Alesis says in Os 2.0 they're supposed to add many more features i.e. Compact Flash Type I and Type II (Flash and Microdrives), SATA HD and (by Winter 2005/2006) CD-RW capabilities.
I emailed Alesis about when Os 2.0 was droppin they had no clue.
Oh if you ever want to add more ram in it, good luck. It uses some weird proprietary memory called "E2/E3 Sdram”, and has to be bought in sticks of 2. 128mb each.
Alesis had informed me in an email no matter who installs the memory, Alesis tech, authorised dealers or yourself. While the machine is open it’s not under warranty by them. That’s my main reason for returning the machine, and the sampler sucked.
Other than that the machine is really good.
