Ampfixer! You have to click on settings and that takes you to the drum map setup. Everything is blank. Click on default and it should load a GM drum map. Next you have to go back to the drum view and click on mixer. All the levels, pan, compressors, etc., have to be adjusted on the mixer to hear audio. Once you have the setup you want to use it is best to save the settings so you can load it the next time you pull up the plugin. The plugin has to be setup everytime that you use it. It is totally blank at startup.
It kinda took a while to understand it but after wrangling around for a few minutes it was pretty easy to get something happening pretty quick. The secret is in the presets for you to load to setup the kit.
I did pull the grooves over in a midi track in Sonar and they went right in. Other than the setup being a little difficult, this plug would make a good first timers drum rompler. It looks very much like EZ Drummer as far as the Groove Construction is concerned. At least it is a lot of fun after wrestling with Superior Drummer for hours! LOL!
