beat tracking with cubase

So i have a I have a eurorack ub502 mixer , rokit 5 monitors, lexicon omega soundcard and a mpc 1000 and cubase le. I have my mpc main outs to a channel on my mixer, my mixers TAPE OUT to my soundcard input.
my soundcard output to my mixers TAPE IN.

I cant figure it out, i am ridiculously frustrated. No matter what i do to try and track my beats into cubase, i get no response in cubase. i tried everything. I even tried pluggin my mpc right into the soundcard. I messed around with wires goin all ove rthe place and i still get no response in cubase, i'm ready to just throw my gear out the window im so mad, any help is appriciated thanks.

Sparq made a "track and sync" video and he also uses the lexicon omega. he's tracking into Nuendo, but it's the same user interface as Cubase.
Download the vid below and you'll be trackin your beats in a minute.

this may seem obvious, but have you clicked on the monitor and record buttons on the tracks you are workin on?

A lot of the Sparq videos are on YouTube.com

A lot easier than using Megaupload...

It's easy once you know how. I watched the vid and it wasn't exactly the same as he uses Nuendo and i'm on Cubase but it's very similar.

Watch the vid, follow all the steps and if you're still stuck, drop me a PM.

Are you syncing the MPC to the computer with midi?

do u have ur cubase prefs set up so it recieves audio in thru the right thing. for example the factory settings in cubase could be for the audio to come in thru the audio in minijack built into ur computer but if ure using a usb or firewire soundcard u gotta specify in the cubase preferences to use that for audio in/out. but ima mac person maybe this is different on pc's
