Yeah.
In the old days, you'd have a sample of one note, and change the
playback speed to get different notes. If you were really flash, you'd
have samples of several different notes, so you don't have to bend the
pitch too far. Trouble is, then as you run up or down the scale, you can
hear where the software switches from one sample to another.
Of course, those days are long gone. Each Kontakt instrument has at
least one sample for every single individual note. For something like a
piano, where every single note naturally sounds very slightly different
(and has a different stereo location), the result is very impressive.
In addition to that, you have "velocity layers"; rather than just
adjusting the sample playback volume in response to harder or software
keypresses, you actually play a different sample. (Of course, MIDI
allows 127 different velocities, while a typical instrument has only
perhaps 6 different velocity samples for each note, so some volume
mapping is still used to go between. Personally I would have thought
cross-mixing would be more accurate, but what do I know?)
Then of course some instruments have a characteristic attack, or even
release (harpsichord). And some have infinite sustain (generally wind
instruments), so you have a looping sample in the middle. Rather than
have text boxes to type in sample names, Kontakt has some sort of
scripting language to control what the sample engine plays. This
obviously allows a lot more flexibility.
As if all that wasn't enough, for some instruments they record them with
4 sets of microphones, placed at different distances from the sound
source. So you can hear a piano up-close and personal, where you can
hear the sound of the keys, the muffled clunk of the dampers, and
everything. Or you can hear a distant piano, where the notes are as
clear as day, but not the mechanics. Again, this isn't filtering, this
is multiple sets of samples.
On top of *that*, you can have the piano lid open, half-open or closed,
which obviously radically alters the sound.
So for the piano instrument, you have: 3 lid positions * 4 microphone
distances * 12 key velocities * 88 notes on the keyboard, yielding a
total of 12,672 individual samples. (Can you *imagine* how boring it
must have been to record all of those??) No wonder each piano comes on
its own DVD! (There are 4 different pianos, remember...)
The pianos also support different tunings - but *that* is done in
software. (E.g., you can have a piano with Pythagorean tuning if you so
desire. In solemn truth, it makes scant difference to the sound.)
A similar thing happens with, say, violin. 4 sets of microphones. The
players play each possible note, as softly as they can. They play them
all again, slightly louder. And so on, until they're playing as loud as
they can. Then they play again, tremolo style. Then again, pizzicato
style. Then again, sforzando style. And so on.
For harp, there is "normal" and "flageolet" (slightly muted). Some of
the instruments have just one articulation. Some (e.g., harpsichord)
have only one velocity layer.

I'll take a look when I go somewhere with sound capabilities.

The goal of a compressor is to very subtly enhance the sound. Which
makes it all the more amusing to see a "fully authentic emulation of the
iconic sound of this vintage compressor". If the compressor is any good,
it doesn't *have* a recognisable sound! :-P
Also, I suspect that if all of your sound sources are algorithmically
generated, you probably don't *need* a compressor in the first place.
You can just change the volume envelope of the sound source directly. A
compressor is more useful if you're trying to record live real-world sounds.

So I can pay a hundred pounds for the software on my PC, or 1/20th of
that for the exact same program on my phone?
Either one product is vastly overpriced, or the other is an absolute
bargain. :-P
(Then again, given that an iPhone presumably costs more than even the
most expensive PC in the first place... maybe not.)
