FLslider problem when saving inverse min and max

[santifer]

Hello,

I encountered a strange problem using the FLTK opcodes (look for "PROBLEM" in the pasted code below). It seems that saving snapshots doesn't work for sliders with min > max (in the reverse direction).

From the csound manual (http://www.csounds.com/manual/html/FLslider.html):

The imin argument may be greater than imax argument. This has the effect of “reversing” the object so the larger values are in the opposite direction. This also switches which end of the filled sliders is filled.

Am I doing something wrong or is this a bug?

Thanks

Santiago

Hello Santiago,

As far as I know, this feature is not supported. You can not save
presets of fltk sliders that are inverted. The support for fltk is
limited and I think that no further development will be made to the
opcodes either. They are in Csound for historical reasons, and for
providing a quick and dirty way of making a gui.

all best

I have noticed that also the following widgets

  FLslidBnk
  FLslidBnk2
  FLvslidBnk
  FLvslidBnk2
  FLknob
  FLroller
  FLtext
  FLjoy

can have imin > imax, therefore I have extended the change
and FLsavesnap now works with all these in "reversing" mode.

Thanks a lot, you guys are fast! I should get more involved in the mailing list. What do you recommend as the best way of adding GUI to csound instruments? Since I'm using the C++ API, I'm actually just thinking now of doing the GUI in Qt, the FLTK opcodes are great though for quick prototyping.

Best,

Santiago

I just realized that my question was too broad, I'll explain what I'm working on so you have a better idea about the type of GUI I need.

I am designing a drum machine with 4 voices. Each voice is assigned to a sample, amplitude and pitch envelopes and lfos, a low / high pass filter and the sample is played using flooper2. So basically... I need about 16 sliders controlling each voice (64 total).

I need a way to load 16 parameters at once in csound each time a specific MIDI note is played. So for example, If I press middle C, a specific sample is loaded and 16 k-rate and i-rate variables are set. If I later press another note, another sample is loaded along with different 16 parameters.

Then I want to save / load presets for each voice.

I guess I could create the 64 variables, 16 for each voice and just assign sliders to all of them, but then I'll just end up with a lot of variables and code... not very nice...

Any suggestions, comments?
Thanks

Santiago

CsoundQT is pretty good if you don't want to bother programming the
API. You can quite quickly develop pretty complex GUIs there.  I use
the Juce C++ library. It's pretty nice. It's provides good cross
platform MIDI and Audio IO classes so you can use Csound for the
processing only. On top of that you can use Juce to create lots of
plugin types. This is what Cabbage and Mike's CsoundVST do. They get
VSTs to call Csound through the API. Anything you write with Juce that
is a standalone instrument can pretty quickly be turned into a plugin.
Apart from that I've had good experiences with wxWidgets. I found it
really quite easy to use with lots of useful GUI classes. I've not
used QT but obviously it's a pretty extensive toolkit too.

Hi Rory,

Juce looks wonderful! I cannot believe I haven't seen it before. Do you use a designer to create the GUI in Juce? or do you code the GUI? I personally like to code GUI but it seems that using a designer is a better approach. Thanks for your informative email.

Best,

Santiago

[Michael Gogins-2]

I am experimenting with using Qt and C++ directly to create
compositions. I am changing some things about the CsoundAC MusicModel
class to enable it to run Csound in a separate thread so the GUI
remains responsive. I will make this available when it works and
demonstrates what I am trying to do. CsoundQt is great, but it is
possible to do larger and more complex GUIs directly in Qt.

For you CsoundQt developers, I personally would find CsoundQt more
useful if it had some sort of multiple tab control or multiple window
facility. This would actually make a big difference.

I've decided I need some GUI widgets to control Csound at least for
tweaking instrument pans, positions, and for mastering (compression,
reverb, EQ), and possibly for tweaking some instrument parameters. It
may take me a while to figure out just what is the best way for me
personally to work, or I may use one approach for some pieces and
another approach for other pieces.

Regards
Mike

I rather hand code my GUIs too. GUI designers are nice but I find they
can be slower in the long run.

In CsoundQt (compiled with pythonqt support) it is possible to use a wrapper
to Qt classes  in python scripts or python cosole or even with python opcode s
within the csound code. include it like

from PythonQt.Qt import *

and you cna reach  all the power of Qt.

greetings,
tarmo

What you suggest would be a good suggestion for many people. However,
for me, for my algorithmic composition code, I need the speed of
LuaJIT or C++.

Mike

If I create the GUI in C++ Qt, how would you recommend I pass arguments back and forth? Right now I'm using the C++ API methods Csound::GetChannel(), Csound::SetChannel() and Csound::SetOutputValueCallback().

The problem with this is that I need to get/set each csound variable individually. Is there a way to get / set arrays of variables?

Thanks

There is a method to retrieve the full list of channels. Can't recall its name but you'll find it in  csound.h. It should help.

Thanks to all for your helpful advice, I have a better idea of what direction to take now.
