it's not too hard really .. once you have your mic setup basically choose a track (say track 1)
and click the R button there should be red ... next to the green mute button and the s solo button .. then you just press record and your away ....
if you want to use one of the many backing tracks you seem to have just go into the insert menu and click "Insert wav from file " then you can choose any mp3/wav/anything you like and slot it in ..
you can also download drum beats from www.loopology.com
if you want to make your own ...
if your having problems getting your mic to work .. it's prolly the way you have your control panels setup wrong for your mic not teh program
hope that helps !
