Nice article, but now I'm confused... I've never really done much with the "key function" but it sounded like a neat feature. To get a better understanding of how this would work I looked in the manual, but it doesn't really tell much. So hear are my questions...

When would I use this?
Why would I use this?
How would I use this?

When would I use this?

Every time you use the dynamics section in Final Mix

Why would I use this?

Because thats how it works :P

How would I use this?

Big question! The "key function" is part of the cross-over, and is the main difference between the Final Mix dynamics section and the Mackie 3-band Compressor:

In the 3-band comp you get to specify two cross-over frequencies and their steepness. The compressors monitor the same signal in the side-chain as they pass through the signal path.

In Final Mix however, you have extra options: the audio path is split with conventional crossovers as in the 3-band comp, but you also get 3 powerful band-pass filters which control the signal feeding the side-chain. This allows various intersting things to be acheived, eg: the low cross-over could be set to 200Hz, while the low compressor side-chain filter is set to home in on the 90-200Hz range (which could reduce pumping caused by very low kick frequencies)

Pressing the "Key solo" button allows you to hear the side-chain for that band to make zeroing in on particular instruments easier (it also allows for cool filter sweeps btw!)

Possibly the simplest way to use this knowledge is to adjust the volume level of the side-chain filter.. this can provide a simple way to adjust the overall threshold of the dynamics, which can be useful when several nodes are in use to make complex transfers. (Turning the side-chain level up is the same as turning the threshold down & vice versa)

Thanks there IIRs... I kind of suspected that that would be the response for the 1st two, but your explanation for the 3rd helps much... Usually I would just sit on the dynamics graph and just start moving things around until I got a sound I liked. Maybe now I can think thngs through a little more.
