sorry 4 the long post
if u use Logic Audio its easy as a kid game, u use the proper sidechain function of the compresors, they have build up internaly.. if not, here u have 2 solutions:
try the TC native bundle, there u can find among the other plugs an plug named "sidechainer". u put this plug on the kik channel (u must put it before the compresor) and than u put the compressor on the bass channel. when u open the compressor (the tc-compressor) u`ll see a button KEY ON. press it, now u're sidechaing, but to hear the real effect u need to play with the treshold, the release, the attack and all other functions
Try to lower the threshold to -19, try to put the ratio like 8:1 and than play with the rest, like Hold etc. to listen what u're doing u can mute your kik and u'll hear how everytime the kik plays it lowers the bass (even if the kik is muted..). This is the Raw way to do it. If u want better control u must make that the bass is compressed just by certain freqs of the kik (the ones that are in conflict with the bass). U do this so:
First send your kik to a bus (aux), but keep the output of the kik untouched. thus u have 2 kiks! so.. u mute the volume of the kik on the bus, u put an eq there, cut all the highs and all the lows (till 80hz) so u have isolated just a small freq-range of the kik (the punch, between 100 and 300-400hz), than on the same bus and after the EQ u put the Sidechainer of the tc-electronics. than u put the compressor on the bass channel and u folow the same as described above. u'll notice that if u begin to play with the equalizer (punching more the freqs, moving them a bit) u'll notice how this effects the bass, actually the bass is compressed via sidechain not from the whole kik but just from its punch, so the compression is much more faster and is not eating your second 16th of the bass line (supposing its a line of 16ths), so u must play a bit depending on the real sound of your kik and bass.
now if u want to use the Waves C1-sc (sc is for sidechain) u have to do it nother way:
as waves-c1 permit sidechainig over mono signal u have to make a lil trik. U pan full left your kik, and pan full right your bass. u send them both (panned) on a bus (keep this bus stereo). put over this bus the waves c1. and also send this bus to another (second) bus but this time make it Mono. So.. u openn the waves-c1, there u have to define that L (left, the kik) is compressing R (right, the bass). u have to play with the treshold, ratio, etc etc standart operations for comrepsors, until u get the desired sound, also in the C1 there is a very usefull function for internal equalization of the sidechain effect (thus u dont need to sedn the kik to another bus,make equalizations and stuff..).. everything u need is in the Waves-c1 compressor...
What u Must do if u DONT WANT TO USE THIS FUKING, BRAIN-CUTTING sidechain...???
imagine: a 4x4 standrt loop for trance should consist of 1 kik notes and 3bass notes.. like this: KBBB-KBBB-KBBB-KBBB.. right?
But the problem is that the kik, in most of the cases will still sounding when the 1st (2nd 16th) bass note is played.. so thus it interfers, and makes the sound horrible... U have to !!Shorten!! your kik! a lot of ppl think thay have to put all kind of warmers, bass-punchers, subbass boosters and other shit like this on the kik or on the bass and ths is an ERROR!!!! u put this shit when a mastering process is applyed! not earlier. U have to low-cut your kik (30-40hz) and also your bass (40-80Hz depends) so that there is ROOM! later.. when the trak is ready u can put warmifiers, bassboosters or whatever shit u like.. Why u make this? Because the subbas waves are extremly Potent and Powerfull but not so audible! so they will Mud your mix, they will interfiere over the entire frequancy range, and will mud everything and u'll finish pumpin up the volume of everything else.. and u'll destroy all the dinamics of the trak..
The subas is one of the biggest enemies when u make the trak. forget about them, u have to construct a good punchy and warm kik-bass and this u determine in the mid range, not the subbas raNGE.
What i meant is that u have to imagine this 4 "boxes" 1 for the kik and 3 for the bass notes. The idea is that the kik must not go out of its "box" because thus it interfear with the bass. But if u use sidechaining the kik can go out and can be heard even the 1st and 2nd note of the bass are played and both "fit" into one another because of the sidechain. Using a good constructed sidechain u can also have 4 16th bass notes!!!! every first note will overlaping the kik but if u have sidechain they will not interfere!! A MAgic
and also your bass will be more rolling!
..Or u can Equalize your bass (open certain freqs) so that when the kik overlaps it it fits into.. but for this u need really a very good equalizers and also a studio monitors, cuz on phones or other speakers the bass not heard correctly on the freqs we are speaking...
anyway... hope i've cleared (or blurred ehehehe ) more the sidechain situation
