Lamp's right. If you're just getting into production and have no experience with the old hardware MPCs, you're gonna need a lot of time and patience to get the results you're looking for.
With the 2000xl, you're gonna need the 8 output board installed in order to multitrack record into your DAW. So you'll need the 8 output board, a recording snake (which is 8 cables in a bundle), and an audio interface with 8 inputs. So you'll have to spend a lot of money to buy all that stuff. Not only that, but you'll need to deal with legacy storage options on the 2000xl. Whether the machine has a floppy drive, zip drive, or a CF drive, you're bound to deal with more issues. Then theres other things that can go wrong, whether you have to replace pads, sensors, tact switches, display screens, etc.
All these things are bound to need replacing, costing you more time, money, and patience to maintain.
With the MPC Studio, all you need is a small 2 channel audio interface. You'll have better integration with the MPC software and your DAW without the need for additional cables, etc. All your samples will be stored on your computer. No need to deal with transferring samples back and forth from the computer and the MPC.
Take the path of least resistance since you're already working with a DAW. You'll get more work done and have less issues to deal with by choosing the MPC Studio.
