Listen through container's FX chain in Edit state

[AZpercussion]

Very often in sound-design projects I place fx chain on items. Moreoften on glued items.
And all the time it was a pain to propagate fx on multiply items, or store edited group of the items to reglue and place fx on new version.

For now Superglue gives excellent ability to non-destructive put fx on items as on whole one, or make nested fx-ed items.
Also it saves fx chain! Cool! But I can't listen changes through fx while container unglued.

It would be great if script will check is fx chain on the container item take. And if so, it would create children track with the fx chain and place items there.
On glue process it just remove unnecessary children track and move it's fx to container take.

Also it should be for Explode too, I think, cause remove fx chain is easier, than exclude from pool, especially when you work mostly without pooled containers.

Interesting idea. I can see the use case. The UX implementation might be quite difficult however, especially considering multichannel use cases. For example, how could this work with media lanes? Unfortunately Reaper still has hard-coded routing limitations (unlike a DAW like Samplitude) that preclude routing items to other tracks freely.

I guess the restored items could be moved automatically to a child track as you say at the time of Unglue... and of course the superitem fx chain would need to be saved at the start of the Unglue actioin as well, since during the Unglue all the superitem settings are only available as a state chunk.

I think, multichannel could work based on container's channel number. Or maybe moved to track fx can increase track channel count.

Saying about fixed lanes... I found several bugs. If they are will fixed, I hope, there will no problem to implement child track approach.
I'll mail you bugs some later.

I tried to make a function that should place before Unglue. The similar will for the after.
There is some troubles with moving FX, but it will be solved somehow. (Solved!)

`function BeforeUnglue(wantFL)
local container = reaper.GetSelectedMediaItem(0,0)
local contTrack = reaper.GetMediaItemTrack(container)
local contTrackIDX
local newTrack

for i=0, reaper.CountTracks( 0 ) -1 do
local testTrack = reaper.GetTrack(0,i)
if testTrack == contTrack then
contTrackIDX = i
break
end
end

if contTrackIDX then
reaper.InsertTrackAtIndex( contTrackIDX+1, false )
newTrack = reaper.GetTrack(0,contTrackIDX+1)
--reaper.SetTrackSelected(newTrack, true)
reaper.SetMediaTrackInfo_Value( newTrack, "I_FOLDERDEPTH", -1 ) --Set child
reaper.SetMediaTrackInfo_Value( contTrack, "I_FOLDERDEPTH", 1 ) --Set parent
if wantFL then reaper.SetMediaTrackInfo_Value( newTrack, "I_FREEMODE", wantFL ) end
--^^Set normal, fixed lanes or FIP mode

----Now move FX---
local conTake = reaper.GetActiveTake(container)
for i=0, reaper.TakeFX_GetCount( conTake ) -1 do
  reaper.TakeFX_CopyToTrack( conTake, 0, newTrack, i, true )
end

---Now move container to child track----
reaper.MoveMediaItemToTrack( container, newTrack )

end
end

reaper.Undo_BeginBlock2(0)
BeforeUnglue()
reaper.UpdateArrange()
reaper.Undo_EndBlock2(0,"test befor unglue",-1)`

Ah! I recognized what I missed. It's just zero instead of index.
reaper.TakeFX_CopyToTrack( conTake, 0, newTrack, i, true )
Updated!

This is a terrific idea, thanks for the code! Adding card
