This vsti gets the heaviest use of any of my plugins. I'll quickly list some pros and cons.
Pros very stable fast and easy to use several different types of samplers available lots of synth modules does everything a drum machine should be able to do easy file browsing supports drag'n'drop supports mfx such as slicydrummer and fillindrummer supports use with phatmatik pro lots of sampler cells good documention
Cons I'm not sure I would call anything a "con"
There are a few features that I would like to see added (hide unused cells, amp envelope), but I believe things like this will be added in the next release.
I demo'd Battery, and found dr-008 to be far superior. Tech support is excellent. There is a large library of kits available to users. This product is winner.
