Summary0010279: new_midi_track() does not work via lua script
DescriptionTesting some combinations of parameters never creates a new track, the scripting window always returns an error.

I was not able to map all the attempted parameter combinations. But I realized that even when entering the required types listed in the Binding Class Reference, there is always a type error in #6, #7, etc. And in some cases, while trying to figure out whether there is an error in the order of the parameters, Ardour simply crashes and closes.

Ardour 9.2 official build.
Steps To ReproduceOpen Window > Scripting.

Try something that looks like it:

function factory ()
    return function ()
        Session:new_midi_track(x,x,x,x,x,x,x,x,x)
    end
end

Search the example scripts. e.g.

https://github.com/Ardour/ardour/blob/master/share/scripts/_rgh_midi_track_trick.lua#L62-L69

  Session:new_midi_track(
    ARDOUR.ChanCount(ARDOUR.DataType ("midi"), 1),
    ARDOUR.ChanCount(ARDOUR.DataType ("midi"), 1),
    true,
    ARDOUR.PluginInfo(), nil,
    ARDOUR.RouteGroup(),
    1, "MIDI Track",
    ARDOUR.PresentationInfo.max_order, ARDOUR.TrackMode.Normal, true)

Sorry for opening a new issue. But I really couldn’t find this example anywhere. Now I’ve finally been able to adapt the script that creates the drum tracks to my case, where I make the drums in MIDI. Thank you very much.
