On the other
hand, the KARMA software is available for the Korg M50
too (and the Triton:
http://www.karma-lab.com/ ) but it needs Windows
or a Mac; and the price of a new M50-61 and KARMA is a good $400 less
than the M3-M.
In fact, perhaps the cheapest way to get hold of KARMA technology is
KARMA for Triton and a secondhand Triton LE - shouldn't be much more
than $500 overall. (Might be worth asking whether it would work with
the PA-50 too, but I wouldn't necessarily hold out much hope.)
Though for that kind of money you can get quite a nice guitar and
lessons. If you really want nice guitar you can always ask one of the
wonderful guitarist here on LAU to record it for you. :) In turn you
might be able to do keyboard / piano parts for there tracks...
