I added a KVR attachment to download it. I avoided this just so people could DL it even if they aren't forum members.thecontrolcentre wrote:Would love to try this, but the d/l link is crashtastic here... I click download, get re-directed, then the window closes (mobile win explorer)

Sorry for delay if anyone was expecting an update. I've been figuring out how to add a sidechain in a way that makes the most sense, I think I've decided on it. The sidechain mode will just directly control the sensitivity parameter, making the knob non-operational. Will have it out within the week!

Thanks for the update!
Could you expand on what to send to the side-chain input though? I'm having sone success with a waveshaped version of the original audio but don't really grasp the concept here.

What to send to the sidechain, just try anything
A waveshaper is a good idea, I use the FL studio one, it allows to reshape the transfer function for both positive and negative inputs.
The sens control follows a basic rule, for each change of 1 of the 2^x reading, or in SC mode, each division of 1/16 of 1.0 gain (0dBFS), the threshold of the slew function changes by an octave. So if you were to change the sens control from 5 to 6, the theshold would decrease an octave. If your sidechain signal goes from 0.2 to 0.4, it may seem logical to say the octave also diminishes, but it doesn't, because the input of the sidechain isn't peaking at 1.0. So for the sidechain to act normally at different input gains, it must peak at 1, even if the signal input doesn't. This is because it's not a logarithmic control, it's linear. To reiterate, if the sidechain doesn't peak at 1 (unity gain), the slew sensitivity doesn't change as much. And, as signal gain increases, the slew function cuts off more signal.
I don't have any examples to offer since it's all very delicate and related to the actual signal going through it. But I will post a screenshot of how I set it all up in FL studio to allow easy control of the gain structure.

This image shows how to make a routing to use the FL studio mixer faders to control the gain staging. In this example I also make an envelope follower using the effects on the sidechain. The waveshaper with the V looking curve is just a rectifier, and it also shows exactly how the rectifier built into the plugin works.

I absolutely love very strongly non-linear and 'irrational' distortion, and the sidechain is taking this thing to another level in that department. Got some lovely results on drones, rhythmically corroding them using drum loops in the sidechain.
Nothing else in my plug-in folder sounds quite like this. This is proper secret weapon stuff for me.
Many thanks for sharing.

Sorry for the late thanks and i agree, lots of potential here for grimey sounds.

I use it a lot as a gentle shelving filter with the mix control. It tones down the treble in a more dense and distorted way than a normal filter.
There will be at least one more update to finalize everything (code-related). That one will also add a mix control parameter smoother, which I forgot. It may contain new features also, if I can get them to work. Some tests showed instability with some settings and I don't want to release that, obviously.
