Reaper here, with mainly 2 plugins :
- Ample Sound Bass P Lite II : really great because it's free, the sound is great and it offer the ability to import Guitar Pro Tab -> no MIDI programming (it handles all bass articulations according to the Tab)
- EzDrummer : quite not so expensive (i've seen that slate gives a free light version of SSD5 -> probably a good free alternative)
Ready to go !
