hey everyone! inspired by jordi's method of side-chain, i tried to make it more streamlined.


essentially all i did was allow the sidechain to be controlled by an audio trigger, so that i, in an astonishing feat of laziness, don't have to automate the compression curve! i did this by

- splitting the aux send

- flipping the phase of one

- merging the two

- putting a gravity (with bd sidechain) on the un-phaseflipped (there's gotta be a technical term for this right?) signal

- mixed back with main mix (via aux return)

at this point, it acts as a normal side-chain would, but you have much more control over what instruments are getting compressed, and how much. you can even use prefader to create a reverse sidechain effect! i'm definitely going to be using this technique in the future! total sidechain control with only 5 devices!

in essence, it's an XOR gate and two AND gates—a realization that makes me want to experiment with logic gates using audio. what if... we made a turing machine??


everything jordi wrote still applies to my version:

Here's an efficient method to implement varying degrees of side-chain compression for multiple tracks using only one Panorama device:


• All the tracks except drums are sent to an Aux Send on the Centroid. Each track has its own Send value.

• The Aux signal is phase inverted with the Panorama device.

• The inverted signal is fed back into the main mix via the mixer's Aux Return.

• Since the return signal is phase inverted, it cancels the original signal and lowers its volume.

• By automating the main Aux Send knob you can create a volume pumping effect. The curvature of the automation segment defines the envelope of the pump.

• You can control the amount of pumping for each individual track by varying its corresponding Aux Send amount.

Open the track, solo each Centroid channel and vary its Aux Send amount to change the amount of side-chain compression effect. Open the green automation region and change the curvature of the segment to change the envelope of the effect.

  • Hey, thanks for the comment. Yes, it's interesting. I'm not sure why you need to split the signal though. If you want to vary the amount of signal reaching the panorama without using automation, you could just use the compressor or even a gate triggered by their side-chain input. The idea was to get the effect of side chain compression on a whole mix with per-track control in a very simple way without using a compressor.

    • This technique is unprofessional but very effective

      Turn on limiter

      split the kick channel and turn up the volume and bass

    • since no effect in AT has a positive response to a sidechain [sidechain volume goes up --> effect volume goes up] the splitting and merging is the only way i could think to imitate that.

      (+) control signal --> comp. --> (-) in-phase signal --> merge --> (+) out-of-phase signal --> to centroid --> (-) main mix.

      EDIT: after writing this i remembered that the gate has a positive response setting. i suppose that's what you're referring to! silly me that's a much easier solution :) cheers!

    • great to hear from you! i feel that your solution has a charm in its simplicity that mine lacks. splitting the signal seemed to be necessary for this to work the way i'd hoped. if you were to place a compressor or gate—sidechained by the control signal—before (or after) the panorama, and then route that back into the centroid, you'd get the reverse effect (demonstrated at 0:31 ).

      control signal increase --> compressor --> negative phase signal decrease --> main mix amplitude increase.

  • Yes I understand how this works....

    *inner panic because I dont even know what half the switches on the pulv do and thats the only thing i understand anyway*

  • Brilliant!
