Misapprehension: You don't have to run a telnet deamon on your box. You only 
need a telnet client to type the LSCP commands manually or 'netcat' or 
something similar to send a LSCP script file to LS.

See attached LSCP example script.

Not yet, but there will be howtos, documentations and even up to date install 
and readme files ;) when we are near the first release (perhaps in about 1 - 
2 months).

Just a bit patience!

Benno, again: the point is not mono / stereo, the point is that the 
Gigasampler filter always consists of two biquad filters to create the 4 
filter poles. Maybe with another filter algo there other ways but AFAIK not 
with biquads. Correct me Steve if I'm telling something incorrect!

So, a Gigasampler LP filter in LS is actually one biquad BP + one biquad LP, a 
Gigasampler BP in LS are two biquad BPs and a Gigasampler HP is... guess 
it... yes, a biquad BP + a biquad HP. Means we still need 10 coefficients!

Anyway, I think we'll stick with the matrix idea and let all (10) filter 
coefficients be calculated outside the render loop and within the render loop 
we just read those 10 coefficients from the synthesis parameter matrix.

I think there will be machines where one approach might be more efficient than 
the other one, so in long term of course the user will be able to choose 
between e.g. either the matrix or in-loop event solution, preferebly done 
automatically by some benchmarking routine on his host, controllable by a 
nice GUI.

Christian

P.S. I guess for the not yet implemented so called "turbo low pass" filter of 
Gigasampler, we'll need even 3 biquad filters, means 15 filter coefficients, 
not sure yet

Currently I have very little time on the internet. If someone can pass me a 
quick example of how to load a gig file and set it's MIDI and audio outputs 
I would greatly appreciate it.

A good topic for a HOWTO somewhere?

I hope someone will add the make -f  step to the INSTALL file since it is a 
non-standard build practice. (Although becoming more standard.)

Re: [Linuxsampler-devel] Filter code optimization, sinewave .GIG files request

Hi Benno,

I'm working on something that works in the first place; whether it's nice
it's kind of subjective ;)

But,... tada... I have already something that you can look at:

It's qsampler!

OK. It's still in prototypical alpha stage i.e. it doesn't do anything
useful, but it surely is something you can preview for the intended
look-and-feel right now.

Qsampler's project is hosted on sourceforge.net and it's preliminar CVS
repository can be checked out through anonymous (pserver) CVS with the
following instructions:

  cvs -d:pserver:ano...@cv...:/cvsroot/qsampler login

when prompted for a password, you'll know what to do: just hit enter.

First, you'll need to install the liblscp package. This is for
LinuxSampler Control Protocol support library, which qsampler is based:

  cvs -z3 -d:pserver:ano...@cv...:/cvsroot/qsampler co
liblscp
  cd liblscp
  make -f Makefile.cvs
  ./configure
  make
  make install
  cd ..

This will install liblscp.so under /usr/local/lib, so be sure to have it
registered on your shared library path.

Then, you'll may try with qsampler itself.

  cvs -z3 -d:pserver:ano...@cv...:/cvsroot/qsampler co
qsampler
  cd qsampler
  make -f Makefile.cvs
  ./configure
  make

then run ./qsampler and you'll see what I've been cookin' :)

These instructions are for linux of course. But win32 support is also in
the box. If someone want to try

Hope you enjoy,

[Linuxsampler-devel] Filter code optimization, sinewave .GIG files request

[<be...@ga...>]

Christian and I talked about how speed up the (LP/HP/BP etc) filter code.
Currently it's suboptimal because UpdateFilter() does an if() and a %
at each sample.
The a better method is to use the sythesis matrix like for pitch
and volume.
some issues: currently LS does use two separate filter instances
in case of stereo samples, but this wastes CPU since AFAIK
in other samplers filters on stereo samples are applied equally
on both the left and right channel. So you still need to run this code:


            inline bq_t Apply(const bq_t x) {
                bq_t y;

                y = this->b0 * x + this->b1 * this->x1 + this->b2 * this->x2 +
                    this->a1 * this->y1 + this->a2 * this->y2;
                KillDenormal(y);
                this->x2 = this->x1;
                this->x1 = x;
                this->y2 = this->y1;
                this->y1 = y;

                return y;
            }

two times (for each of the stereo channels), but
the coefficients can be shared thus if the filter code gets implemented
into the event synthesis matrix then instead of transfering 10 coefficients
at time two times (a1,a2,b0,b1,b2) you need only 5 and the L1/L2 cache
will say a big thank you :)

