How to delete all empty tracks?

[acintya]

How to delete all empty tracks (the ones which have no vsts on the chain and are totally empty)?

i found something but i dont know how i setup this?

https://stash.reaper.fm/v/25407/Delet...s.ReaperKeyMap


please help

The ReaperKeyMap file you found binds an action called "Xenakios/SWS: Select tracks with no items" from the SWS extension to a keyboard key. To use it, click on the "Import/Export" button in the Action List. It doesn't actually delete anything or check if there are any FX on the tracks, though.

Here's a short lua script I just wrote which deletes every empty (no items, no FXs, no envelopes) unarmed tracks found in the project:

-- delete_empty_tracks.lua v0.1 by Christian Fillion (cfillion)

reaper.PreventUIRefresh(1)
reaper.Undo_BeginBlock()

local track_index, track_count = 0, reaper.CountTracks()
local bucket, bucket_index = {}, 0

while track_index < track_count do
  local track = reaper.GetTrack(0, track_index)

  local fx_count   = reaper.TrackFX_GetCount(track)
  local item_count = reaper.CountTrackMediaItems(track)
  local env_count  = reaper.CountTrackEnvelopes(track)
  local depth      = reaper.GetMediaTrackInfo_Value(track, "I_FOLDERDEPTH")
  local is_armed   = reaper.GetMediaTrackInfo_Value(track, "I_RECARM")

  if fx_count + item_count + env_count + math.max(depth, 0) + is_armed == 0 then
    bucket[bucket_index] = track
    bucket_index = bucket_index + 1
  end

  track_index = track_index + 1
end

if bucket_index > 0 then
  local dialog_btn = reaper.ShowMessageBox(
    string.format("Delete %d empty tracks?", bucket_index),
    "Confirmation", 1
  )

  if dialog_btn == 1 then
    local track_index = 0

    while track_index < bucket_index do
      reaper.DeleteTrack(bucket[track_index])
      track_index = track_index + 1
    end
  end
end

reaper.Undo_EndBlock("Delete Empty Tracks", 1)
reaper.PreventUIRefresh(-1)

Save this this in a .lua file and import it in REAPER's Action List (click on the "Load" button right to "ReaScript"). You will see it appear in the list. Double-click on it to execute the script (you can also bind a keyboard shortcut to it if you want).

Thanks, you have some skills. It works. this is very useful for large experiment projects with more than 150 tracks

fast cleanup.

one offtopic question:

why does this SWS command work anymore in the new reapers?

SWS/S&M: Close all floating FX windows

SWS/S&M: Close all floating FX windows, except focused one

when you have 10 vts open this is really helpful, so that you can minimize all VSTs just with one shortcut/button and you have a clean arranger windows view.... but it does not work anymore

why?

They works for me here on REAPER v5.1pre1c with SWS v2.8.1, at least on OS X. If you think there's a bug, you should report it on their issue tracker or maybe here.

hmmmm, thanks.. but it is not that. i figured out now whats the problem ---- it works in reaper 32bit but in reaper 64 you cannot close bridged floating windows (vsts)

any ideas?

Thanks for sharing this code! Super helpful for me

Made one addition to the .lua script that accounts for sends/receives, it was deleting buss tracks along with empty tracks before.

Here's the updated code:

-- delete_empty_tracks.lua v0.1 by Christian Fillion (cfillion)

reaper.PreventUIRefresh(1)
reaper.Undo_BeginBlock()

local track_index, track_count = 0, reaper.CountTracks()
local bucket, bucket_index = {}, 0

while track_index < track_count do
  local track = reaper.GetTrack(0, track_index)

  local fx_count   = reaper.TrackFX_GetCount(track)
  local item_count = reaper.CountTrackMediaItems(track)
  local env_count  = reaper.CountTrackEnvelopes(track)
  local depth      = reaper.GetMediaTrackInfo_Value(track, "I_FOLDERDEPTH")
  local is_armed   = reaper.GetMediaTrackInfo_Value(track, "I_RECARM")
  local sends      = reaper.GetTrackNumSends(track, 0)
  local receives   = reaper.GetTrackNumSends(track, -1)


  if fx_count + item_count + env_count + math.max(depth, 0) + is_armed + sends + receives == 0 then
    bucket[bucket_index] = track
    bucket_index = bucket_index + 1
  end

  track_index = track_index + 1
end

if bucket_index > 0 then
  local dialog_btn = reaper.ShowMessageBox(
    string.format("Delete %d empty tracks?", bucket_index),
    "Confirmation", 1
  )

  if dialog_btn == 1 then
    local track_index = 0

    while track_index < bucket_index do
      reaper.DeleteTrack(bucket[track_index])
      track_index = track_index + 1
    end
  end
end

reaper.Undo_EndBlock("Delete Empty Tracks", 1)
reaper.PreventUIRefresh(-1)

That's great! Is there a way to tweak it into bypassing the confirmation prompt?

Thanks,

That was fast. Works great thank you!

This script is super useful, thank you!!

I think it should be included in Reapack.
There is one but this one does a better job

[cfillion]

Thanks, I've uploaded it to ReaPack as "Remove empty tracks".
