FWIW I find myself using Fretted Synth stuff quite often.
Freeamp Full and Helian Bass make things quick and easy .. but have a lot of granularity available

They are older, but also pretty intuitive and easy to get up and running.

Note that all versions of freeamp were different. Some seem to play nicer on a given system than others .. trade off for the cost I guess.
I've only tinkered with the Freeamp and Helian Bass tools .. there's a lot more on this page.

I do not work here, but the benefits are still awesome
