I use fl studio for most of the sequencing, i often use glovepie in conjunction with various controllers, but also use audacity sometimes. There may even be some loops in there i threw together in sonic foundry's acid style 1.0 long ago. I also use behringer's ucg102 and a vts plugin, Elottronix XL, which emulated robert frip's, tape loop machine.
Sure Ill see what I can do on the mp3s, anyone in particular you really want?
