smart.
Make sure to post the track to me also!
Okay, I managed to implement your idea into a track. I have a bassline split in low/sub and mid/hi and I sidechained both with the kick, by sending the kick signal to both bass-layers’ send-tracks (so both layers have their own compression). Though I’m still trying to wrap my head around how to tweak the buscompressor… how should I set the buscompressor? And why like that? My guess is a big attack and small release… I have the current compression based on eeter’s example, but put the threshold to -45 and used smaller attack and bigger release…
Also, I noticed the GHOST instrument in the percussion, is there a reason it’s there? Should I put a GHOST on my kick’s channel to go along the compression?
Will put up the xrns-file once I’m satisfied with the result. But seriously, the brilliance of this sidechain method IS the simplicity 
Once you get how it works, it’s pretty simple and not that much of a hassle to set up. Yes, you get a lot of send-tracks, but hey… fukkit… It’s SIDECHAIN right? It’s what some Renoisers would sell their nutsack for!
Eeter, thanks a million for this great idea! It’s fun and exciting to experiment with this setup!
Cool… 
multiband sidechaining. I haven’t had the chance to test this by myself but I had the idea.
But I still think that using the same compression parameters as me as no point… There must be some more and scientific information about it. I am quite dumb about benefitial compressor usage. Sorry 
The ghost instrument is not used for compression. It’s just for triggering the LFO to create the one-sample-percussion. Not actually neccessary for this example…
I based my compression on yours because I thought it was ‘part of the sidechaining
process’ so to speak, but after some experimenting I found out it isn’t. It’s interesting that the lower
the volume of the channel you send through the sidechaining, the more obvious the sidechain-effect is.
I love how you have complete control over the process of the sound this way! Muting the kicks after
the sidechain-sends and exagerating the effect on strings are awesome! These are my first experiments
with sidechaining, so excuse my enthousiasm
I’ll post the track once its done 
File is done. Looking for a way to share it, so spam coming soon.
Bloody hell this is an excellent idea! Massive props.
Here’s a very simple demo I made to test it out for myself:

how bout a sidechaining compressor … and a key input gater as well
GUYS? HUH? Huh
so i don’t have to keep shuffling back and forth between pro tools for this effects …
help a brotha out!!! RENOISE 
This is damn sweet, got it on my playlist atm 
Too complicated, and doesn’t sound good. Maybe I’m doing something wrong. But love you for trying 
You probably are doing something wrong. Post your xrns and when I have the time I can take a look if you want.
I actually don’t think it’s too complicated once you get your head around what all the send tracks are doing. It took a while to set it up myself the first time, but I can now set it up fairly quickly and I was amazed just how good it sounds.
holy horse! 
great tune and perfect example for how good the native sidechain can sound with a proper sound design involved.
too bad the sendchannel frenzy kills multithreading efficiency - but nevertheless… if this ain’t predestined as a demosong i don’t know.
it’s musically original, lush sounding (!) and perfectly showcases a feature which was said to be undoable natively.
it’s also a good shocker for noobs as it rather looks like rocket-science than anything else
thanks for sharing, vivace!
kudos also to eeter for fiddling about that mind-twisting stuff!
Holy shite sir…!! Massive thanks for the props!!
… Can’t say I’d mind if this track was added as a demo-song, but considering the ‘workaround’ is relatively complex and somewhat ‘unofficial’, not to mention (hopefully) obsolete in the (near?) future…
came up with a way to use the Gate dsp a while ago to do a similar thing. thought i’d share it (if you don’t know how to do this already):
okay I’ve just discovered Sidechain Compression and it’s unfuckinbelievable how it can turn a rather flat mix into something really badass. (yes I’m a complete noob I know )
Now I’ll have to try to understand how you guys did it with native DSP only - or cross many fingers to find it in renoise’s next version … 
EDIT : now I understand how the trick works, but I can’t reproduce the sound I have with an external DSP. I guess it comes from the subtle tweaks of the compressor …
I do double duty on Ableton and Renoise these days, and even in Ableton with sidechaining natively available, i still actually prefer the oneshot LFO+gainer/filter approach in Renoise because of the control it gives you. For most purposes, manually ducking the signal is the more flexible, stable and preferable solution.
Cool technique, but i would never bother with it for the sake of a single channel’s worth of sidechaining when a manually tweaked duck will do the same thing and for all intents and purposes, better.
can you elaborate on “oneshot FLO + gainer/filter” ? Is it a LFO triggered by the kick altering the filter/gainer on the other track ?
