Hi Steve,

I've owned a few Akai samplers back in the day and I don't think it's possible for an Apple product to read Akai data in any sort of usable way. Akai was Motorolla/ PC I think but never the less, pretty sure you are out of luck.

Akai finally added external storage ports to some of their samplers so you could use scsi zip drives but still not helpful for what you are needing.

Being said, I could wrong so let's hope someone else chimes in with a solution.
