The extra resources are minimal and are not "wasted" they are used to provide
extra speed.
I cannot predict how many cores my users PC's will have so the synth.cpu-cores
setting is useless. Even if it adjusts itself to the real no. of cores a user
has it provides no guaranteed benefit over using four instances. Each division
of an organ is pretty much identical so I use the benefits of c++ code to reuse
the identical code for each division including processing the synths. Four
instances of FS will run perfectly well even if the users PC has only one core.
The four stereo outputs are automatically provided by using four synth
instances. And are simple for users to understand and use. Thus the additional
complexity of "multi-channel rendering" is avoided. (Though I may come back to
this later, in order to get even more outputs, if and when I get some spare
time)
I was only experimenting with V2 in order to get my tremolo working. I am sorry
to say my experience of V2 (different, more complex API and all the extra
.dlls) put me off using it for now. I used a precompiled version because that
was easiest at the time. My previous experience of compiling FS on Windows was
very time consuming - hopefully you have now made it easier to compile. I have
other more useful things to do at present.
FS V1.1.8 may have bugs (so does all software) but the bugs are so well hidden
that I have not noticed them. They certainly do not and never have crashed my
App.

Four instances are pretty much four times more wasteful on resources
than a single instance. The synth has a built-in parallel renderer,
you just need to use it:
fluid_settings_setint(settings, "synth.cpu-cores", 4);

That's not a reason either as the synth supports multi-channel
rendering. Sorry, I think you should not claim to understand the
synth.

The "host of dlls" strongly depends on the environment used for
compilation. That said, V2 does not have any extra dependencies!

V2 provides (completely useless) bug fixes for an organ. V1.1.8 could
crash your entire app...
