Recreating Microhouse "Clicks"

[Voyager77]

I really enjoy the sounds in this video:

I was wondering how I could create the shifting, percussive scrapes, pops and clicks in this track. They sound very similar to sounds I've heard in microhouse classics like Vocalcity by Luomo. I love the organic vibe..the scrapes in the very beginning before the beat drops sound almost reptillian.

I'd love to create these sounds using a Virus TI Desktop Module.

Also, could someone answer a total newbie question for me? I was wondering how you can trigger sounds live with a Virus TI Desktop without there being a keyboard. Do you need a MIDI controller or laptop or something to do this?
