Hello Everyone!
I recently started having problems with my Linuxsampler. I've seen that ones
before at a friend's place, but never had it myself. I'm currently running
LinuxSampler 1.0.0.cvs10.
Especially when I load a big piano and use the sustain pedal, after a while
notes keep disappearing. I may hit them and hit them again and then they will
play. Even if I lift up on the pedal, the problem keeps persisting. I have to
completely reload the instrument, which is a bugger, since it takes ages. And
that way LS isn't useable anymore in recordings. It's not reliable. Does
anyone have an idea, why that is, if I may change something in my setup to
prevent that? Or is there a fix already?
Kindest regards
Julien

Hi Julien,
alsa or jackmidi?
I believe we have seen some issues with linuxsampler and jackmidi
together with MusE. I think there were buffer overflows. As I recall
the buffers were increased in linuxsampler at that time.
Regards,
Robert

Hello Robert!
It was alsa MIDi and played life, so no other software in between, recordng,
buffering or otherwise mangling the data.
Kindest regards

Perhaps totally off the point, but are you sure that there are enough voices
available in LinuxSampler to play back all your notes? I've had similar
symptoms when running with 4 voices or so, and then suddenly the oldest
notes start to disappear when playing quick passages.. ?
Perhaps linuxsampler doesn't even have a voice limit... I dont know :-D
Just thought I'd mention that though. Cheers, -Harry

can't be that. Because as I said, I let up on the sustain pedal and after
that everything went totally bonkus. Notes would disappear all over the place.
when I started playing LS no problem, playing quick bits, holding full chords.
But it mostly happens after I played something with high note density and held
sustain pedal. And it wasn't old notes going, but new notes not triggering any
sound.
Warmly yours
Julien

As a rule for Linuxsampler I always use all current CVS versions. Often
the bugs found in distro versions are gone in CVS.
Possibly this might help.
Thanks!

i Christopher!
I'm with you there. I compile allmy major audio software pieces from source
and try to use the recommended - newest - versions. But I had that problem
this year in Feburary, so it seems to have been there for a bit. My versions
is from mid-march.
The version I had before, didn't have that.
Another note: In the meantime I switched systems (new CPU) and kernel (from
2.6.30 to 2.6.38). No problems with any other software so far.
My previous Linuxsampler version was 1.0.0 release, I had that for some
time.
Kindly yours
Julien

What piano are you playing with, what is your system
spec?
What did you configure linuxsampler with when compiled?
Jackmidi has always given me far superior results.

Hi Christopher!
I use alsa MIDi, because on the command line, there's not much, that can use
JACK MIDI yet. Wel, there are other softsynths, but if I want to use filters
or MIDi sequencing, I can only use ALSa.
Beyond that, I didn't touch much. Increased accuracy with the subfragment
size, enable rt-exception, but didn't touch anything else in the synth section
(voices, streams, preloading...).
Warmly yours

I think at this point I would start tweeking voices and
streams.
Try compiling with greater numbers to see what happens.
Trial and error :)

OK, as much as I dread to, since it takes somuch time... :-) and I've seen it
crash on me. But I think that was due to increased preload.
although correct me if I'm wrong; It shouldn't really matter, how big my
original sample is. If I say: preload 32768 samples, then that should always
be the same, considering the format (16 or 24bit taken into account)?
I will have to postpone that though, until I have fixed my buggy CPU cooler,
it started acting up today.
Thanks so far, I'll let you know, what happens...
Warm regards
Julien

I've had the same problem as Julien and his friend, with the same
version (1.0.0.cvs10) -- it's not a system spec problem: I have a Phenom
9550 Quad-core with 4 GB RAM.
The Sampletekk Black Grand pianos are large, but in the past I've had
two loaded at once without problems on lower spec machines. It's only in
the last few months I've encountered this problem.
It'll be fine for a while, then all of a sudden you notice that some
notes you play just never sound whilst others are just fine or continue
fine. I first encountered it with a harp which is pretty lightweight,
but there were lots of notes in quick succession (this was midi
programming rather than live playing, but I've had it with live playing
of pianos as well). I have LS set for 256 voices and 120 disk streams,
which I would have thought was enough, I've managed fine with fewer in
the past.
