Put some stuff in there and start playing with wave parameters and looping modulation and the FX, and then wonder why your MPC sounds sterile in comparison. You don't need a lot of room for sounds. I'm first owner. My friend was jealous cuz he bought an EPS-16+ right before the ASR came out, and he was limited to 2megs, which was ridiculous compared to the units that'd gone before.
If you make 32khz mono samples, you can get a whole vocal track, loops and instruments in there without a problem.
try down converting those samples that make up that 12 meg guitar solo. you'll be amazed at how good the asr sounds with "supposedly" low resolution samples...and how much space it will save. But, that's just the ASR. I've had all of the Ensoniq samplers, and the ASR is the only one that was actually good with low res samples.
