Using EQ's to activate sidechains

Is it possible to have an EQ that isn't effecting the sound but however is used by a sidechain to make the sidechain's activation more selective?

Example: You have channel playing a track, and have an EQ on that channel that isn't effecting the sound. The EQ is used to make the activation of a sidechained gate on channel 2 more selective (the gate only triggers when the eq'ed frequency hits above the threshold, however the full frequency is still playing).

Thanks.

erm...not really sure I understand

but the compressor's sidechain has an EQ that you can set so that it only responds to certain frequencies - you could probably rig something up, just set the ratio to 1:1

yes the sidechain eq is part of the Ableton compressor ??

Ok I could have explained myself better.

What I want is:
Track 2 playing. I want to sidechain a gate for track one so that when the mid frequencies of track two go above the threshold of the gate, it opens.

So I want the gate to ignore the low and high frequencies of track 2, and only use the mid frequencies of track 2 to activate the gate.

put the compressor on track 1 in sidechain mode an enable the EQ and you should be able to work out a way - if you press the headphones then it plays what the sidechain is responding to

Yep thanks, that works like a charm. it would be really cool if the gate had a built in eq like that as well too hey.

Glad you got COmpressor to work for you.

If you wanted to use a second audio source as the sidechain input, you just drop an EQ on that track. You wont hear it because you'll need to route that track to the COmpressor's side input anyway.

Now, if you want to hear track B, un-EQ'ed, just copy and paste it. Or create a return track and turn up the Send (and hit "Pre" not post fader)

Still, it'd be nice if we could do this all inside a rack, and have one chain output the dry audio and the other chain routed to the side-chain input of a compressor somewhere.
