Probably the best place to start with the 'pulve' is to look at the pre-sets. To find these right click on the pulve where there are no knobs or switches, a play symbol will appear, click on that and some pre-set options appear. Take a look at the 'init' pre-set first, click it and the pulve will automatically set to that. Open up a note track and set some notes and make a loop. Play around with the different knobs on the pulve, also plug some fx in, a delay or reverb, or both, and just experiment!
Oh and there are tutorials on youtube as well if ya wanna check'em!
Hope this helps a bit! Keep with it m8! :)
