I did put in a bit of a suggestion to tackle precisely this challenge.
But i'd wager that enabling lilypond to "show" its ports in something
like jackd is a bigger job than users would envisage.
It would require, in something like the midi block (or a new block
structure), the ability to assign port/bank/patch per staff, and per
instrument/note.

So the default would be as it is now, but when the "\JackMidiPort", or
"\AlsaMidi Port" block is added, it exposes those ports directly to a
patchbay, instead of being invisible.

Assuming \JackMidiPort, the block might look something like the following:

\JackMidiPort
       <<
             \JackMidi1stViolins-port0
             \JackMidi2ndViolins-port1
             \JackMidiViolas-port2
                etc........
        >>

Each port has 16 channels (of course), so the user can then assign one
of the ports to his instrument block.

In a perceived use case, the user could then assign bank and patch per
note, with something like \BankMSB, \BankLSB, and \Patch followed by
the desired integer.

All ports for a project, when the project is loaded, would show up in
your patch bay (and stay up, not disappear and re-appear), and you
could send the ports wherever you wanted, in my case, Linuxsampler,
and my somewhat substantial sample libs.

And because each port has 16 channels, the use could alternatively, if
he wished, use instead a command like \MCha (midi channel) followed by
a channel number to switch channels per note.

As i wrote in the initial suggestion, i have no idea if this is
feasible or possible in code terms.

I would particularly like to see something like this in lilypondtool,
as it's become almost a complete compositional environment for me,
only the playback remains a challenge.

p.s. Gentoo 64bit linux here, if that changes anything.
