Ok, that's a start. What type of sounds are you after ? Analog / synth types only, or emulations of other instruments, and if so, just keyboard based instruments or a general palette of sounds ? What exactly are you looking to do and what kind of music are you looking to play or produce ?

Really, it's a little difficult to answer without some further knowldege of what you want to do. We could probably be more helpful to you if we had a better idea of what it is that you are after.
