Greetings!

As a beginner, I am willing to create a soft and organic kind of VST bass sound that's why I am looking for bass guitar VST plugin in this regard. If we talk about the free plugins then I like Tal Bassline because of its simple keyboard synth but its free software has fewer features as compared the paid one. That's why I am looking for any other free plugin which offers all features with the free version. 

On the other hand, I found both paid and free bass guitar VST plugins from here and I think Kontakt Bass Gravity Pack is the best among all paid options because of its features of composing outstanding bass effects. However, it is very expensive with price tag of $99. All in all, I am confused and want a free plugin as a beginner. 

Withal, if you think I should try a paid version then keep in mind, I can't afford more than $50. Please give me your best suggestions. It would be great if you share links of these free VST plugins here as well.
