Hello paw1,
I think the easiest thing to do will be the following:
Go to Devices > VST Instruments.
On the VST Instrument Rack load
Addictive Drums on the first available rack.
A message will prompt asking if you would like to create a MIDI track, click on create.
Now your new MIDI track will be routed automatically to the AD plug-in.
The thing is that the MIDI track is empty therefore you will either need to write down the MIDI manually using the draw tool, or you can use the beat designer tool.
To access the beat designer go to:
MIDI Inserts > Beat designer.
Here you will see a small map of almost all the available sounds, or if not at least the most common ones (Bass drum, snare, Hi-Hat, etc...)
Draw some hits on the available spaces, and you should be able to create an easy beat in a couple of seconds.
Once you have one that you like and want to import it into the project, click on
the arrow at the top left corner of the Beat Designer window and select: "Insert Pattern at cursor".
There are many other options I am just mentioning the first one available.
I hope this helps you get your self started.
Best regards,
GN
