congrats. the MS2000 is a great sounding synth.

The best way to get the most out of it is to learn how to build patches from the ground up. play with the presets some to get a feel for what kind of sounds you can make, then pull up an -INIT- patch or some such and start tweaking.

First mess with the OSC settings.....then AMP envelope......then filter....then filter envelope....then some FX.....

There are plenty of good subtractive synth tutorials online as well, just do a google search. But the best way to really learn is to just spend time playing with it.
