editing environment, where you can craft your own synth creations using the C4’s comprehensive toolkit. Access four parallel voices, three oscillator wave shapes, ten-plus envelope followers, twenty-plus modulating filters, plus distortion, tremolo, pitch shifting, intelligent harmonisation, FM synthesis, and two programmable sequencers. This extensive collection of synthesis tools gives you complete control to dial in your perfect tone and create truly unique sounds.
