Yeah U can do it in fruity... don't even remember out 2 do it anymore but I think u can even find it in the help files!! But like IQ said it has Something 2 do with the peak controller.
SX ... U need a plug in that has the side chain option...
I know waves plug in has one (in fact C1 if I'm not mistaken)... u basically have 2 load a plug in called side chain to the Kick channel (or what ever u want 2 use to compress the Rides) and then on the ride channel use a C1 (on the C1 channel U have 2 activate Side Chain or key insert what ever "name" they use 4 it.... Mind u I've never donne this myself with the software I just know it's possible uppon reading they're help files)...
This topic has been fairly discussed b4 mates... Just look it up on the older posts...
PS - Adding 2 channels is not at all the same... cause u have 2 sounds together... But yes if u use the kick load enought in the mix it will compress the ride, still the result is all so different from sideC.
I used this method a lot 4 bass on my Yamaha 01v!
