My questions:
How can I force my system not to handle the Korg as an audio but a MIDI
device?
Your system(kernel) wont listen, I am afraid, you could only blacklist
the Korg, but that is stupid, because I reckon, you want to use it.
BUT you can tell Jack explicitly to use the HammerfallDSP as in:
jackd -d alsa -d hw:2 -p128 -n2
This commandline can be stored in $HOME/.jackdrc to serve as the default
for the start of jackd.
To make this independent of discovery order:
jackd -d alsa -d hw:DSP -p128 -n2
:~$ jackd -d alsa -d hw:DSP -p128 -n2

Okay, then I have to tell more about my system…
Unfortunately, I'm not using it on my own. My machine is also
extensively used by my son and, surely, he is no friend of the command
line. We use the wonderful Cadence to make everything just work after
login (which includes watching youtube-videos via FIrefox and still
getting the output over the highend soundcard and monitoring). So,
Cadence is configured to start jack and deliver a pulseaudio bridge. And
there must be the problem, cause everything works, as long as the Korg
isn't plugged in at startup. Otherwise, I (or he) have (has) to launch
jack via commandline. (I could tell him not to plug the Korg, until
everythings up, but I thought t here could be something to do which
makes the problem just go away…)
Greets!
