#55 add Jack capability

[Robert Keller]

A "Jack" capability for Linux users has been requested. Please figure out what this would entail, then design and implement.

[Collette]

I vote for this one.

I vote for this, too. Lack of Jack (or ALSA) is a bit of a nuisance.

There are some java jack wrappers around, which presumably should help, though I don't know which work well :-/

JNAJack: https://code.google.com/p/java-audio-utils/

jjack: https://sourceforge.net/projects/jjack/

jack4j https://sourceforge.net/projects/jack4j/

There's a JavaScript kit: https://github.com/unclechu/node-jack-connector.

JNAJack is mentioned on the Jackaudio site as useable with the Windows version of Jack, which suggests to me that it may be the most suitable tool:
http://www.jackaudio.org/faq/jack_on_windows.html

The Jack API documentation is here:
http://www.jackaudio.org/api/
though I don't know how well that relates to the java interfaces.

IMHO Inpro-Visor would really only need a MIDI output, though I could see a midi-input and the means to sync In/Out may be useful. Others may have other views.
