I was well impressed with Translator when I reviewed it for the
accuracy and scope of its conversions, but like all translation utilities it can never be
100% perfect - different libraries use differing amounts of the 'special features' that
some samplers offer.
If the EOS library you're intending to convert is like a
lot of others in mapping samples but not using engine features like LFOs, filters,
envelopes, and the like then most converters will do a fairly good job, although I've
often found the dynamics to feel slightly different afterwards.
If on the
other hand it does use these features then you'll probably find the LFO speed and depth
significantly different, filter sweeps totally different, and envelopes altered. As they
say, your mileage may vary.
