Rikki,

The flash memory is only 373 kb in size, so you have to be very choosy as to what you load into it. I've added 11 songs and 5 styles and have room for a few more. I like the 403 a lot. At one time I had a Tyros and at another time I owned a psr3000. But for simple self-entertainment, I find this inexpensive keyboard very entertaining. No you can't mix and remix and there's no megavoices, but it's just a fun board for not thousands of $ but mere pocket change in comparison. That makes it even more amazing and worthwhile. Almost anyone can afford it.
