Load plugins on selected track with lua

Getting Stuff Done Lua Scripting
#1

Is it possible to load a plugin on the selected track by using a lua script? I tried to do this for some time now with deepseek but it’s not working. Unfortunately i am not a programmer. My goal was to get a bit closer to FX Racks by creating a script that loads, LSP Param EQ, ACE Compressor, LSP Clipper and Draggonfly Room Reverb with just one click. I use this combination a lot and it would save a lot of time for me to have a script for that.
Maybe someone allready has a script, that does similar things? :slight_smile:

I just found this. https://github.com/Ardour/ardour/blob/master/share/scripts/_channelstrip.lua
I am going to look into it and hope i can manage to get to the desired result.

Would a track template accomplish what you need? The Ardour Manual - Track Templates (I guess that doesn’t help with existing tracks.)

Good tip! Thanks! I am using track templates allready. But very often i decide to use this group of plugins later on.

#5

No help needed anymore! Thanks! I do not know how to close this. But i am at a state where i can manage to create the script i need. I will post it here if somebody needs something similar. :slight_smile:

Though you said “case closed”, to me it sounds as if saving mixer strips is what might help:

It is a new feature in 9, if i understand correct.

Same as with tracktemplates: This is helpfull regarding quickly reproducing the same setup used before. What i am looking for is being more flexible and adding the plugins later on in the process. But thanks! :slight_smile:

	ctx:set_source_rgba (ARDOUR.LuaAPI.color_to_rgba (fg))

	ctx:move_to (wl - fw, fl)
	ctx:line_to (wl + fw, fl)
	ctx:move_to (wc - fw, fc)
	ctx:line_to (wc + fw, fc)
	ctx:move_to (wr - fw, fr)
	ctx:line_to (wr + fw, fr)
	ctx:stroke ()
end end

This is what i am using now. if anybody finds use for this: Just look up the URI of your LV2 Plugins in the pluginmanager and switch it inside the script. :slight_smile:

Unfortunately this works only for LV2 so far. I have no clue how to add VST3 Plugins.

I would have searched in vain for this feature in Mixbus 32C v9.2 if it is only now included in Ardour v.9.
Is this function now also available in a newer Mixbus?
