Standing on the throats of giants

So I've been spending a lot of my free time at home listening to the gems at Nine Inch Nails' remix site. Why? Well aside from the fact that there is some really amazing stuff there (occasionally the remixes are better than the original), I've been playing around with the idea of remixing the song Survivalism and so I've been looking for inspiration.

I have a working title and I've started cutting up the vocals from the multi-track files for the song, which are available from the remix site but also from the DVD that comes with Y34RZ3R0R3M1X3D (yes I just typed that out). My plan will probably require that I create some of my own vocals as well as some keyboard work, so I'm in the market for either a MIDI/USB interface or an inexpensive USB MIDI controller. Given my space constraints in my little corner of the world, the controller would be easier to work with but the interface would likely be a lot cheaper as I already have a fairly nice keyboard with MIDI ports. It doesn't have a pitch binder, but I can do that in software after laying down the track.

For now I'm still in the planning stages. Listening to the samples over and again, as well as to others versions of the song to see what works well and what doesn't. I haven't done anything like this since back in the heyday of MOD and S3M tracking and my experience with GarageBand is just a few steps short of none... this should be interesting and I hope in the end turn out well enough to post back to the remix site.
