E-mu E-5000 Ultra, plus SCSI CD ROM drive, plus some extra RAM. Hang on I already did!
Comes with loads of CD-ROMs with it so it can be every soundmodule in your studio for a long time. I can't remember what manufacturers jargon they give it, but it's so easy to patch any controller to any modulator (much easier than the Akai). The timestretch and pitch altering functions are easy to use. It sounds great (wicked filters). I can't compare it to the Yamaha samplers but personally I find it much, much better than the Akai.
