HI
good luck for you
and if you get trouble and you cant record anything
you should go to Devices...->Device Setup. Under VST Multitrack, select your input device (the Alesis). Then make sure to go to Devices...->VST Inputs and enable whichever inputs you're going to use. Then on the mixer, pick a track and assign it to pull from one of the inputs you just enabled. You should be seeing the meters dance on Cubase now. Arm the track, press record, and off you go.
Looking forward to your success
cheers
