After some recent activity on the Linux Audio Development mailing list,
I've decided to put all my Gtkmm Widgets, JACK MIDI examples etc into
repositories on Github.
Here's the links:
Gtkmm Custom Widgets
JACK MIDI Examples
Keep in mind that they're by no means "the professionals way to do it".
Also keep in mind that it does work on my machine here, any problems,
please report them back to me. :-)
Cheerio, till next, -Harry
