Super Strange Sidechain Moves?

Super Strange Sidechain Moves?

I’m wondering if anyone does anything wild with a compressor’s sidechain insert.

Not the regular old eqing the send and returning it back so the detector hears the same program but filtered.

I mean like strange....

Anyone use the insert send for something else entirely? Perhaps not even returning it? (I know sounds silly) stranger things have happened though

Or any interesting processing to the signal before it’s returned?

Perhaps delaying it a bit?
Gating it?
Compressing it?

Just a thought

Have a good weeek

Compressing/limiting the sidechain would basically give you a gain reduction limiter like in Elysia compressors.

Here‘s one that could be fun: run the sidechain through an expander!
Might make for some pretty unforseeable compression.

cool
yeah thats something to try! expand it....

could you explain how compressing it would get you close to the elysia? the xpressor i assume?



also when i said delay i didnt mean echo, i meant just shifting the signal

Since the sidechain tells the gain control what to react to, limiting it would also limit the gain reduction being applied. So signals wouldn't be compressed more than x dB, even when they exceed the threshold even further.

Run a metronome into the sidechain.

You don’t have to run the same channel / source that you are compressing into the side chain. Solo kick would be an example but there are no rules so have fun experimenting. You can run the side chain source through an effects processor before hitting the side chain but you may have to adjust for latency.

Sidechain compress a drum group’s verb bus (100% wet) to kicks or simple rhythms. Try it.

Also... sidechain with an EQ to Sidechain compress only one frequency on an instrument to a competing instrument. Makes vocals gently pop out from dense accompaniment when things get too messy. It sounds different than simply riding a fader.

Put a compressor on something and Use a dummy VI track’s piano roll to trigger sine waves that duplicate another track. Delete the sine track after you Print the compressed audio. This allows you to trigger the compression on the desired notes while still having midi velocity to change threshold amount throughout the track. You can now sidechain a bass with the ability to alter note length and velocity independently of the source.

Anybody take the sidechain send and use it elsewhere?

What for?
That would be the exact same signal as the input.

Yeah and I assume not the same quality you would want from your audio outs.

Yeah what for?!?

I guess I’m hunting for one of those stories where someone magivered some roundabout problem by snagging that signal. I can’t imagibe what.

I normally drive side chain with dedicated track to have more control to its behaviour.

I have been complaning for some odd years now about companies not offering true Sidechain inserts on their compress's, but all in vain it seems. :(

Agree. Especially on really these really colorful ones that keep being released. It’s a wasted opportunity to add big value at relatively little cost.

Any examples?
My RNLA has sidechain. My Bastebis proeceasor had it. I guess I would love it in my chandler Germaniums now that I think about it

Maybe the link works for that?

I had a distressors years ago I can’t remember if it had sidechain or not

My fatso did. But I rarely used it

I should use it more

Anything to get myself committing and moving on

What for? One possibility would be to feed the sidechain out into another dynamics device that's being fed by a different signal. Criss-cross the sidechains, duck signal A whenever signal B is loud, key signal B to be even louder whenever signal A is loud. I've never done it, but now I'm curious to try it out.

Somewhere on this site, long, long ago, people talked about the old school ways of doctoring drum recordings before sampling, using gates: feeding the kick into the sidechain input of a 150 Hz or 250 Hz tone generator, so that you get either "whoomf!" or a more high-pitched jazzy kick or whatever at a more consistent level and feel; doing the same with white noise for a snare. Not super strange by any means, but when you ponder the possibilities of using sidechain inputs to control something akin to sample playback in the analog world, it does open up lots of interesting possibilities.

About my metronome comment: here's how to use a compressor and an expander to build auto-pan, tremolo, and various other devices:

http://www.technicalaudio.com/pdf/Va...g_concepts.pdf

It's not trivial to set up auto-pan, but it sounds friggin' awesome. And you can feed whatever rhythm you want to control the pan rate, it doesn't have to be a metronome. It could be a sequenced pattern, a recorded track, a live signal, noise from an antenna, whatever.

The dbx 900 series compressors and gates have control voltage I/O for the sidechains. I'm just starting to get into modular synthesis, and I can't wait to start feeding sequenced CV patterns into the 903s to create weird throbbing effects. And of course, back to using the sidechain out: using the CV outs from the 903s will be a lot of fun -- take the synth for a compression drive, controlled by live dynamics rather than fixed patterns.
