ok, the bass station is actually pretty dope in my opinion. here is my take on its strengths and weaknesses:
weaknesses - leads. you don't want to do leads on a bass station. you really don't want to do anything with the bass station that has to do with the mid to higher frequencies.
strengths - bass, filtered down. some people like to have their basses contain some of the overtones, but on a bass station it doesn't sound that great. however, work in the low frequencies, let the filter cut down the wave to a low enough frequency and boost the resonance, and you get a reeeeally fat sound. that is the sweet spot, that is where the synth really sings to you.
just look at the bass sounds that these producers use it for: the rza (wu tang), radiohead, massive attack, salaam remi (new nas album), havoc (mobb deep). in the cases of radiohead and massive attack and salaam remi, they use many other bass sounds, but you can pick out where they are using the bass station if you are familiar with its sound. anyways, with those producers, those are some fat bass sounds.
if you want to hear the bass station's sweet spot that i am talking about, check the link in my signature that takes you to my soundclick page (click the "music" link on that page), listen to "could die" and "col. mustard", which i used the bass station on. "col. mustard" actually doesnt use a straight up bass station but rather the playing of a bass station sample that i recorded from my bass station into my eps-16+ sampler. unfortunately i haven't posted the majority of my tracks that use the bass station (most of my tracks do), all the other tracks on that soundclick page use bass from the cheesy reason subtractor (im goin to have to go back and replace that with some bass station).
