Neuro Editing System

On the surface, the C4 features a simple 4-knob interface and a  choice of six amazing guitar/bass synthesizer effects – just plug-in and  play. If you want to take things to take things a bit further, we urge  that you connect the C4 to our Neuro Preset Editing & Browsing  tools. The Neuro Mobile App is available for free at the App Store (iOS)  and Google Play (Android). The Neuro Desktop Editor is available as a  free download for Mac or Windows systems on our Downloads page. Inside  Neuro you will find the tools to personally create your own synth  utopia. Use the C4’s collection of four parallel voices, three  oscillator wave shapes, ten-plus envelope followers, twenty-plus  modulating filters, distortion, tremolo, pitch shifting, intelligent  harmonization, FM synthesis, two programmable sequencers and more to  dial in that perfect tone.

Let’s  talk a bit about the history of the C4 Synth. Bob Chidlaw (Source  Audio’s Chief Sound Engineer), fueled by his life-long passion for  modular synthesizers, set out to built a powerful synthesizer machine  that would replicate the experience of creating amazing synth sounds  with his own personal Eurorack modular synth. It had to nail the  swelling, buzzing sounds of a real modular behemoth, but it had to live  inside the compact structure of a Source Audio One Series housing. The  C4 is, for all intents and purposes, a modular synth in a box.
