Growing Library of Published Presets: For quick access to a world of great tones, try sampling sounds from a vast collection of published presets created by the Source Audio team and the ever-growing C4 Neuro Community.

Unprecedented Sound Sculpting Options: The powerful Neuro Desktop Editor (Free download for Mac and Windows) and Neuro Mobile App (iOS and Android) offer maximum sound exploration possibilities. Use Neuro’s modular synthesizer inspired editor to create custom C4 Synth presets that can be burned directly to the pedal, saved to a private cloud based library or shared publically with other members of the Neuro Community.

Supreme Tracking: If tracking matters to you (and it should), you will be amazed by the lightning quick, imperceptible latency of the C4 Synth.

128 MIDI Accessible Factory Presets – The addition of a third party MIDI controller with USB host provides access to any of the pedal’s 128 Factory presets.​

Stereo Inputs and Outputs: Use the Neuro Editor’s panning controls to route each Voice to any location in a full stereo spread.
