Source Audio SA 249 – One Series C4 Synth


The Source Audio C4 Synth combines all the sound construction tools of a classic Eurorack modular synthesizer into a compact, easy-to-use effects pedal for guitar and bass. Basically, the C4 is a modular synth that offers unprecedented tracking accuracy, extremely fast reactions and almost infinite sound possibilities. For easy plug-and-play use, the pedal comes with six selectable presets that can be selected via the toggle switch. The 128 Factory Presets can also be selected via a MIDI controller. In combination with the free Neuro Desktop Editor or the free Neuro Mobile App, the pedal's true potential is revealed. Via the software you have access to an editor based on Euroracks, which offers 4 parallel voices, 3 oscillator waveforms, 11 envelope followers, 24 modulating filters, distortion, tremolo, pitch shifting, an intelligent harmonizer, programmable sequencing and more. From classic synth tones to all the sounds you could ever imagine - the C4 Synth makes it possible!
