...which allows CV control over sidechain?

Thanks but I'm referring to modules (I hoped that would be clear by me posting it in the 3U section but possibly not for those reading on the forum homepage!!)

With the Cosmotronic Messor you can have an external sidechain in and the CV the SC HPF frequency up to 9k, so if you are using it for kick sidechain or similar applications, you can mute the sidechain. Otherwise, any compressor with CV over ratio essentially has that feature.

what do you wsnt to control with CV? the gain reduction itself? or filtering the sidechain signal?

So the level of the sidechain... So for example, the God's Box Lollipop has a level attenuator for the sidechain which affects how subtle the ducking is. Would be great if you could have CV control over it for some interesting variations in how strong the ducking is.

Checkout the L-1 Microcompressor. It's stereo, with external sidechain input and also envelope out (the "internal sidechain" CV).

Looks great but no longer in production although the website says a new model is in the works! Breaths won't be held, but let's see!

wouldn't running the sidechain signal into an vca before going into the comp achieve this effect?

Definitely email Aleksei and see what he has available at L-1. I think the new compressors are out and still being made, including the bigger stereo compressor with mid side processing (great value for money).

I suppose it could be a good alternative but would require more HP!!

Ah thanks for the tip, I'll also check out the other compressor you speak of!

Not necessarily.. I would imagine that any comp which would have a feature as specialised as this would probably be quite large. You can get 2-4 hp vcas which could be used with any comp with an ext sc input. I’d rather do that and use the best sounding comp than choose a comp based on this feature (which I think is pretty rare tbh).

edit - alternatively wouldnt a cv-controlled threshold do the same thing? It might be more common. I haven’t really checked out comp modules because I have some nice outboard ones, also it’s pretty fun making my own with comparator/envs/vcas/slews which gives insane control over everything, esp with a nice env like contour1.

edit - Schippman cs-8 + any 2hp dual vca = same size as Lollipop you’ll also have a spare vca for more situations like this :tu: I bet it’s a damn fine comp, I have used (and wish I owned) an e+f.

I don't want to hijack this thread but I'd love to know how you build your own. I have a couple Contour 1 modules, a Compare 2, as well as a Rampage. But I have no compressors in my system. Just an outboard FMR Audio RNC1773.

The L-1 midside comp is worth every bit of HP, it’s fantastic.

I suspect this is one of those "there's a reason this isn't a popular thing" type of setups. Usually sidechain is on there for a reason and to occasionally mess it up on purpose would require a different approach to designing a track for it to not sound like some kind of.. mistake. Subtler effects on it for the usual usage in percussion would be probably almost inaudible so a pronounced effect would probably be needed to make it evident. It could be done however, but it sounds like one of various experiments I tried that I was expecting great things from and found to be not all that alluring once patched.

Believe it or not you might want to use a more simple comparator than the C2 - this is a window comparator rather than a simple a>b type (I use the ladik one which also has a hysteresis setting). Anyway the comparator acts as the threshold control. When the audio level goes above the threshold it will put out a gate. Feed that to the envelope. Set the envelope to negatively modulate an open VCA. The amount of negative vca mod is the ratio. Thats pretty much all there is to it at the most simple level. There are many things you can do around that to get more interesting of course.

+1

Build quality is insane like everything from L-1. Mid-Side or Stereo or Dual Mono. Per channel CV over frequency, threshold, ratio, makeup, attack & release of the envelope (which also have outputs each), and sidechain input. For someone considering outboard you would have to spend at least $1000 to get this level of quality, but then you have none of the CV control.

Cosmotronic Messor also looks nice if you simply do not have the space or budget, but I am glad I made the space and budget to get the ultimate.
