It should be possible to do this with AMS 1.7.x, but I never tried.
There's a limit to the number of JACK ports (32 IIRC), but this is
compile time defined and can be increased.
But nothing is gained by doing all routing through JACK, and for
polyphonic patches this could become a nightmare (currently they are
mixed down at the JACK port).
In a similar way, AMS 1.7.x supports multichannel ALSA devices, and if
these are DC coupled you could use them to send / receive control voltages.
