Just curious.

depends on what you're trying to make

what I have installed atm== iZotope, ReFX Nexus2, Omnisphere 2, vintage drum elements, drum PRO

I dont like using vsts too much tho cause they make FL crash and I cant afford to risk it.

If I want a certain sound on my drums I use layers on top of layers and as far as melodies go I sample and arrange my samples in very weird ways but somehow it works for me.
