Hi
I'm glad you've got it worked out -- as I mentioned in my previous
message, I have had MrRay73 working with (much) earlier versions of both
dssi-vst and FST so I was surprised that it wasn't still do-able.
Anyway, I'd just use the transpose buttons on my Edirol PCR-80, but if
you don't have such features qmidiroute should do what you need. I've
found it very useful for splitting my midi controller for playing dual
manual organs like Hammond or the fantastic Aeolus.
Thanks Q,
but my Clavia keyboard can't transpose outgoing notes, so I tried to
find qmidiroute. No Debian package exists, so I extracted the binary
from Ubuntu's qmidiroute_0.2.1-0ubuntu2_i386.deb and it works perfectly
under Debian/squeeze.
The last problem was to get a realtime-kernel. Alas Debian has no
RT-kernel distributed (top of my personal wishlist in Debian!!!) :-/
But a nice person packaged a rt-kernel here (thanks a lot!):
http://www.bandshed.net/AVLinux2/kernel-rt-highmem/linux-image-2.6.29.4-rt1…
which I found mentioned in the ardour forum:
http://ardour.org/node/2653#comment-12674
I had a running linux-image-2.6.29-2-686 and installed
linux-image-2.6.29.4-rt15-rt_2.6.29.4-rt15-rt-10.00.Custom_i386.deb with
dpkg -i. Grub and initramfs were updated automatically.
The only configuration I did was /etc/security/limits.conf:
...
@audio - memlock 512000
@audio - rtprio 99
@audio - nice -10
# End of file
Realtime now works on my Asus eeebox (similar to eeepc). I plan to
dual-boot with this RT-kernel only for making music with my keyboard. In
all other cases I will use/boot the stock Debian kernel.
MrRay73.dll with dssi-vst runs fast and without any xruns on this setup.
Only some noise from the mainboard (hd-controller?) pollutes the
line-output. In the long run an external usb-soundcard should do the
job. A harder test seems to be the fabulous pianoteq piano, which was
released recently as native linux software (bravo!). I installed the
demo today on my new setup and it runs, but I have to read a little
about optimizing jackd and RT, as it uses more ressources.
