Thank you. That's exactly was I did.

But if I insert a plugin that was generated as described in QTractor, it starts with no preset + no effects each time.

I have experimentet with the -f parameter in the plugin-xml. It seems that saving state does not occur at all when used this way as a plugin.

Normally Guitarix saves state when the program is closed, maybe QTractor closes it by killing hard, so it cannot save state. I don't know.

If someone has a working setup, this would indicate that I am doing something wrong. Then I would investigate further.

Thanks,
Andreas

I just did test it here and it's working with Qtractor. The Plugin comes up with the old parameters.

The xml file looks like:

Code: Select all

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE CARLA-PRESET>
<CARLA-PRESET VERSION='2.0'>
  <Info>
   <Type>JACK</Type>
   <Name>guitarix_Right</Name>
   <Filename>guitarix -D -n Right</Filename>
   <Setup>220001</Setup>
  </Info>

  <Data>
   <Active>Yes</Active>
   <ControlChannel>1</ControlChannel>
   <Options>0x0</Options>
  </Data>
</CARLA-PRESET>

Interesting. My xml file looks exactly the same (it had the -f parameter in it, but I removed it to resemble yours).

It does not work. Guitarix starts with no preset. The effects are those that were present when guitarix was last started in standalone mode.

Could you please post me the exact version number of Carla, Guitarix and QTractor you are using?

Thanks,
Andreas

Hmm.. I tested if my own settings are recalled which is the case. When loading presets I get errors like the following in Qtractor and in Ardour. This didn't happen in the past.

Thank you.

I have carla 1.9.13, guitarix 0.37.3 and qtractor 0.9.3 with Qt 5.12.0.

So there might be a regression somewhere which leads to my problems.

I´m on arch, there is an older version of guitarix in the AUR, I will try that. The other packages are not that easy to downgrade.

Regards,
Andreas

Did you make a test with Ardour or any other DAW, e.g. Reaper?

No, not yet. I'll do that tomorrow.

I have a gig next friday, for that I need just one instance of guitarix anyway (for the bass guitar), because I will stick to my hardware guitar-simulation (good old line 6).

But in the long run I am very interested in switching to guitarix completely. The thought of saving all sounds of all guitars + basses + synths in one document is very attractive. But for that I need the plugin-functionality. One instance can be handled manually, but not several ones, I think.

Thank you for your patience!

Ok, I found a solution / a workaround / maybe an explanation.

I did not succeed in trying this with ardour. That's probably why I was using qtractor in the first place: I instantly got along with it, while I do not get the basics of ardour (I am a long-time cubase user, have started this on the Atari ST, so I am pretty much at loss when a program behaves significantly different).

In QTractor I get the plugin to save state by using "Quit" in the Engine-menu. Then, when the plugin is loaded next time, the state is as it was when quit was used.

Probably qtractor does not quit the guitarix-plugin gracefully, rather just kills it. Thus state is not saved automatically.

You need to go to Settings -> Configure Carla
In the Settings widget select Experimental, tick "Enable jack applications" and "Export single plugins to LV2"

Close the widget and the new shiny Add Jack application button will appear in the top bar.



I have done all the steps:
I've installed guitarix (no problems)
I've installed Carla
I've added the Carla vst to Reaper

BUT! I'm getting an error when I'm trying to add guitarix to Carla (see attachment for error message). I've followed all the tutorials and instructions in this thread, every correct box is ticked, but still getting the message. WHAT AM I DOING WRONG? It's driving me insane.

You may want to ask falktx about that over here:

The thing I'm more worried about then having LV2 and VST exported plugins in Carla would be being able to use automation in the DAW to control plugin parameters such as knobs and switches in plugins in the Carla rack. I get full access to Windows VST plugins with LinVst but not with Carla. One Synth, in particular, I would like to control the release knob via Ardour's audio automation and when I draw a line with LinVst it works, but there is no automation with Carla as a plugin :(( About Guitarix as a plugin just click add jack application, then right-click and "export as an LV2 Plugin". Another method is to use Gladish and click add application once it's started and type Guitarix.
