The 2000 has an output gain adjustment in the OS. It's really loud at +12. It's nice and punchy at +6. But I keep it at 0. Thats still loud, even with a pair of headphones. So use caution with those settings.
Some things you'll need to get used to, like having no folder directory on your storage devices. But you make partitions to use as folders. You also need to save files using 8 characters or less. Anything over will not read properly.
Your best storage option is an external SCSI device. Don't bother with Zip or Jaz drives. They're notorious for sudden failures. A CF drive is your best bet.
Keep in mind when transferring files with a computer, only the first partition can be seen. So keep your transfer disk with no partitions in order to prevent a bit of frustration.
The 2000 can't resample, so your 500 will be perfect for that. But you might want to use other samplers with different sound characteristics and effects, depending what you're looking for. I use an SP-404SX with my 2000. Both samplers make up for what the other don't have. I like the effects on the SP. I had the effects board for the 2000. But I ended up selling it. They were very bland compared to the SP.
The limitations of this machine are not so bad once you get used to it. Coming from the 500, you'll find more features, aside of the antiquated hardware. It's got character. The AD/DA converters are very warm compared to the 500/1000/2500 generation. That's the whole reason I'm still using it, aside of the rock solid MIDI timing and practically bug-free OS.
