Possible to transfer beat in multitracks from MPC1000 to....

my computer via the CF card? You know, the kick on one track, the snare og one track, the hat on one track and so on... Or do I have to make connections to my soundcard and record it manually, four tracks at a time (through the four assignable outs on the MPC1k)?

Yep

Hit Mode -> Record

Chose Main Out as Input

Hit Record (F6)

And then you can save the sample you just recorded to a CF Card...

Assign pads to multi-outs on 1k. Use computer multi-input interface to record separate tracks in your fave multitrack software.
