Do the separate audio streams created by this process

ever get mixed together?
If so, is there a reason for the mixing to happen under

JACK, rather than within midi, where command line sequencer

such as midish can do the job?

So I had to loop over all open PIDs and kill them which produced xruns and jack hiccups, it also took long.
