Hi all,
New images are ready for testing (amd64, i386) ;)
io GNU/Linux is a Live DVD/USB based on Debian Sid and focused on multimedia.
-> Kernel 4.14 and 4.14-rt1, Jack2+PulseAudio as default sound server (can
be easily changed to Jack2+AlsaLoop, Jack2+ZitaBridge, PulseAudio or Alsa)

Pianoteq, the French makers of the famous piano modelings will release
next week an organ modeling. The blurb says:
"ORGANTEQ Alpha is a small organ with a keyboard range of 4 octaves
(from F1 to F5) and with 2 stops: a Flute 8' and a Flute 4' (octave).
It is provided in standalone mode only and should be regarded as a
foretaste of a more advanced commercial version in development, due to
be released during 2018."
This is a relaxed, even pensive, short piece done way out of any BPM
considerations. Completely turned the metronome off. That pesky thing.
Like a devil poking. Darn.
Sweetly pulsating, 3 minutes off the grid:

Anyone running the 4.13.15-300.rt5.1.fc27.ccrma.x86_64+rt from the
PlanetCCRMA repository with a USB audio interface? I find that my USB
interface makes output so distorted it is not recognizable with that RT
kernel, but works OK with the stock fedora kernel. I find no error
messages in /var/log/messages or dmesg when playing audio.
I tried aplay, but no error messages at all.
I thought perhaps jackd would give useful error messages, but I see no
errors when starting, but "no callback" messages begin showing up right
away. I'm stopped at the moment, I do not know how to proceed without
finding some kind of error message to point me in the right direction. Is
there any other location to find status information on USB audio devices?
This is the rtirq configuration in use:
RTIRQ_NAME_LIST="usb enp3s4f1 i8042"
RTIRQ_PRIO_HIGH=95
RTIRQ_PRIO_DECR=2
Is "usb" enough there, or should it be snd_usb in place of usb?
As an aside, I found that the IRQ priorities were not set automatically, I
had to manually run rtirq, but that is probably a fedora package problem.
Getting USB interrupt priority set to a high priority made no difference
This is the startup output from jackd:

Hey hey,
when I recorded something today - after a long time - I noticed masive xruns
during recording, not during playback. I suspected LinuxSampler with the SFZ
engine, but - as far as I could see - it doesn't use much CPU. It's still
getting so bad that I get horrible timing issues. I am recording five stereo
tracks from LS, while four more tracks are playing back. Below you'll find
system/software info. I'd welcome any tip.
Kernel: 4.13.12-1-ARCH (64bit)
CPU: AMD Athlon(tm) II X4 640 Processor (as listed in /proc/cpuinfo)
realTimeConfigQuickScan reports that the system is good, except for no full
preemtion enabled in the kernel.
LinuxSampler: v2.0.0
jackd: v0.125.0 (-R --timeout 4500 -d alsa -C multi_capture -P multi_playback
-r 48000 -p 256 -z shaped)
multi_capture and multi_playback are ALSA devices that couple two MAudio Delta
1010LT cards (linked by S/PDIF clocking)
Internal hard-drive: apparently SAMSUNG HD154UI (as found via /sys)
Best wishes,
Jeanette

I have an interesting problem. I'm using optical outputs to a d/a with 8
output channels (Frontier Tango24), but I needed 10 output channels. So
for the l/r rear channels I'm using the spdif outputs from my RME card
connected to an Orei DA21 2 channel D/A unit. This seemed to work fine,
but when testing I limited the Ecasound output to LFE only, and I noticed
that somehow the LFE signal gets sent to the l/r rear amp in addition to
the sub amp, and I hear LFE coming out of my small(er) rear speakers. (I
put a 50hz high-pass filter on them for now, until I figure this out.)
I'm guessing this might have to do with 32 bit vs. 24 bit output or
something. Here's the line in Ecasound that outputs to Jack:
-a:rear,LFE,sub_left,sub_right,center_sub,center_low,center_mid,side_low,
side_high -f:f32_le,10,48000 -o:jack
Any ideas?
Thanks,

Hi all,
I'm looking for a piano keyboard
("midi master keyboard" I think it's called).
I'm looking for something with keys that feel
more or less like a real piano. I've seen several
models, some have real hammers inside. I wonder
if that's useful/necessary to emulate a piano touch.
I want 88 keys (standard piano) and USB connection.
I want something that I can plug into my computer
and that would work as a midi source more or less
out of the box with my Debian-based system.
(I can write some code, no problemo, I do it all the
time. I just need something compatible with linux.)
So, I would like to know if any of you, preferably
someone who knows and likes to play the (real) piano,
uses this kind of devices, and if yes what model you
use.
My main idea is to have a "portable piano" because I
can't afford the real beast, plus I need something I
can use at 2am without annoying neighbours. And I want
something of reasonable quality.
Thanks!
The Casio Privia keyboards should also be considered due to decent action,
modest cost, and low weight. I have the Privia 5X-5S, though I think the
whole PX line has the same keybed so if you only want a keyboard you buy a
less expensive model like the PX-350. Not claiming this a substitute for
an actual piano, but I think it is a good value for the money. If you
have a larger budget there are probably better keyboards, but as has been
said by others, you should try out keyboards to see what you like (though
in my experience high-end midi controllers are hard to find in music
stores).
Of course, another issue a Linux pianist faces is the limited options of
good piano sounds (or any sounds). Luckily Pianoteq is available for linux
and has gotten quite good, though not exactly cheap. I am also glad I
picked up some SampleTekk gigasampler piano samples before they stopped
selling them. TBO is my favorite, though Black Grand is also excellent.
SampleTekk does sell SFZs of these, but they are not nearly as good as the
gigasampler versions. The only decent open source piano is the
Salamander grand. Quality of piano sound is mostly important for solo
playing. In mix you can play almost anything and you won't notice the
difference.
