Thanks Loop!
The bass is still running from the VST Sylenth. Although I think the main thing I use on all my bass, whether its Serum, Sylenth or whatever, is Waves Tans X. I swear by this plugin and I put it on 100% of bass tracks and it always, always sounds better. Of course the usual, get your filter envelopes sounding kinda snappy but I think you got that. Also I really like Fabfilter Saturn, add like 3-4 bands and play around with it. Qaudrafuzz is also pretty cool.
I do intend to bounce the bass to a wave file for when I make the final mix. Also think it could have a few more touches etc and make it a bit longer. When I'm done I'll post it.
Oh PRO TIP I saw recently: a lot of the groove and feel of the bass has to do with the first bass note. Make a separate track just for that first bass note so you can easily control it whenever you want.
