Yes, maybe I should mention it somewhere.

This looks like a problem with JACK, you will probably get the same
message from any JACK client. You don't have your system set up to allow
your user to lock memory, which JACK clients need to do to run in
realtime.

Not sure why you get this, from the Dino output below Dino obivously
connects to a running lashd so it must be working somehow.

Are you running it with the Dino source directory as current working
directory? For some reason it doesn't find the installed graphics files
when you do that, but it's easily worked around by just changing
directory to somewhere else.

Again, a JACK client (Dino this time) is for some reason not allowed to
lock memory and schedule its threads to run with realtime privileges.

This is all normal. Most of it is chatter from liblash, and the last
line is related to the LADISH support and can safely be ignored if you
don't use LADISH.

This menu lists the available JACK MIDI input ports on the system. Do
you have any programs with JACK MIDI input ports running, or are you
telling JACK to mirror your ALSA hardware or sequencer ports (the -X raw
or -X seq options to the jackd alsa driver) ? If not, the menu will only
show the option "None".

MIDI output ports are created for every track in Dino, so if you have
added any tracks they _should_ show up in the MIDI section in QJackCtl.
