Sidechaining compressors for vocals

[rose]

Could someone shed some light on the routing for setting up sidechaining for a compressor(for vocals) in the digital domain.
My aim is to reduce the dynamic range without all the usual side effects of standard techniques.
I can do this in analogue, I need help setting it up using a digital domain, ie Ptools and a software compressor.

Thankyou.

Are you going to sidechain the vocal to itself or to another instrument? Sounds like your trying to chain it to itself... in that case you need to mult the track and nudge it back a few ms. Put the compressor on the original vocal track and sidechain it to the newly created vocal track. Then just adjust accordingly.

Hope this is what you are looking for.
