Syncing the mpc 1000 to cubase 4 with lexicon lamda

Can someone plz help me figure out how to sync the mpc1000 to cubase le 4 using the lexicon lamda?? What I want is to be able to track out at least 2 tracks at a time from the mpc 1000 into my DAW but i cant figure out how to setup the synchronization settings right. I have everything connected right i think but the option to select my audio interface in the midi clock destination field is not listed. I hope you understand the question im asking, this has become really frustrating for me.

First, have you initialized Cubase with your soundcard yet? You won't get much, if anything at all if this isn't done.
