presonus and FL have S/C done via a bus on the compressor or limiter and some great vst out that all allow S/C
or if you want you can use the peak controller in Fl to control a slider or gain ctrl
Sidechaining is one of the most important elements in modern electronic music, especially for progressive trance, electrohouse, etc..
Cubase versions >4.1 offer a sidechain function for different VST fxs liken compressors, gates etc..
But my favorite sc-vst is the Vengeance Producer Suite Multiband Sidechain. There you can chose between different sidechain sources, like an audio source or midi, or snyc to the sequenzer (which is usually more than enough). The second great thing about that sidechain plugin is the possibility to seperate sidechaining into a low and a high frequencies section. this makes it possible to hear the bass sound e.g. while the bassdrum ist playing, without taking the power of the bassdrum.
I used the plugin in my song 'eternal love' several times. You can listen to the song at http://internetdj.com/EarthShyT
i usually just use sidechain increment on beats from bass input and it always work for trance..there are many things to say about sidechaining, this is a thing more peoples should be aware..a lot of peoples always ask themselves why they don't have the "big sound" even with expensive vsti or synths, this is how you use it that make good or not...a cool article but there is a lot more to say...logic isn't a very common soft...all i can say is that there is gate and compressor sidechaining, 2 differents features, the magic is to find your own formula of sidechaining belong what you are doing, an entire small book could be written on the subject..if everybody tell how he does..yes
Do you still need to use compression for the entire track once you use side-chain compressors for your individual instrument tracks?
