Of all who replied so far, I think I may have the skinnyest toolset of all.
1. BiaB
2. Studio One (ver 5)
And although not software tools
3. My Fender Bass Guitar
4. My Korg Keyboard
I'm considering a VST or 2 but (right now anyway) I consider any tool that takes my fingers away from my physical instruments a musical net loss, with the exception of BiaB.
To be sure, I'm not certain I even know what a VST is, and there is much for me to learn but from what I've seen so far, for me, pressing a physical key or fretting a physical string is more gratifying that moving rectangles around on a screen even if my final output is unpolished and down right rough around the edges
