I thought to write it myself: someone might find it useful.

So we all know rhe microSTATION and the M50/M3 share the same lineage,
but how do the micro's 49Mb EDSi ROM really fare against
M50/M3's 256Mb EDS one?
Pretty well I'd say, but the difference is quite noticeable in many samples,
where micro lacks detail and definiton (anyway I think all of micro's samples
are still both usable and enjoyanle, especially after some tweaking).
I found the main differences in acoustic pianos, acoustic guitars, saxes,
and flute (excellent on the M50, weakest sound of micro's)., just to name
a few.
That said, I also think that preset programming on microSTATION is
much better than in M50. Better effects and real time knobs,
more interesting and, in general "spacey", where most of M50 presets
sound a bit dull to me; e.g. I totally love micro's Reed Organ and Legato
String programs. Of course this is hardly a problem with a korg workstation,
simce you're supposed to make your owm sounds, but still the difference,
to me, is interesting. Did Korg programmers get better with EDS in time?
Or maybe put more effort in micro's programming expecting most of its
users not to want and edit their sound deeply?
Anyway, hope this helps... I'll try and record an mp3 with specific sounds
comparisons later and poat the link here... so... if someone wants me to
try something specific do tell me
