I use Native Instruments Kontakt as my main sampled bass source, but as a former owner of a real MiniMoog I enjoy having a decent software version of the Moog MiniMoog for synth bass. If I had unlimited funds I would probably go for something like the Arturia MiniMoog. It was actually tested and approved by Robert Moog himself.

I recently came across a software MiniMoog that was in my price range: free. The MinimogueVA may not satisfy purists. If that is the case, I guess I’m not one. It sounds good to me.
This matter of finding software instruments and effects, free and otherwise, brings up another recommendation: KVRaudio. This is a web site sponsored by Muse Research which covers pretty much the entire world of software audio plugins. Among other things, they offer a searchable database of pretty much all available audio plugins, free and otherwise. You don’t have to own Receptor to access it. This site is a must if you are interested in software sound producing applications.
Today's song clip, "Dark Side of the Moon", shows an early attempt where I built a song around a bass line. At the time I wrote it I was unaware of the album by Pink Floyd with the same title.
Also in the sidebar you can see an aficionado working with MiniMogueVa.
