source audio c4

The AS has internal mixing and switching options that we hide from you and present them as a high level list of routing options. It makes sence in a distortion box. In the C4 you get access to all the input and output routings and when used with the voices, you can create a huge list of routing options for yourself. I would suggest studying the Desktop Editor. It's very flexible and powerful.

Thanks - really appreciate you getting back to me on this!

As I don't own a C4 (currently just the AS, Manta and Neurohub so far!) would I be able to make any sense of the Desktop Editor for the C4 without having the actual C4 pedal to hand?

You can view the C4's editor in the Neuro desktop if you select the offline editor of that pedal.

I think all of the parameters and drop down menus are given straightforward labels and names. If you download the C4 manual from the website while skimming over the Neuro editor you should have no problem understanding programming the C4.

Parallel loops - does the C4 provide for this?

Guys - it's not clear to me from from the C4 manual whether the C4 provides for parallel looping with other pedals?

I have the AS and it seems to me that the AS manual is pretty clear on this - it can do a series loop but not a parallel loop. The two inputs / outputs do allow for stereo in / out and can also act as a splitter for a mono input. But the loop function on the AS (from the manual) is a much less useful series loop and when the AS is bypassed, the external effect will be out of the circuit and inaccessible.

Just wondering whether the C4 is the same as the AS or provides for additional parallel looping?

I've been considering what the positives and negatives are with the loop.

On first blush, using my fuzz in the loop gets me the option of having that drive my filters, should I choose, or I could just have a patch or two set up to give me straight up fuzz variants. I could also run synth into that fuzz for a further range of sounds.

Downsides would be that if I want to use the Neuro App on my phone I have to pull part my loop setup to make that happen, and/or it would mean I'd have to carefully police and edit any patches I load onto the C4 to make sure that they're not errantly set to accept input on both 1 & 2 when I don't want my Fuzz to be routed in...
 
Excellent thank you - so just like the AS (which I guess I was expecting). I'm guessing that this will also be a series loop, like the AS, rather than a parallel loop?

Actually, right now I am not 100% sure if you couldn't do parallel loop. You can route input 1 to go to output 1 AND 2 (the latter routed out dry to external fx). Then input 2 is routed to output 1 as well. Please, anyone, correct this if wrong.
 
Cheers @Annette - yup the SA C4 manual was my starting point before my first post earlier today.

Out of interest does that answer the question for you? :laugh: Have to admit, it left me none the wiser! But hey I'm just a bass player...

Love someone who has a C4 (Source Audio?) to be able to simply say "yes" or "no" it can do parallel loops, and if it can, that they have successfully set it up on their boards to do so. Thanks for being patient!

Ok just opened the External Loop Template - which is set up to do serial loop. If you use the processor pan to go to Output 1 at the same time as Output 2 (aka parallel loop) your return signal after the external fx will go through the same processor 2 settings as your dry signal. So while parallel routing is possible, it won't be really useful.

You can create a loop but this routing will be bypassed when the pedal is bypassed unfortunately.

But there's nothing stopping you from designing a patch (easily, based on maybe the Bass Initialize patches out there) that have literally nothing going on where you could pass whatever is in the loop right on out the other side. Then you just load that and trigger it.

Totally. But I also agree with you on realizing the added work of having to reroute all kinds of user patches. I decided not to do this. :)

It seems inelegant at best, if not a downright pain in the @$$.

I do have a loop/switch unit (ES-5) and now with the C4 taking the place of a number of pedals, I'll probably opt for keeping my fuzz in a loop, the C4 in a loop then having some control over how I apply stuff. I can run the C4 with fuzz in front of it and keep a clean parallel should I desire. Then I can use the high pass on the Filter to pull it up and leave lows clean and intact. I had hoped to keep the C4 out of the loops because it allows me to scroll/trigger with my DMC easier, but I'd just set up a ES-5 patch that's C4 without any MIDI command and use the DMC to do the rest.

But if you have a patch with literally nothing going on, doesn't that mean you can't be using your C4 as a synth at the same time as the other effects in parallel? (Which is the whole point of a parallel loop for me). Or am I missing something obvious?

Yes. We were discussing the ability to use the looped effect by itself rather than with the C4.

This should be correct.

It's nice to have full manual control over which input goes to which output with the C4. This wasn't necessary with the Aftershock but it's really nice to have on something like the C4 which basically is a 4 channel multi effect pedal.

Not necessarily.

One of my presets is an Octave Down preset. This replaced my MXR BOD. It utilizes 2 of the 4 voices in the C4 to do an sub-only octave down effect.

In addition I have one more voice "Mono Input" routed in parallel with my Mastotron feeding the Input and then leading straight to the output, unprocessed by the C4. In the control settings I've set one of the assignable control knobs to control the volume of this voice only. This effectively allows me to use the preset as a sub-only octave -1, or as an octave -1 parallel to my Mastotron Fuzz.

Like @BurningSkies mentions you are able to route each voice to isolated outputs or to a combination of the outputs.

In my example I'm sure I could program that octave into let's say a volume swelling Saw tooth Synth voice with a 5th harmonic and still run Mastotron parallel.

Great info all around in here!

I'm thinking along these lines.... if I get a DMC.micro, plug that up to my Meris Mercury7 via 1/4", and then pick up a SA C4, I ought to have control over that via USB from the DMC.micro, yes? That'd be some snazzily compact modularity. And then, connect 5-pin from my PC (via a DMC y-cable) to edit presets?

I'll research the DMC.micro a bit more to ensure it can tx on both, and not either/or.

Here’s the email I got!
Hi there! What firmware version are you running right now? We do have an updated beta that should work better with the C4, I’ve linked it below:

Dropbox - DMC_MICRO_104b.BETA.bin.zip - Simplify your life

Firmware update tools are here:

disasterareadesigns.com/files

And here’s a video showing the update procedure with the MIDI Baby. The steps are the same with the micro, except you must hold down the LEFT footswitch while inserting the USB cable to start the bootloader.



This version changes the program select method for the C4 to use MIDI CC rather than program changes, which are currently broken on the pedal.

Please let me know if this helps! It’s working great on my board, I hope it gets you up and running!
