It's crazy, that nobody wrote review before me for this plugin.
I downloaded demo version weeks ago and played with it few hours. It never crashed or freezed my DAW. Zip file includes .dll file which you can easily export in folder you want (with VST plugins), but there's no manual for KickR. In my opinion you don't really need it and there are also 2 videos in Guda website if you want to learn how to use it.
KickR is fun to play with. GUI looks simple and clean, but don't be fooled with just few knobs (some "extra" knobs you get when you choose "Extended Body Section" - default is "Classic"), this plugin is hot! Really hot! And you have all you need to make good kick drum. It is one of the most powerful VST for creating/editing kick drums. In few minutes you get (original) kick drum sound that fits perfectly to your track. I also tried to create some other sounds like snares, hats and other percussions... but... well... it's best suited for kicks.
You can use your samples and import them in this plugin easily to change character of your sound. Knobs also have mousewheel support, so you can easily tweak your sound without annoying mouse clicks. I'm just missing function to type value you want for each knob. You can also choose different color schema, 3D look and few other things.
CPU usage is really low, in my older notebook it's about 0-1% (Win8, 32-bit, 2Ghz). Price is great too, only 19$/19€.
This is good choice for anyone who wants to get great kick drum sound with just few clicks and it's done in minute.
