Well.. I have one and I really like it.
It's not a do everything kind of synth, and you shouldn't expect it to.
Sometimes it's a bit too bright, it's hard to program multivoice patches, unless you mod it it's got a single mono out...functionally. no knobs for tweak..
But, I've always thought it sounded like pure sex with the right amount of delay and verb..
I wish I had some solo audio examples of it, but I really don't.. it is peppered all pretty much every song I've recorded though.
actually, here's a ok example.
the first voice you hear in this song.. the long env filter tone that's stepping octaves.. starting low and stepping through most of the keyrange.. that's the akai.
Is it worth being "rare" .. probably not.
