I just started using Ctrlr In AvLinux. At first
it said i need libc6 I updated it to Libc6-i686 to 2.17-5
then loaded. I built a mixer map for my vm-3100 mixer but it crashed
acouple of times Crah log follows:

________________________
Im using kernel 3.9.2

I Have alot of questions.
Here’s one can I use gifs in the program? I know that that by changing the
.gif to .png you can trick some apps into using it and get the animation to work. I tryed it as a back ground image but it diden’t work but
I really not know much of what im doing.

Does the Linux VST Version use the linuxVST.so format, or WIn.dll
How do I export the map to LinuxVST format.Do I have to learn Lua to Make a VST?

Can I use CC Multi mode and export it to a VST?

I’m a beginner at programming. please bare with me thanks
The mixer map does work in CC Mutli mode
Now i need to learn Sysex programming.

And Thaks for this great App

Can you be a bit more specific about your Linux distro (version, kernel, update level etc.)

How are you running Ctrlr (standalone/vst).

To answer your questions, yes you can export an instance of Ctrlr that will only hold your created panel (on any platform).

Yes you can use GIFs, i never had any problems with those (although i use PNG and JPG most of the time).

You don’t need to learn Lua to do a basic CC panels that communicates in both directions, you will have to use Lua if you want to do program dumps using SysEx (there is no universal way to do those)

Hi

Lets see this is AVLinux 6.0.1 32bit Using Squeeze packages, except the
packages from Sid to get Ctrlr to run. Kernel 3.9.2 custome built
by me. AMD 4/core Phemon 8meg mem
I run in stand alone now.
How do I start the VST interface? I really
want to be able to use these maps from inside Ardour 3 as plugins.

Does the Linux VST make a Native VST plug in?
Is their an Icon for Ctrlr

Thanks Jk

To start the VST you load the .so as a VST plugin, just like any other.

Does the Linux VST make a Native VST plug in?

Yes you start a normal Ctrlr-VST instance load your panel (or create it there) and export an instance, it exports a VST instance when in VST mode and a Standalone instance when in Standalone mode (it’s a copy of the started binary with some special properties).

There is an icon, in the sources there is a “Resources” directory and all the icons are there.

[atom]

Also i’d like to know when Ctrlr crashes, is it on start ? Are you doing something special ?

[J_Klitzke]

Hi atom

I hasent crashed in awile when im using the Program but when I Quit it
doent realy quick still shows up in the task manager and seems to be using alot of cpu then I kill it.

Im haveing a problem with sliders in linux ver (I havent tryed win ver)
Slider style = linearvertical
the box below the slider when you double clic it will take input
but after changing the background color it will no longer accept
input. The double cicked setting button has no effect. If i change
the color back to white still will not take input. The only way to correct it is to make a new slider and not change the color.

Update
I rebooted and started Ctrlr now the color issue is gone and im using
the 3.9.2 kernel ??????

So I tried running as a VST plugin, no go crashes Ardour3vst and Carla
plugin host as soon as I start it as a plugin

sh: line 1: 6328 Segmentation fault ./carla

JUCE Assertion failure in juce_PluginHostType.h:139
Segmentation fault ./ardourvst3

That all the out put it gives is ther any way to see whats going on
inside?

Do I need the VST SDK ? If so which one and where do i install it?

[atom]

To build Ctrlr-VST you need the VST SDK, version 2.4, the path to it is defined in Introjucer or the Makefile (the introjucer is a tool that mnagaes project the .jucer files in the Builds directory)

[msepsis]

Just my 2 cents, I also use avlinux (it’s excellent!) and just to be specific it is debian 6 “squeeze”. Atom, AFIK you do your linux builds from ubuntu 10.03. I know at some point in the past with previous avlinux builds I had a variety of issues running ctrlr that seemed to not occur when simply using the same distro atom used to make the builds — This is what I ended up doing as ctrlr was the main use for that system.

Yes ubuntu comes from debian but they are still very different in some areas which may lead to some compatibility issues that might show up in a variety of ways.

The latest binary build is actually latest Linux Mint 14.0 it’s also debian based, i went away form ubuntu cause they do too much stuff on their own.

[J_Klitzke]

Any ideas on the vst crash ?

Also I did install Mint15 Mate deb but when i run Ctrlr it
cant find GLIBC_2.15 which is in sid. So what is Mint15 based on
I thought it was deb testing which is Sid ? Need help

Can you give me help on what I need to do to get Ctrlr to run
as VST. Is the VST ver crashing because it cant find the vst sdk?
or should it open the editor window without it.

Before I Install Mint could you please tell what version your using any
libs that i need ?

[atom]

vst sdk is only needed to build Ctrlr it does not need to be on the system during Ctrlr runtime (it’s just a bunch of include files, no libraries or anything like that)

I’m not sure if the binary build on the web is Mint14 or Mint15, i’ll try and do a next nightly build soon and that one will be Mint15.

I found that the VST editor works in KX Studio with Qtractor
and Carla. So i started up the VST editor in Carla and started
working,got into it several hours thought I was saving but was’nt
I crashed for some reason when I restarted there was nothing saved
it also will not open example files in VST linux .The editor crashes
Ardour3 as soon as you try to load it. The stand alone editor seems to
work. But not the VST editor???

[atom]

I’ll try to test this on Linux. I couldn’t get ardour to run with VST (it needs to get rebuild and it has a lot of dependencies). But i’ll try a different host.

[atom]

I tried loading Ctrlr i Qtractor, but it won’t scan properly, qtractor does a VST call that’s not supported in the Juce/VST wrapper (at least that’s what it looks like in the console).

I tried loading it in the plugin host (example application from JUCE), but the GUI won’t show up properly.

From what i see there is a lot that’s wrong, but mostly in JUCE on Linux, i guess until this stuff doesn’t get fixed on the JUCE side i can’t really do a lot in Ctrlr.

[J_Klitzke]

Ha atom
The VST editor works in ver 0.5.0 of carla in KXstudio
the updated ver 0.8 crashes. the .5 ver is the one installed with KXstudio
i can live with that. Please tell me how to save my work as a vst.so
So that i can use to in Ardour and other vst apps in linux? I assume that once the map it saved or expoted to the proper format it can be loaded like
any vst plugin.

[atom]

You can’t export as “.so” from Ctrlr yet, i noticed i haven’t implemented the Native Linux stuff that’s needed to do that,

you need to export as .bpanelz for now or save as .panel files.

please remember that if you save your project in your host with Ctrlr as a VST plugin it will also save it’s state (at least it should, it does on MAC and WIN)

[J_Klitzke]

HI

Can I save my work in Linux and continue to work on it in the windows
vst editor and then save it as a vst.dll .Also work thats done in the stand alone editor can it be opened in the vst editor to continue work on it.

Are there any issues with the win7-64 vst editor?
