Yep, ex-E-mu, now Apple.
For your question of how many channels, you could probably just get a master dump and check the number of channels.
For subs, I see where you're coming from, but I think you're misunderstanding how subs/sends work on the E-mu products. Essentially, there are 4 stereo busses to which each layer can chose to send (at full volume). Then, each of the busses has a percentage which goes to each effect. The only difference between the boxes with the extra six jacks is that they can interrupt the signal from the bus that would have gone to the FX. Parametrically, there is no difference to the synth whether there's jacks there or not. If you were to remove the ability to set the jack assigns, you'd be removing functionality from even the P1k boxes.
Finally, as for the technology, it's sort of a hybrid approach. The basis is pretty standard sample-playback, i.e. play some multisamples, envelope them, filter them, and throw an effect or two on them. Beyond that, though, is E-mu's extensive modulation possibilities and advanced filters. The patchcord section is probably the most complicated of any ROMpler, allowing you to do all sorts of things that typically you'd only find on an analog modular synth (not surprising since that's where E-mu's roots lie). Finally, those filters are way beyond what typical sweepable Fc/Q lowpass filters can do -- 12th order filters can do some pretty crazy things. As for it being a synthesizer? Absolutely.

hey Aaron, it is nice to see an (ex?) e-mu engineer here.
it would be nice to know wether a device actually has the outputs or
not so that my software can disable the controls for setting the
subout (to avoid confusion). i was wondering about why there is no
such information about this in any sysex data. my guess is that "e-mu"
knew that this information is "hidden" in some other parameter (namely
the number of MIDI-channels) but forgot to let us know. can you
confirm that every device that has 32 MIDI-channels also has multiple
stereo outputs and every device with 16 MIDI-channels has only one?
also, can you recommend, or do you know a book about the technology e-
mu utilizes in their proteus 2000? i mean there are a lot of books
about synthesizers (moog style). but the proteus 2000 is not exactly a
synthesizer as its using sampled sound as its base, not oscillators.
what is this called; "sampling-technology", "sample synthesizer", or
just "sample-player"?
maybe i should just look into sampler technology?
thank you,
