Sidechain Quickest Way? Please inform

[samsome]

I'm using Reaper as the DAW,

so i don't know if you can help but i'm looking the quickest way to sidechain,

i tried several methods but all take a bit more than it should

Curious what you mean with "sidechain"...But i guess, you just want the pumping fx.

Try this:

Devices have a parallel output without any of the insert fx applied which you can use as a sidechain source. Mix channels have a side chain input which I assume would work but I've never used it because there is no control over adsr that way. So I use the parallel out of the kick or whatever as the side chain source and add an MClass Compressor as an insert effect on the device to side chain. If you put the ratio really high, threshold pretty low, attack pretty fast and a long release you will really hear a side chain effect.

Pump is remarkably good at achieving the classic pumping thing with almost zero effort.

I don't know how you would achieve "proper" sidechaining with the Reason VST in a Reaper host.

The thing is reaper has scripts to do Sidechain in 1 second

in Reason the fastest way is to put things close
so that the cable is not to long. but is more fun

In every daw you put the compress on the instrument then route the mixer channel of a kick or something to the instrument with the comp in it.
You are chaining the kick to a compressor on the synth to make it pump.

Drop a Synchronus on your track and select one of the sidechain style presets from the factory bank.
