AJ,

please explain difference between:
software upgrade & hardware upgrade?

how can there be just software upgrade? i'd think they work together in a way...
i would think the software (new styles & stuff), requires NEW sounds that could only fit with hardware modification (increased memory)

also , prices for software only? hardware FULL etc.?

question, is there a Hardware upgrade ONLY? meaning just increase in memory without new styles, etc?

thanks again...
