Hi guys, I'm using a lot of compressors on the DAW and been using some very good compressors, mainly UAD and Vertigo VSC-2. Is it possible to sidechain (ducking from another track) this compressors somehow using logic? Do you know any other VST that has the sidechain feature such as the Logic compressor? By making a small research I found out SD-Comp 87 and db Audioware sidechain compressor.
See you |

Compressors with 2 stereo inputs (4 inputs):
Stillwell Bombardier
Compassion DMG
Crunchessor Voxengo
DensityMKII (haven't tried Density MKIII) .... and ThrillseekerLA.
Softube FET and Tube-Tech CL1B... and Valley People Dyna-mite....
DDMF NYCompressor
Elysia MPressor
PSP MasterComp and MixPressor2
Compressor by Slim Slow Slider
Sonalksis SV315mk2
TheGlue by Cytomic
TrackPlug 5 by Wave Arts
The above Fabfilter Pro-C and DC8C
Others....
db Audioware sidechain compressor is not a "real" sidechain compressor but it works very well, it has 1 stereo input (2 inputs) like Sidekick by Twisted Lemon. www.thepriest.site11.com - Freeware plugins |

Nice APriest, I'll try to research these plugins. By the way, yesterday I added some Vertigo VSC-2 instances on several group channel buses and removed the instance on the output (riding the fader), leaving just the limiter instance and got really nice results. No sidechain on this one but highly recommendable for limiting and, especially, riding tasks.
See you guys, thanks for the replies.

btw Audio Unit plugins got all sidechain inputs in logic for years^^

most comps that have external sidechain have that feature for routing .
dc8c is very good when the attack rlease behavior is suited as it s very clean but more in analog way it don't ruin the sound much with heavy compression but most recent comps are probably great (elysia mpressor plug for example it may be good for this ,dunno..) |

I should maybe start a new topic but since this is about sidechain compression i'l ask in here. Does anyone know of compressors that allow sidechain filtering? My knowledge of compressors is not the best… |

the side chain is the "control" signal of a compressor. an external side chain just means that you have access to this control signal, and can feed it anything you like. normally, some kind of a voltage envelope detector follows the peaks and valleys of an audio waveform fed to the compressor. this signal, adjusted by the compressor's manual controls, then affects the audio signal.
http://en.wikipedia.org/wiki/Dynamic_range_compression#Design
in the diagram above, the side chain is clearly labelled.
the interesting thing is when you have external access to this signal. imagine routing that side chain signal above, to another piece of gear, before it goes to the gain reduction circuit. i'll come back to this in a minute.
most people, when discussing "side chain compression" applied to dance or popular music, are talking about using one instrument to control the compression characteristics of another. the classic example being the kick drum affecting the level of the bass line in a mix, pulling it down slightly every time the kick drops, giving more space and "oomph" to the kick, whilst reducing clashing frequencies.
this is not a new trick. stock, aitken and waterman were using incredible amounts of linked/side chain compression on many tracks of a mix with a lot of their 80's pop productions, for that extra snappy and "in yer face" sound. think early kylie minogue, rick astley, bananarama, dead or alive, sigue sigue sputnik etc.
ok, so you understand what a side chain is, the fun part comes when you realise you can route it to ANYTHING! apart from the "classic" use, as discussed above, you could, for example:
1) leave the side chain alone, and route the audio signal to a delay, and you have "look ahead" compression, that starts compressing before the beat/audio.
2) or, route the side chain to a filter (like you suggest). many compressors with no external access to the side chain, still have a side chain knob or switch, which is 99% of the time routed to a high pass filter (sometimes with switchable positions). this allows you to set how much (or how little), the compressor reacts to bass frequencies. it's just the thing for acoustic strummed guitar, or whole mixes, where letting all the bass frequencies through to the detection circuit will be way too audible/pumping. a HPF in the side chain allows you to tune just how much "pump" you want from the bass. a LPF or BPF will have similar results on different parts of the audible frequency spectrum.
3) "creative" uses. e.g. feed the side chain to a flanger/ring mod/phaser/frequency shifter and just listen to what effect it has on the compression characteristic.
just remember that the side chain is not an audio signal, but a control signal (although you feed it with an audio signal), and it should be clear.
ANY compressor with an external side chain (plugin or hardware) will allow for these type of experiments. some have no external access, and some have just the filter (usually HP, but not always), sometimes with a fixed frequency, and sometimes with selectable (e.g. my chandler germanium compressors have no external side chain, but a HPF with the following positions: OUT, 30, 60, 90, 150 and 300 Hz).
hope that helped!

To get you started, the FabFilter Pro C compressor gives you HP and LP filters on the sidechain input and the Waves compressors (including the SSL emulations) pretty much all have versions that allow some control over the frequency content of the sidechain.
