Hi, Janek. Thanks so much for checking out the C4, and thanks for your honesty. I'm puzzled why you weren't able to turn on the fourth voice, I could see from the video that it was turned on and then you turned it off - perhaps the Level of the fourth voice was turned down or maybe it was routed to the second stereo output. Regardless there are FOUR available voices plus the dry signal that can all be mixed together and each voice can be routed to either side of the stereo split. Yes, you are correct that you can only use two sine wave oscillators at one time, beyond that you would need to bring in a square or saw wave oscillator, or one of the monophonic pitch shifters - maybe adding a couple of the monophonic pitch shifters instead of the square wave would have brought you closer the sound you were trying to achieve. You definitely touched on one of the common criticisms of the C4 - the simple hardware masks the massive number of options offered by the Neuro Desktop Editor. This was a challenge that we were well aware of going in - we knew that we wanted a very simple to use pedal out of the box, but also wanted to offer all the options that we could fit into the firmware (20 plus filter types, several envelope options, two 16 step sequencers, pitch shifting, intelligent harmonization, multiple types of distortion, LFO modulation, pitch modulation, FM synthesis, etc). Deciding on only six default, out-of-the-box sounds was very difficult - basically it was impossible to pick six sounds that would satisfy everybody, so we resigned ourselves to the fact that using the Neuro Editor was essential to the C4 experience. Basically we are hoping that people will use the tools available to them to build themselves the perfect synth pedal. And please don't forget that there are many, many very talented C4 owners out there that are helping us build a massive library of great presets in the Neuro Editor. These presets can be very easily auditioned and/or burned directly into the pedal - so if programming sounds is not your thing, there are tons of great sounds available with one click. And finally there are up to 128 preset positions that can be accessed via MIDI. Sorry to ramble on so much, but as one might suspect, I have a lot to say about this pedal (and I've only said a small bit of what I would like to say, but nobody wants to read that. - ha ha). So again, thanks so much, Janek - it was a lot of fun to hear you play through the C4. We're happy to answer any questions you or anybody else has about the C4. This pedal represents well over a year of intense work from our two man engineering team, so we want to make sure that everybody understands what this pedal is capable of.

Thank you so much Janek. Its SLIM pickins for videos that demo pedals on bass. We need all the demoers we can get. More, please!

I recently got this pedal for the pop gig situation like you suggested. I did find a few solutions to some of the issues you talked about. The pedal can be programed to switch preset banks by holding the footswitch down instead of the button on the back, I found this very helpful. It can also be hooked up to a midi footswitch to program a lot more than the 6 presets accessible on the pedal itself.

I love the C4, great synth pedal!

Im so glad i found your channel thanks to Vertex Effects. I love playing guitar and bass, but that past 5-6 years have been dedicated to building my guitar pedalboard. Now im building a bass board and u have sold me on the idea of using the Source Audio C4 and the Meris Ottobit Jr. I dont have those pedals yet, but im definitely going to get them in the future. Love the capabilities they possess. The C4 is so powerful, but also is daunting since i dont have much synth programming experience. It will be fun to learn though.

I just one of these , amazing pedal, finally a pedal with he depth of parameters I’ve yearned for , for literally 10 years

Enjoy these reviews also like your personal opinion. Please keep these going it’s great to get your honest input on pedals

The stock sounds on this pedal aren’t great and it *does* take time to craft your own in the app, but once you’ve got some you like you can save them to the pedal so you aren’t limited to either the stock sounds or being perpetually stuck in the editor. Janek’s right in that it’s not great as a live pedal you can physically change the parameters on, but I recommend Zachery Rizer’s review as an alternate perspective; nothing against Janek, I love his playing and content, but watch Zach’s video before making your mind up, he gets some amazing sounds out of it.

I use this with a midi controller. I never turn it on with the switch it comes with. I don't even touch it anymore. Totally different kind of pedal. Full digital app on computer is the tweaking paradise i wanted. I 'dial' in my sounds and program my midi controller and i'm set.

the best pedal in my life

Love the demo! I am considering this pedal. Thanks

Hey Janek: Thanks for the props on my Future Nostalgia patch, and it sounds SICK with the reverb! One thing that I haven't seen mentioned so far... Adjusting Neuro Community patches to your personal gear/playstyle is pretty much required. In this case, you could up the sensitivity of the sound and change the envelope to get more swell and have it be less abrupt (there's even an envelope called "Swell" that does exactly that).

