REQ: De-select last selected item

[daxliniere]

Hey guys, is it possible to write a script that de-selects the last selected item within an item selection across tracks, ignoring grouping?

Example, I'm editing multitrack drums. They are grouped (vertically) and occasionally I want to edit the position of just the first 1 or 2 items (kick drum mics).


A script that deselected the last selected item (shrinks selection) could be used in multiple instances in a custom action.

Alternatively, I'd be happy with a script that changes the selection of items to only the first 2 (or 1) items.


Any thoughts?
Cheers for reading!

All the best,

I suppose this could also be achieved through an adaption of SWS: Select Next Item (across tracks). That action selects the next item on the same track, rather than the next item on the track below.

Haha, it could also be done with an adaptation of the native action Item navigation: Select and move to item in next track without changing track selection

That action successfully selects the item below, but deselects the first selected item.

Okay, I think I've got it with a fairly convoluted custom action, but a dedicated script could be quite handy for other things.

Script: FnA_Unselect First Selected Item.lua
Script: FnA_Unselect Last Selected Item.lua

are now in ReaPack. Thanks X-Raym and cfillion for help!

Also:
Script: FnA_Ensure toggle ON (item grouping).lua
Script: FnA_Ensure toggle OFF (item grouping).lua

Woowoo!

Hello FnA. I'm trying to use your "Ensure toggle" scripts in midi editor, but I can't get them to do what I want.

View: toggle show velocity handles on notes (ID 40040)
View: toggle show velocity numbers on notes (ID 40632)

I want a Custom action that hide velocity handles and show velocity numbers. What I have done is:

I paste "40040" in your Ensure toggle off script, and rename it.
I paste "40632" in your Ensure toggle on script, and rename it.

I make a custom action with those two actions. The custom action does not work. And neither the new "ensure toggle" scripts individually.

Why?

[FnA]

Hm, that's a bit of a problem isn't it. That action was only meant for use in the Main Section of the Action List. Well, until I figure out what, if anything, to do for ReaPack, I'll make 2 examples here for use in the regular MIDI Editor. I don't see any toggle "state" being reported for any actions in the Inline MIDI Editor Action List, and I don't know how to trigger a Media Explorer action. So, regular MIDI editor only.

It requires a somewhat obscure integer to point to the other sections of the list. I had to be told about them by Jeffos, lol. And different functions too.

Fine, it works. I only need to operate in midi editor. Thanks a lot.
