Description

The Source Audio C4 Synth packs the power of a classic Eurorack modular synthesizer into a compact, rugged pedal for guitar or bass. On the surface it's refreshingly simple — four knobs, three ready-to-play synth presets, and lightning-fast, near-imperceptible tracking that turns every note into thick, expressive synth tone. Underneath is one of the deepest sound engines ever put in a pedal: four independent voices, selectable sine, square, and saw oscillators, FM synthesis, pitch shifting, intelligent harmonization, a deep bank of filters, envelopes, LFOs, and dual step sequencers. Plug in and play the onboard sounds, or connect to the free Neuro Desktop and Mobile editors to sculpt your own patches and tap an ever-growing library of thousands of community presets. From fat analog basses to shimmering leads and sounds no one has heard before, the C4 is a modular synth that fits on your pedalboard.

    • Get ready to program
Volume jumps broke my ears!!! Hard to set unity gain for all the patches and even harder to do on the fly. For studio use, would be fun if you have the time. EXCELLENT tracking and tones--just don't want to spend hours on the computer getting it all right.

    • Maybe it works from a phone, but not from a PC!
I read the manual before purchase, and it looked like you could specify a note range for (one or more?) the four voices, but did not seem to work. Ugly bass frequencies leaked all over the octaves, creating huge spitting booming sonic messes with simple lead guitar. I play piano style 7 string guitar and hoped it could separate the bass strings, like a Boss OC3 does. Seems like a requirement for any synth, to specify a frequency range for the voice! Returned! Source Audio C4 Synth produces mostly ugly sounds, the cross-over note range function didn't do anything, updated the firmware, then I explored for about 18 hours learning software and editing voices, next day the software couldn't recognize the device, rebooted computer, recognized device but showed only the original 6 voices, closed software and re-opened, the lost voices (downloads and edits) reappeared but the editing software unresponsive and does not change settings when changing voices, but the sounds do change. Enough frustration for ugly sounds. I just wanted to color the sound of the guitar and add bass frequencies (the note range does go down to a limit of 5 string bass (for a seven string guitar) but no effect, so maybe someday? Really did not like the interface; instead of graphic representation of signal flow and waveforms, we get huge dropdown lists of settings with very little percievable difference in effect, but then I didn't thoroughly learn the software. There's also a WYSIWYG option that I didn't dare to try.... Here's an Amazon description that DOES NOT FIT the C4 Synth (seems to pertain to something called Mercury): "Three styles of flanger including Classic Flange, Thru-Zero Flange, and a highly resonant style of flanger called Shadow Flange. Download additional phaser and chorus algorithms or access a deep editing system with the Neuro Mobile App for iOS and Android. Pair the Mercury with the Neuro Hub and save up to 128 presets recallable with MIDI program change messages from an external MIDI foot controller." Only wasted two days on the thing. Good luck. ... show more

    • The most professional synth pedal (period).
This pedal is simply the most professional do everything (album capable) pedal I've ever heard. It's limitless.

    • Noisy and cheaply made
I am returning this product. It is a great concept and editing sounds is great, but it is just too noisy. I even use a noise gate and it is not enough to cut the noise. I cannot use this to perform live when it creates so much unwanted noise. Aside from the noise, the sound lacks clarity. The product seems to be cheaply made. I think a beer can probably weighs more than this pedal. ... show more

    • Inconsistent
Review for bass. Sounds good, doesn't track correctly. I downloaded the neural app and worked with the parameters, use different sounds and combinations, also downloaded different presets, and always found a glitch in the tracking. Used with preamp and without, different attacks and intensity, different notes values, bridge o neck pickup, and there it was a glitch in tracking. I returned it ... show more

    • Broken within minutes
First oh, I didn't get to play with it very long. Because the preset selector switch broke about a day after I got it. But during the course of the first day I can say this. The tracking is awful. Truly awful. Only three presets available at a time you must have a MIDI controller to access your own user presets. And that controller must be USB. Good luck finding that without keeping this permanently attached to your PC. This basically makes it impractical for live performance. I will say it extremely programmable. But due to the other flaws it's not really a plus. The preset sounds that I could actually access were awful. Can't recommend ... show more

    • Mind. Blown.
This pedal is the shizzle! After years of buying lame overpriced pedals in search of the perfect bass synth sound, I found an answer to my prayer! If you're a tweaker, you'll spend your quarantine time in ecstacy playing with the many parameters you can adjust via your PC or phone! Out of the box, it was easy to set up and use, I was able to quickly find a couple of presets to groove with! Definitely worth the bucks! I'll have fun with this for years to come! ... show more

    • Wow
Really, there is so much this pedal can do it's hard to express in a review. The free desktop editor app is a must have as it unlocks the full potential of the pedal with different routing options and effects to apply, but out of the box you can tweak the presets and get very usable sounds. Source Audio is really revolutionizing guitar/bass effect pedals. If you go with full MIDI implementation the possibilities are almost endless. Also, Chicago Music Exchange was the perfect vendor - quick shipping and no hassles. ... show more
