Re: [fluid-dev] New JACK MIDI driver and other stuff

[Josh Green]

Cool, just wanted to make sure ;)  I get temporary amnesia sometimes
from having so many projects.  That sounds like the right solution.
Thanks again guys for everything you have done on this last development
cycle.

I'll be pretty busy tomorrow, so its looking like Wednesday before I
have some time to put into making a release.

Cheers!
