To be honest I use only one EQ for each channel almost everytime, I have the idea not to process the bass that much. For me if a sound needs that much processing I'll just change the synth sound (I'm working just with midi so that suits me perfectly). By the way, I found some creative ideas using vocal effects vst's on the bass sounds (mostly AVOX vst's), give this a go! :)
Yeah thats cool, i still mix like i do with my bands and stuff but was able to transfer sort of the same techniques to dance music. Alot of my stuff is midi as well, but getting massive bass sounds has alot to do with compression, and my EQ'ing dosent look like the rocky mountains haha its more finer cuts and boosts. i agree if you need to over process something then change it. Yeah i've seen a few producers do that vox fx, still hasnt sold it for me yet
