WMD C4RBN - New state variable filter/wavefolding

Post by Macro/micro » Thu Jul 09, 2020 12:23 am

WMD keep killing it with these enticing little modules! I'll be curious to see this one in action (as well with the other new one, Javelin, which I'll make a separate thread for).

COMING SOON
C4RBN (pronounced "Carbon") is a 4/2-Pole State Variable Filter with input saturation, output wavefolding, and more. It features a wide range of character from nice and clean filter sounds to screaming, squelchy, acidic mayhem.

C4RBN builds on WMD’s history with state-variable filters (uHadron Collider, Protostar, MMF) adding interface refinements and improved warm environment stability for live performance and beyond. A novel input saturation circuit plus the output wavefolder from WMD’s classic SYNCHRODYNE filter pair together to push the timbral flexibility to the next level. C4RBN is the building block to life in your eurorack.

Highlights
- 3 independent 2 pole outputs for High Pass, Low Pass, and Bandpass
- Inverting Attenuator (attenuverter) for FM allows for positive and negative CV control over the cutoff frequency
- Independent 4 Pole output with switchable frequency response
- Input Saturation with 3 switchable levels and CV input for additional fine control
- PING circuit generates a fast decay envelope emulating the response of a vactrol
- Output wavefolder for extra bite and screaming character
- Resonance with self oscillation
- Temperature compensated 1V/Oct tracking.
- Performance focused control scheme allows for on-the-fly changes of filter types with intention

Specs:
Size: 4hp
PCB height: 112mm
Depth: 38mm (with cables)
Power: +92mA, -82mA
Audio Input: 100k ohm impedance
20Vpp range
V/Oct Input: 82k ohm impedance
Temperature Compensated
CV Inputs: >100k ohm impedance
Filter Outputs: 1k ohm impedance
20Vpp range

92 mA +12V
82 mA -12V
0 mA 5V
38 mm deep

Looks really powerful for the hp, great work!

Looks like an upgrade to the WMD/SSF MMF. Nice features. I hope it sounds similar too.

MMF was on my list. this looks like an upgraded version of that! I hope it sounds even better cause the MMF sounded so so good for pings and even filtering ;)

question though: is it saturation or wavefolding? or is it saturation, wavefolding, or both?

There is a saturation circuit on the INPUT. This is a nice, subtle saturation that just makes the overall tone a bit more warm. As it is on the input, the effect is heard on all outputs. The Wavefolder is on the OUTPUT of the 4-Pole Filter only. It can be switched on and off. So yes, it can be one, the other, or both!

Looks really interesting! I was also about to pull the trigger on the MMF but guess will wait a while

As I said in their insta when I saw it announced, this thing is the answer to several prayers for me! Perfect feature set at precisely the right size. If it sounds half as good as it looks on paper, I'm SOLD.

I thought I had more than enough filters. But it’s only 4HP...

I was like 90% certain I was going to buy this before I saw this demo. Now... More like 110%. I'm real excited for this one!

Damn, this kinda makes me want to sell my HN VCF. C4RBN has a competitive feature set in a slightly smaller footprint.

Also looking for someone willing to make a couple small changes to Rings firmware

Is it DC coupled? I'm looking for multimode filter for envelope shaping duties in addition to filtering and this would be perfect in only 4 hp.

Yes C4RBN is fully DC coupled.

Nice demo! Seems like there’s a nice balance here between a really classic flavor of filter and all the great ways you could freak it.

Placed my order this morning, told they could be ready as soon as end of the week! (Not counting on that, but I'd be very stoked of it turns out that way, since my family is going away this weekend and I'd have three days to fall into a deep modular wormhole!)

Hey y'all, here is a demo of 1V/Oct key tracking with C4RBN. Love this thing!

Are these on track to have been shipped to vendors on the 20th last week? Everywhere still seems to be in pre-order.

We just started shipping a few units last Friday (24th of July), we had a potential COVID case and had to shut down shipping until tests came back (all negative fortunately). We're on track to ship this week.