I'm still curious if transfering 5 coefficients/sample from memory is
faster than placing a conditional in the event loop and check for filter
updates which recalculate these coefficients (filter events should be
relatively sparse).
As said more benchmarking is needed here, but in the meanwhile since
Christian's event matrix is already working fine I'd say he should go ahead
with his solution. (but Christian make sure to use shared coefficients for left
and right filters).
At a later stage to speed up things further we can write a SIMD version of the
filter (SSE etc) which is especially useful in the stereo case where full
parallelism can be achieved.

http://www.northernsounds.com/ubbthreads/showflat.php?Cat=&Number=162226&page=0&view=collapsed&sb=5&o=&fpart=1#162226
Even if I'm currently not contributing code (only some ideas) at least I do some
PR for LS :)

Rui, I told northernsounds.com users that you are writing a very nice GUI, don't
disappoint them :)


Mark: about the ML archives, you are right, for some strange reason the last
months are missing (while on other projects the archives are ok).
Anyway I think the SF.net archives are buggy anyway so we should probably
simply subscribe an other ML archiving site to


About initializing LS via the LSCP, this is what Christian wrote some time ago:

> The easiest way currently is to write a LSCP script and to send it via
> netcat to the running sampler:
>
>        cat yourscript.lscp | nc -t localhost 8888

you must construct your own yourscript.lscp
I'm not sure if it makes sense to ship some default lscp script for now.
perhaps some 1-2 channel example but it would need to be tweaked by the user
anyway. If you want after some experimenting you could contribute such a script
and some small README how to tweak it as the lscp PDF is a bit heavy to read :)


PS2: there is still this nasty aliasing bug in LS,
enable cubic interpolation (happens with linear too but let's use cubic
to rule out problems in the low quality interpolation code) load a piano sample
and play high notes at very low velocities, keep them sustained, you clearly
hear an aliasing noise floor which will fade away when the voice finishes
playing.
I tried to track it down (tried to remove the envelope section, did check
the mixing code) but I did not find the cause yet.
If some GSt user has some time, he could you produce a few .GIG files a non
looped pure sinewave at 0dB (full scale), 30secs of lenght, both a mono and a
stereo version. make a version with 440Hz root note and one with 3520Hz. (which
equals to 440Hz shifted up 3 octaves).
So basically 4 GIGs. In this case we can benchmark the quality of the
interpolator too. (take the 440Hz sample, play it at high pitches and check
the output, take the  3520Hz sample and play it at low pitches to see if the
wave's shape looks still good.

You can zip them together and mail them me at
sb...@ga...   (I have no space limits).
and then I'll make them available on the LS site so that other people
can perform tests too.

thanks,
Benno

Ah! just like Rosegarden. I'll give it a try...

...and it worked. Good

However, I did read the INSTALL file and it didn't tell me that I needed 
to run the make -f Makefile.cvs step so (shaking my index finger) shame 
on you developers! ;-)

Now, I'm trying to run it but there are no instructions that seem 
targeted to silly users like me. It just starts a LS server and sits 
there. I guess I need new instructions on how to use it since it's 
switched to the client/server approach. I see 3 linuxsampler --help 
processes in ps aux.) man linuxsampler returns nothing.

linuxsampler --help returns no info and starts the program.

There are no other executables in the src directory.

The testcases directory has nothing that I understand.

Where's the instructions guys?

I have no clue, I also wondered a while ago, but didn't really care about. I 
guess we will also move the mailing list in one or two months. But of course

[Linuxsampler-devel] List archives

Why do the Sourceforge archives have no messages more recent than 
2004-03-30??????

The current CVS is not building for me. I wanted to check the archives 
before I pestered people here.