Interesting I’m gonna have to have a look at some of the users presets That sound at 21:50 is great Reminds me of the blade runner sound on the korg minilogue synth Thanks Janek , your awesome

I loved your description of how you saw the pedal in context! It very much seems like a software synth that effectively turns your bass into a MIDI controller. I really liked the patches, and the tracking on it is impressive! While it doesn't seem like a great solution for changing parameters on the fly in a live setting...I wonder if it will become part of the "Post-Apocalyptic Future Baby Elephant" sound? 😁 Fantastic video and great job, as always!

Agreed on all counts man. Great video brotha. If anything it make me want an H9...lol

I have to stronglt agree with you in the way how the application is necessart for changing sounds, I cannot see how in a live enviroment with no extras it can give that much of opportunities. But, there are controllers for the pedal that extend a lot the sounds. Because of the tracking in might not be that good vor sooloist things, but for somthing like you made in the end I can relate. AWESOME, CHEERS Janek :D See ya in Twitch

Best part of C4 is that it can turn your guitar into any bass imaginable...

I am going to absolutely Buy This pedal soon

Great video. FYI - You can choose to have the second 3 memory spots accessible by holding down the foot stomp button for a few seconds. Then you don’t need the button on the top.

Been waiting for this one! Nice!

The reason you couldn't hear your 4th voice is because the level for it was all the way off. And it didn't track as well as it could have because you had the "high note" of the Pitch Detector set to E6 (guitar with 24 frets) yet you're playing a bass with 28 frets. Also, adjusting the Input Gain can improve tracking (or rather, ensure the Envelope sensitivity is accurate); it has to be set just right depending on your instrument's signal. The reason it didn't sound as fat as the H9 is because you were cutting the Bass EQ, boosting the Treble, and had the Output Volume very low....not a fair comparison...just saying. Not your fault, just correcting you like you asked. In regards to more than 2 voices per waveform, it really wouldn't change the sound much. Compare a single waveform to 2 of the same type....it's the same sound. What does fatten that sound though is adjusting the Detune slightly and/or using the Modulate option. If you do that then 2 voices is plenty for any one waveform, which is why it's designed the way it is. Four voices in a proper synth is actually very generous (not all that common really), let alone in a synth pedal.

Representing Dr. Um!

I love this intro so much

You keep making these videos!

Great video man

Awesome intro... JG!

👍👍👍

Janek is great. Very knowledgable and honest. We are lucky to have people like this in our life. C4 is also amazing

I love how you went into more generic terms explaining this pedal but also other pedals with tracking and special sounds... I got a Electro Harmonix bass monosynth... it does wierd jumps in tracking it's a learning experiment, teaches me to avoid those extra harmonics / string noise... but works amazing with a distortion pedal(then a wah wah) after the signal, destroys everything... I need to try reverb like yo do near 21 minutes with the EHX have you tried 2 C4s in a loop ? you know... have 1 C4 track the other.... and maybe have the 1st C4 track the second one that is tracking the 1st one... could turn into a "music machine" with right settings such as sequencers(if the C4 has it) etc

Nice shots with the caps in the background

When will you be reviewing the boss oc-5?

for harmony, a pro like you should probably have an FM3. Sadly there's nothing cheaper than that on the market that can track well, and get good diatonic polyphony, and it also allows for user-created scales for the harmony - a feature Eventide could offer on the H9 but refuses to in order to justify the existence of the H9000. Source and Meris could also offer custom scales on the C4 and the LVX with just a software update. It's not a hardware issue. It's a user interface hassle.

I might be wrong, and this may not matter based on the placement, but I think you get another 4 parameters after you hit the alt button on the back.

Comparing 🍊 and 🍎

How were you getting the sounds from 3:45? They aren't part of the preset

21:15 Mass Effect launched

That 'Future Nostalgia' patch has John Carpenter written all over it.

21:00 - Subdivisions, anyone?

Hello! 👋

What Pedal is using at 16:05?

Seems like for some sounds like the long sustained cinematic stuff it would actually be better to have it before the volume pedal. That way you have volume control but the pedal is always getting full signal.

YAH PULL WAY TOO MANY MASTERBATION FACES TO TAKE YOU SERIOUSLY! BUT at least you are honest.....

I know you said that this wasn't a review, but it felt like you only made the video to shut people up and to say that you tried it.

Pff, all the reviews of the C4 are unprepared knob-turning videos that have nothing useful for playing.
