Its Jack compatible and can include LADSPA plugins. I tried it, but it wouldn't start since I don't use the ALSA sequencer modules. I wrote a patch to fix that (attached) - if it can't open the ALSA sequencer device it will simply not use MIDI, otherwise everything should work normally. Also, the JACK compatibility only extends to audio. It would be pretty nice to have sample-synced JACK MIDI support. Another wishlist item: LASH support. --ll
