Compression question...

[nutrinoland]

Hi..
I just came across a problem while mixing a track and thought I would ask here..
I found that on a bassline that has a descending pattern as the chord changes, the bass loses energy and gains energy in certain parts...also the EQ settings for one section/chord section are not that suitable as the bassline moves to other notes in the next section...
I thought that the compressor on the channel placed before the EQ, would solve this issue by making the volume somewhat constant, and control the dynamics as the bass loses and gains energy in the different parts...
I cant seem to get it right...although when I listen to tracks where this is happening..the bass energy seems to remain almost constant...no matter what notes are playing..

DO I set up a different channel with seperate EQ's for each bass section , with appropriate settings ?? or is the compressor supposed to do a better job at leveling out the energy on all sections...

the bass notes for example are...C-G (a 4th below) then moves down to B-F then moves down to A-E ...


Thanks...