Thanks,

And I would be happy to offer this. However, in the very short term I 
have just moved this week, my studio is packed in boxes and will not be 
rebuilt until at least mid-July. I *probably* can get my GSt machine out 
of storage and do a little bit of work before June 8th as I'm in a small 
rental house right now, but following the 8th I'll lkely be living in 
hotels or just going on a small vacation to pass the time until we get 
the new house.

I am setting up GSt on my laptop with the hopes of using it and 
Rosegarden together over the next 4 or so weeks. I did copy most of my 
gig library to the laptop with this in mind.

This is all nothing but plans. Moving is quite stressful and I seem to 
have no energy to do anything except vegetate in front of the TV the 
last 3 evenings. ;-) I do hope it will get better. ;-)

Are you talking about me? :) (Marek/Mark)

What i can offer is tuning with my precise ear. :)
What i can't offer is side-by-side comparison of LS and Gst as i have to
admit that:
1. I don't have a legal copy of Gst,
2. I have never used it,
3. i don't  even have windows installed at all (yes, i'm one of those 5%
linux desktop users :)

The best thing would probably be to make all values that are subject to
tuning available via a GUI so that non-programmers can tune and provide
results. For side-by-side it would probably be the best to have 2
separate machines one running Gst, one running LS...not sure, depends on
the type of values that need to be tuned.

To keep it all clean from a legal POV, it would be good to find legal
Gst users such as Mark, which could lay their hands on tuning.

Multi engine / channel support is alread done. You can create / remove sampler 
channels, deploy an engine for each sampler channel, select an audio output 
system individually for each sampler channel, but we currently support only 
one MIDI input system which is Alsa. So I was more interested if the idea of 
e.g. VSTi as input and Alsa as output makes sense or if you think it would 
technically make to much problems.

And what framework do you mean?

Yes, actually once the current linuxsampler is more mature
I will port it as an engine to our framework, so we can
definitely have multi engine on a per-channel basis.

Hi,
I think for now it does not make sense to invest too much engergies
into solving these issues.
multi engine is fine but (eg running GIG and AKAI engines in parallel)
but for now it makes more sense if these engines can output on the
same audio out (jackd, ALSA) and get the MIDI input from the same
source (currently ALSA seq).
These features would make most of the part happy.
have you ever heard about multi engine, multi audio/midi device support on
a per channel basis etc on Windows/Mac samplers ? 

Ah and then what's needed it tuning the GIG engine to make
sound the GIG files right.

Marek said he will volounteer to this task (A/B comparisons etc).
But I guess for achieving perfection a group of several people will be needed
(with good knowledge of GSt, good sense of analysis, perhaps some
programming skills to fiddle with the LS codebase when trying to adjust
tuning, velocity curves etc).

I think in particular the Garritan samples (GOS Lite) which was made
available to a number of core LS developers, are a good testcase for
optimizing the GIG engine. when GOS works well I guess almost all other
GIG files will work well.

cheers,
Benno

[Linuxsampler-devel] batch oriented (e.g. VSTi) vs. just in time (e.g. Alsa) rendering

[Christian S. <chr...@ep...>]

Hi!

As you might have seen, it's planned for LinuxSampler to allow arbitrary 
connections for each sampler channel, means for example a sampler chanel 
could use VSTi as MIDI input and Alsa as audio output.

This means a couple of problems: different fragment sizes for MIDI input and 
audio output system, remapping of the MIDI events, jitter, sync problems, 
etc.

So my question is, do you think this is technically nonsense?

Yeah, cvs is a bit bullheaded. ;)

Sorry for the simple questions, but I cannot seem to checkout 
singlechannel based on the instructions on linuxsampler.org. The main 
page states to add '-r singlechannel' to the standard cvs command, which 
the downloads page states is
cvs -z3 -d:pserver:ano...@cv...:/var/cvs/linuxsampler 
co linuxsampler
I have tried a bunch of logical permutations of this but continue to get 
cannot find module 'singlechannel'.
Any suggestions? Thanks. -Garett

Re: [Linuxsampler-devel] specify alsa device?

[Vladimir S. <ha...@so...>]

Hi Garett,

For now it is probably easier to check out single channel version and 
try that. It has a cmd line switch to pick alsa output. Multichannel ls 
is a work in progress and there are a few things that are a bit in flux 
at the moment.

Regards,
Vladimir.
