ALSA Patch Bay
This is a GUI patchbay for the the ALSA seq sequencer api and the JACK audio API. It can use FLTK 1.1 or GTKmm 2.0.0. If you have both installed, you can specify which to use with the --ui command line option. The --driver command line option selects the driver. Alternatively, there should be a jack-patch-bay link installed which points to the alsa-patch-bay binary and will automatically load the jack driver.
