I got the c4 last month and it is awesome and overwhelming and inspiring.
I love testing out the different presets in the cloud and experimenting with my own. I have only a whisper of a clue at what I’m doing, but I can still make some interesting sounds.
If you don’t end up using synth every song, you can still program in some different filter or fuzz that you need for other ones.
I highly doubt you’ll regret the purchase.
I agree about not regretting the purchase. The C4 has to be one of the best "bang for your buck" purchases out there. Plus it's just plain fun.
A couple of pro tips to help get you started programming your own patches:
1) Youtube has a wealth of knowledge to help you get started with synth... That's how I got started with making my own patches on the Future Impact, and the knowledge carried over to the C4. Search for things like "synth tutorial" or "synth sound design" to get started down the rabbit hole. Also handy to know: "ADSR synth tutorial" (Attack Decay Sustain Release). Most videos will be synth KEYBOARD related, but you can transfer the concepts to the Neuro Editor pretty easily.
2) Start by checking out each voice, one at a time. Get to know what each one sounds like and how it behaves. That'll give you a good head start, and then you can start mixing and matching.
I’ll add that the main bummer with my G5 is the bypass isn’t great.
The G5 has an awesome octaver. The tracking is fantastic.
Put a OC2 in front of all the fuzzed our settings in a G5 and the fun really begins.
This is a good point about the C4: It's not "just a synth." It's an multi-voice envelope filter, it can do the standalone OC2 sound quite convincingly, has some nice dirt options, and I think there are some people that have figured out some nice phaser type sounds too. To be fair, the Future Impact has some really great "not just a synth" options in it as well, too.
How do you only choose 6?!![]()
My C4 is probably my "if you could have only one" pedal. Synth, envelope filter, OC2 (and other octaver sounds), and dirt options... I don't think I could ever narrow down to just 6 patches!

It hasn't been mentioned yet in this thread, but the C4 can also load envelope filter patches from the Source Audio Spectrum as well, so that's even more patches to play with from the Neuro.
I currently have 56 of my own patches loaded (for various cover band songs or just for fun), and another 40 or so from the Community to "check out later." Not counting the curiosity patches from the Neuro, I could probably cull the herd down to 15-16 patches. lol
