For this recording I only used a few components - I have a Korg Sampling Grand that I use for a controller.  That is connected to a TR Rack - basically the Korg Trinity sounds (the keyboard that the Triton is based on).  Sounds are very high quality and you can get good eBay deals on this unit.  I have a Behringer board connected to a DA-38 recording unit.  After I complete the song, I mix down to Cakewalk on my laptop.
