I have a set of Joey DeFrancesco EPS16+ sampler disks someplace that are very
sweet. These samplers maxed out at IIRC 2Mb RAM.

That's why it's as important to spec what a patch should do before one starts
as it is to spec a piece of software.
The physical aspects of the instrument one is producing need to be accounted
for. Am "I" trying to reproduce certain idiosyncracies (features) of a source
or eliminate them (bugs)?
Do I want the pedal thuds in my piano?
Do I want the motor noise in my leslie?
IMO the "right" way to do things is to break down the instrument one is trying
to reproduce and then use the available synth architecture to reproduce as
many of the dynamic qualities of a timbre as possible. The samples themselves
should be as close to a static nature as possible, i.e. the tone wheels of a
hammond always output the same waveform. It's the drawbars that dictate the
waveform that gets sent to the output and there is an infinite combination of
positions, so trying to sample every possible combination is brain dead.
If one just records a particular hammond & leslie sound and stuffs it in one
layer of sampler, it won't be anything more than that one patch. If one
reproduces the tone generators and emulates the construction of the
instrument, and it's signal chain (should one be necessary for the sound)
then it's possible to approach the real deal.

Well, recorded music cannot sound like live music unless perhaps somebody
discovered the ideal of microphone technique. Consider that in this
particular case, the output transducer has both a dynamic shape and
