This is actually difficult to answer, because I'm not familiar
with traditional sampling terminology (I find it to be generally
impenetrable when I do encounter it). Specimen has no notion
of an "instrument" per se. Its vocabulary is as follows:
* Patch: a sample and the parameters controlling how it should be
played. Later, patches will be given the ability to contain
multiple samples.
* Channel: there are 16 channels corresponding to the 16 standard MIDI
channels. Each channel can have any number of patches assigned to
it (so long as that number doesn't exceed the global limit on
patches).
* Bank: a bank is the collection of all 16 channels and any global
parameters that have been set.
So, an instrument might be just one tb303 patch. Or it might be a set
of patches on Channel 3 that serve as a drumkit. The choice is up to
the user.
By default, Jack outputs are provided at the Bank level (and they must
always be present). The plan is to allow channels and patches to have
Jack output themselves, if the user so desires, on an individual
entity basis.

qjackctl. I'm not interested in creating Yet Another Routing System.
Better to do it once and do it right.

I don't think I follow you here, so understand if my response seems
asinine.
Specimen creates a pair of master outputs and connects them to the
first set of available hardware outputs that it finds, but you're free
to connect them to whatever you want.

Always appreciated. I don't like operating in a vacuum.
