About Lua scripts use

stratojaune · April 21, 2020, 9:18am

Can somebody please confirm that with the “script buttons” up right in Ardour6, one can do in one clic those kind of things:
"FOR THE SELECTIONNED TRACK(s): add PF a-comp + PF a-eq + AFsend to the bus named “RVB”+ route the ouput of the track to ONLY the bus named “GEN”

Or deed I completely misunderstood the tool?

Thanks

Yes you can script these kind of batch operations.
And you can also assign the script to a button.

Thanks Robin, when I will re-start Ardour to make music with it I will try to do that, so most of time will go to music!

For a head-start, see

github.com

Ardour/ardour/blob/master/share/scripts/_channelstrip.lua

ardour {
	["type"]    = "EditorAction",
	name        = "Channel Strip Setup",
	license     = "MIT",
	author      = "Ardour Team",
	description = [[Add Compressor and EQ plugin to every selected track and if a bus name 'Reverb' exists post-fader reverb send]]
}

function factory (params)
	return function ()
		-- helper functions
		function plugin_uri (proc)
			return proc:to_plugininsert():plugin(0):get_info().unique_id
		end
		function add_lv2_plugin (route, pluginname, position)
			local p = ARDOUR.LuaAPI.new_plugin (Session, pluginname, ARDOUR.PluginType.LV2, "")
			if not p:isnil () then
				route:add_processor_by_index (p, position, nil, true)
			end
		end

It doesn’t re-connect outputs, but that can be added, have a look at e.g. fan_out_instrument.lua script.

Many thanks, this will ease my workflow!

Thanks again Robin,

I have only changed the bus name in it and its name prefixed with “00-” to have it first in the list, and it works nice for all future sessions when saved in /opt/ardour/share/scripts/

My next step may be to really understand this language… Is it C++?
