I've never used an MPC4000 but I can offer you some general advise
on recording the MOTM.
First off, there is a big advantage to having 24 bit versus 16 bit.
Secondly the sample rate is not nearly as important as the quality
of the converters and most importantly the quality of the lowpass
filters.
Thirdly the importance of clock stability cannot be overstated.
Jitter can do some really weird stuff to your recording and you'll
pull your hair out trying to figure out what is causing it.
There is nothing wrong with recording at 44.1Khz or 48Khz if your
converters and filters are high quality. I use Apogee converters
almost exclusively. I almost always record at 44.1Khz, because my
stuff is intended for CD. There is no such thing as a perfect
sample rate conversion from 48KHz or even 96KHz or 192kHz to
44.1kHz. With the right converters and filters, and a stable clock
recording at 24 bit and 44.1Khz will certainly capture the nuances
of the MOTM. If you record at 24 bit and are going to convert to 16
bit be sure and add some good high quality dither as the last step.
I never have added any EQ to the MOTM when recording either.
Although I haven't tried using FIR filters, the typical IIR filter
will mess with the phase relationship between the harmonics and can
smear the sound. To me the MOTM sounds best recorded straight in,
with no compression or EQ, just a little attenuation.
