Browse, Burn, and Play
βIt’s that easy. When you're ready to explore
beyond the C4's six onboard presets simply jump to the Neuro Desktop's
Cloud tab or the Neuro Mobile App's Browse function and check out all
the available presets created by the Neuro Community and the Source
Audio team. We've got a huge and growing-huger collection of vintage and
contemporary synth effects that are guaranteed to amaze. When you find
that mind-blowing tone that you can't live without, simply click the
BURN icon and upload the preset directly to your C4 - it will be waiting
for you at the next gig.
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 and . The Neuro Desktop
Editor is available as a free download for Mac or Windows systems on our
. 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.
Dive into the C4 Neuro Sound Editor - it's good for the soul.
