Source Audio SA 249 One Series C4 Synth

Source Audio SA 249 One Series C4 Synth

Modular synthesizer effects pedal for guitar and bass. The Source Audio C4 Synth unites all the sound construction tools of a classic Eurorack modular synthesizer and packages them in a compact and easy-to-use effects pedal for guitar or bass.

The C4 offers multiple methods of preset storage and recall. For a straightforward plug-and-play experience, simply select one of the pedal’s six onboard presets with the center toggle switch. The addition of a third-party MIDI controller with USB host provides access to any of the C4 Synth’s 128 Factory presets.

Connect the C4 to the Neuro Desktop Editor (a free download for Mac and Windows) or the Neuro Mobile App (iOS and Android) and unlock the pedal’s true power. The Neuro software features a Eurorack inspired editing interface with 4 parallel voices, 3 oscillator wave shapes, 11 envelope followers, 24 modulating filters, distortion, tremolo, pitch shifting, intelligent harmonization, programmable sequencing, and more.
