Ah, yes, silly of me. I was indeed mostly trying the GUI and getting a bit=
=20
confused with naming conventions and things.

I got it working finally, lovely! Still a bit to go but=20
getting closer all the time ;).

As you might know the thing I'm trying to get to work right now is Drumkit=
=20
from Hell. First I note that linuxsampler takes 204mb of memory when loadin=
g=20
both the close and rear micked kits. Instinctively it's a bit much but then=
=20
again there are alot of samples...
I got it to crash quite easilt also, just playing this setup, I will=20
investigate this more.=20
I also had X vanish a few times while testing linuxsampler. My guess is tha=
t=20
linuxsampler gets kicked/crashes from jack, jack freezes qjackctl, somethin=
g=20
bad happens, qjackctl-->X-->poof.

Ahh, here's a backtrace of one of the crashes, seems mostly unusable though=
,=20
optimized binary I presume, I will compile for debug later:

As for drum specific things, it is common in drumbanks to have the hihat on=
=20
several keys (as is the case here too), since a hihat is monophonic by natu=
re=20
these keys are often grouped together so only one of them can produce sound=
=20
at the time.
This does not seem to be the case here, I have no idea how things like this=
=20
work with GIG files or if it is at all possible or if the bank infact is=20
programmed for this. But my gut feeling is that it should be possible and=20
that the bank should support it.
The remaining question is then: Is it known how this works in the file form=
at=20
and is it implementable?

There are other ways to solve this so I'm not stranded but it would be good=
 to=20
know if this might work later on.

I noticed the ECHO ON in the script which is a good thing indeed. Would it =
be=20
possible to extend this to outputting text in the terminal on the server si=
de=20
also?
I'm not sure if it's the right way to do it but I imagine it would be quite=
=20
usable for debugging when running the GUI and linuxsampler in separate=20
terminals. I would for sure have liked it while trying to get the GUI to=20
dance.

All for now, keep up the good work!
