Script to select items in track xx

[ndchong]

Hi there,
Anyone can help me with a script to select items in tracks 3,4 and 5?
Thanks

Why particularly those tracks?

Anyhoo, there's a script (check out ReaPack ?)
Script: X-Raym_Add all items on selected track into item selection.lua

So just select the tracks you want (remembering you can do discontinuous selections)
and run it.

Thanks- that is what I was looking for.

I needed a one key push during live performance to select items on selected tracks and then pitch up 1 semi.

Thanks

Hmm still no go...

My custom action
Track Select track 3
Track Select track 4
Track Select track 5
Script: X-Raym_Add all items on selected track into item selection.lua
Track pitch up 1 semitone

But it only selects the last track which is 5.

I need to select track 3 4 and 5 all at the same time.

is this too slow?

Track Select track 3
Script: X-Raym_Add all items on selected track into item selection.lua
Track pitch up 1 semitone
Track Select track 4
Script: X-Raym_Add all items on selected track into item selection.lua
Track pitch up 1 semitone
Track Select track 5
Script: X-Raym_Add all items on selected track into item selection.lua
Track pitch up 1 semitone

there's also this action:

Item properties: Pitch item up one semitone

maybe try that in your original custom action instead of the track pitch?

Try this script:

local tracks_to_select = { 3, 4, 5 }

for i = 1, #tracks_to_select do
  local track = reaper.CSurf_TrackFromID( tracks_to_select[i], false )
  if not track then return reaper.defer(function() end) end
  tracks_to_select[i] = track
end

reaper.PreventUIRefresh( 1 )

reaper.SelectAllMediaItems( 0, false )

for i = 1, #tracks_to_select do
  for j = 0, reaper.CountTrackMediaItems( tracks_to_select[i] ) - 1 do
    reaper.SetMediaItemSelected( reaper.GetTrackMediaItem( tracks_to_select[i], j ), true )
  end
end

reaper.Main_OnCommand(40204, 0) -- Pitch item up one semitone


reaper.PreventUIRefresh( -1 )
reaper.UpdateArrange()
reaper.Undo_OnStateChange( "Pitch items up one semitone" )

Your custom action selects track 3, then selects 4 (deselecting 3), and so on.
babag has the answer (above). Although it's not necessary to add the track items into a selection, if you're using track pitch (as babag hints)

amagalma's script also does the trick. Configuring the tracks to select in a list
"local tracks_to_select = { 3, 4, 5 }"

This will be useful when you have a requirement to select some other track set. And you will.

Incidentally, why use "CSurf_TrackFromID" rather than reaper.GetTrack()?

I wonder what the use case is for this? Obv, we're transposing - Perhaps there's a better way to do whatever it is that you're trying to do?

No reason, it's the same. It could be:

track = reaper.GetTrack( 0, tracks_to_select[i] - 1)
