This patch adds JACK MIDI support to ZynAddSubFX 2.2.1.
If you build Zyn with JACK audio output you will also
get a JACK MIDI input port that you can use at the same
time as your other MIDI input port (only tested with ALSA).
This will of course require an installation of JACK
with the patch available on this page:
Sample-accurate MIDI is not supported in this patch.
This patch does not work together with the LASH patch,
if you want both LASH and JACK MIDI you have to use the
LASH + JACK MIDI patch (also in this patch tracker).
