Source One C4 Synth

• Six Preset Positions: Use the C4’s three-position toggle switch and two preset banks to save six easily accessible presets.
• 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.
• Compact Design – The durable, anodized aluminum housing has a small footprint and sturdy hardware. Dimensions: L: 4.5 in./11.4cm x W: 2.75 in./7cm x H: 2 in./5.1cm (including knobs).
• Universal BypassTM – Select either analog buffered or relay based True Bypass.
• USB Port - Class compliant USB-MIDI allows the C4 to work as a plug-and-play device with recording software running on Mac and Windows recording software or any third party MIDI controller with USB host. The USB port also offers connectivity to the Neuro Desktop Editor providing access to deep editing possibilities and pedal firmware updates.
• ​External Expression and Tap Tempo Control — Use the Control Input jack with the Source Audio Dual Expression Pedal (expression control to multiple parameters) or Tap Switch (adjust LFO rates on the fly).

The C4 Synth responds to MIDI Program Change (PC) and Continuous Controller (CC) messages via its mini USB port. The USB port handles communication between the C4 and digital audio workstations (DAW) on Mac and Windows machines as well as external MIDI controllers with USB host support (we recommend the DMC.micro from Disaster Area Designs)

• Preset Saving – Save up to 128 effect presets.
• MIDI Mapping – Use the Neuro Desktop Editor to easily map MIDI Continuous Controller (CC) messages to a comprehensive list of parameters.
• Preset Recall - Use MIDI CC numbers 103 & 104 to recall any of the C4's 128 MIDI accessible presets.
• MIDI Clock – Sync the C4's LFO rate with external MIDI clock messages.
• The Neuro Hub - Connect the C4 to the Neuro Hub and use MIDI CC messages to control parameters or recall presets.
  ​Note: As of Hub fw 1.18 and C4 fw 1.14, the C4 can now be added to scenes, is visible through the Hub, and can be controlled by PC messages, giving you the full access to 128 preset slots. 

The Neuro Editing Systems

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.
