ADD is a VST instrument, so you just "F11" it and load it up. Then add a midi track, and on the midi tracks output you route it to Addictice Drums. Double click the midi track to open up the map and draw in your notes as you wish ?

Do most of the processing on the plugin and at the bottom of the fader track is an arrow pointing down. Clicking that will allow you to edit the individual tracks on the program, in Cubase track if you wish.

For easier midi drawing just hold Alt which brings up the pencil tool once held. It saves time from click on the pencil button and then drawing and then the cursor button to edit.

Where must i click on the midi track? I`ve opened the add in the vst box and routed the output of the midi track to the add, but i`m double clicking on the midi track and nothing??

I got if figd out, just a last question - how do i put triplets in?

You put the quantisize (or however you zpell that) to 1/4 or 1/8 or 1/16 triplets and then program or record the stuff. The quanti..eh..thing pulldown is on the top bar of the drum editor window.

Yeah it's cool in the MIDI because the grid adjusts accordingly but in the edit window the grid stays the same.
