Hi Jeremy,

Hi Carlos,
Try resetting the JACK buffersize with jack_bufsize after
starting your program. This does the trick for me on the RPi.
It seems it did my trick as well, great! For the moment sound seems
to be as clean as it can until the moment I debug other inner
noises (it sounds like that of physical hard drives turning, but
there's none in RPi (?)) when nothing is plugged in the audio
interface.
Now, there's just a minimum issue, but I can live with it.
Rackarrack runs now as "pi" user and it should take its
configuration from user's $HOME, that is what it should be
"/home/pi", but it seems that it doesn't. The difference between
running the launcher script when logged in as pi is that it takes
the MIDI mapping configured in preferences, but when launched
automatically on init phase it takes the default MIDI mapping.
I run the launcher script from the service script with: su -l -c
$STARTPATH/launcherscript.sh pi
...and "-l" should load the pi environment (I checked it when
debugging). Maybe is something specific with Rakarrack.
Thanks so much, Jeremy.
I'm using 'su -l pi -c /some/command' myself but the order shouldn't
matter I guess. Otherwise you could take a look at start-stop-daemon.
Examples can be found in /etc/init.d/skeleton
Jeremy
