[Guitarix-developer] release guitarix2-0.17.0

[hermann <bru...@we...>]

Hi

I have pushed out a new release today, to fix a issue with jack session.
This release also fixed some build/runtime issues on OSX. 

Also I have committed the rest of the source reformation. The source is
now clean to the Google C++ Style Guide convention at -v3 checked with
cpplint.py

So, zita convolver performance depends hardly on the jack buffer size,
to compare IR Reverb and guitarix convolver you need to run them on the
same jack buffer size.

Try it :-) It didn't depend only on how large the file is, also bit
format and value play a role,

Well, so a possible solution could be to make the auto resample function
selectable, so, when files fail, you could switch of the resampler and
use them in the original sample rate, that's, for example how IR Reverb
do it. I will do that.
Maybe I found a better solution once, it's a bit tricky to resample in
realtime, special when large files are involved. Also, it isn't easy to
check if the resampler fail in that stage, otherwise we could do all
that automatic. 
For now, I could only put it on the todo list, I need a brainstorm to
find a better/saver solution then the one we use now.

This is the same file that I had issues with way back when the project

And, to the repeating delay, what is about Xruns, do it produce Xruns ?
If so, you need to increase the Jack buffer size to be able to run those
files.

The ones that never worked before, but other files worked like before,
without a repeating delay ?

works now but now the IR file have a delay... they all have a repeating

[Guitarix-developer] Source code format and style

[hermann <bru...@we...>]

Source code format and style, yea, well, I'm not a professional
programmer, nor have I learn it somewhere. I learn by doing it and try
my best to reach acceptable results. 

Often I think about the source formatting and style cheats, but there
are so many out there in the wild that a decision isn't easy.

Anyhow, when we work on the source it will be helpful to use a fixed
format and style. 

So, I found now the  Google C++ Style Guide, witch seems to be nice to
me. 
 http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml

There is a python script (cpplint.py) included witch will check the
source files and identifies many style errors. 

I have started to convert the guitarix source to the style guidelines of
cpplint. The headers are converted and committed, the .cpp files should
follow.  

Hope that it makes the source a bit more attractive and better readable.

I have committed the hopefully fix today. In the jconv settings widget
you find now a new toggle button "Auto Gain correction".
Therewith you can switch the auto gain correction on/off. If a file
wouldn't work proper, switch auto gain correction of and try again.

To the auto gain correction, it's a kind of normalize algorithms to
reduce the influence on the overall gain. Unfortunately it seems that
the algorithms fail when files with a long reverb part in use.
 
The gain line (green line on top of the wave view) will work in any
case, so you can use it, also when the auto gain correction is off. 

Auto Gain correction isn't a realtime option, so you have to press apply
when you change the setting during the convolver is running.

Well, I found the reason. We use a auto gain correction witch wouldn't
work well with files with a large reverb part. ( So looong line near to
0 in the linear view)
I will add a option to disable the auto gain correction, those files
will work then.

You mean the plugin-bar? Or is there a way to have a conventional 
GTK-toolbar too?

I am not that happy with the screenshot either. The problem is, that 
gx_head is at least 1000px wide if the plugin-bar is on. In the end I 
think, I will make a sc with rack ordered vertical...

> and yes, when you send me a user/passwort I will contribute.

on my way ;-)

This is just a matter of a bit of time inserting it in the database. 
Since we can have screenshots/img-tags in the tooltipps, one can easily 
make a screenshot of the menu expanded and insert it in the table.
It would be nice though, to have an opportunity to make subtooltipps 
that only appear, if a root-tooltipp is expanded.
This is just a bit more coding especially for the editor and we need one 
more table in the db for that to do it right. I intend to make this in 
July/during vacation - fun work to make me smile a bit more, so my 
family will tend to accept it ;-)

That's cool, indeed a nice and easy way to clear and explain some
things. 

Could you include a full expanded screen-shot, with the toolbar also,
and yes, when you send me a user/passwort I will contribute. 

It is also possible to expand the menus when move the mouse over
them ?  

well, really nice. :-)

[Guitarix-developer] New gimmick for the documentation

[Hartmut N. <zet...@li...>]

Hello,

I have made up a little app that could help to explain the GUI of 
guitarix to the users:

http://guitarix.sourceforge.net/index.php?page=6&p_type=gui

the app uses sqlite via PDO and thus we can edit and add zones to the 
screenshot that can pop up explanatory tooltipps:

http://guitarix.sourceforge.net/guiedit.php

If you want to try it, I'll gladly send you a valid password offlist.

The thing is of course initial only. It lacks some functions that should 
be there and the workflow is not entirely perfect ;-)

Anyway, I would be happy to get some comments and even more I'd be 
interested in contributions to the contents of the tooltipps. Stuff 
like: What exactly does the Master-knob as we have the fader in the 
Output-bar also?


You may find it a little daring, that I have put this unfinished piece 
directly on the sourceforge-page. The reason is, that I could not find a 
simple way to insert the database-file in the sf-page. PDO seems to 
reject writing on files that are uploaded via FTP. So we need to work 
with a database-file that is created on the sf-page by PHP.

If we would experiment with the data on my lapoc-server, all we do 
there, would be subject for a complicated transfere-process. I would 
need to dump the data from the lapoc-server to a SQL-File and then 
import this file on the sf-page. Not a big thing to do but one more 
thing to do and vacation is comming to take me away to the dark nebulas 
of off-line soon ;-)

So I hope it is not too great an offence to have this alpha-version on 
the sf-page. Anyway, nobody, who does not know the file-names will find 
it....

best regards

p.s.: this is, of course the first step to a little CMS for the website ;-)

Imagine an old-fashioned well pump with a long handle that is used to
pump the water. A single person can thus pump water from the well by
pulling the handle down, and pushing it back up again. This would be
comparable to a single-ended amplifier. 

Now imagine that a second handle is attached, pointing in the opposite
direction. Now two people can pump at the same time, effectively
doubling the amount of power applied to the pump. While one person is
pulling down on his handle, the other person is pushing up on his. The
electronic analogue to this situation is called - appropriately enough -
a "push-pull" amplifier.
http://www.dogstar.dantimax.dk/tubestuf/mnibl2-1.htm

and the feedback amp is :
An amplifier in which a passive network is used to return a portion of
the output signal to its input so as to change the performance
characteristics of the amplifier.

In the guitarix push pull amps both units are used, so first a feedback
pre amp followed by a push pull master amp section. 

In the new feedback amps, only the preamp section runs with two feedback
stages followed by a linear tube stage 3.

The pre/master amps are straight linear, 3 tube stages followed by a
master tube. 
The single tube amps are likely pre-amps only.

well, it's done. 
More over I have also add a new feedback mode for the single tube's.

I could add a push pull mode for the mixed tubes 
pre 12AU7/ master 6V6 and pre 12ax7/ master 6V6 but not for the "single"
tube modes, because I need the master 6V6 tubes for that.

very little cpu usage... like you said, only 2% more...
will this be applied for all the tube settings?
really beefy tones when you play with it... the postamp really has improved
also...

[Guitarix-developer] new push/pull tube mode

[hermann <bru...@we...>]

Hi 

Today I have add/finished the new push/pull tube mode witch is designed
to work best with high distortion. 
This unit include 7 tubes, there-from are 2 tubes in feedback and 2
tubes in push pull mode. All in one it need's a bit more CPU, here it's
2% more, but I think it is it worth. 

Also I have add a new gradient property to the GxPaintbox class,
box-gradient, witch allow to set the colour for the inner box from the
effects in the rack. So we get a bit better control for the skins in the
rc-files.
