I just purchased a Polaris.

Arrived with a broken key thanks to UPS, but I managed to swap it w/a
spare key from an Akai AX-73 (which needs about 6 more keys
replaced). In case anyone breaks any keys, the MX-73 also used the
same keyboard and I have a hunch that the X7000 sampler would work
too.

Aside from that my Polaris is in immaculate condition and it came
w/the origional owners manual.

I'm just getting into it, but would love a service manual and/or
factory patches. I would trade a xerox copy of the owners manual
for either.

Thanks,
Ben
