I use a Machinedrum from Elektron (Sweden). It's great for electro or industrial. You can check it at machinedrum.com. I'm giving you hardware examples. Another possibility is an MPC 1000 or a used MPC 2000 from Akai (Japan). These two are my choices for drums and sequencing.
As far as cubase goes, you are going to want a drum soft synth or sampler to make the loops. It is possible to make them on the Indigo, but it would be easier to sample the indigo and use a dedicated unit to put it together into a drum sequence or loops. Look around and try some demo versions of software to see what you like. Use
