Open/close FX #-1 from last selected track

[nscotto]

Hi everyone!

First question here, I've finally passed the mental barrer of the the early steps in reaper and I'm getting into customization mode, seems like a whole new world is opening to me!

I didn't find in the action list a way to open/close FX from last selected track starting with indexing starting from the end of the FX chain (reverse order).
Can someone help me doing this?

Cheers!

PS: I am a coder so not afraid of writing a script for doing if that's the way to do it.

I'm not sure if this would help any, but SWS/S&M: Float previous FX (and close others) for selected tracks starts opening from the last FX in a chain and cycles backwards. SWS/S&M: Float next FX (and close others) for selected tracks does the opposite.

Welcome to the forums.

Thank you, that's perfect!

It was just for having shortcuts for opening meters on the master track, the meters are always att the end of the chain with evenutally some other FX before.
So to open the last one I just open the first and then the previous.
Neat!

Edit: mmmh... not exactly it. My custom action doesn't behave like a toggle, after I opened the plugin, if I trigger the action again it keeps cycling instead of closing the plugin...
Here is the action:
- SWS: Select master track
- Open/Close FX 1 for last selected track / SWS/S&M: Float FX 1 for selected track / SWS/S&M: Toggle Float FX1 1 for selected track
- SWS/S&M: Float previous FX (and close others) for selected tracks
- SWS: Unselect master track

It would be nice if I could access the plugin list in LUA and toggle the plugin UI from here, that would be the best solution IMO.

Ok, for toggling between different actions you would need to use SWS cycle actions. For that you need to have installed SWS Extensions, which is highly recommended.

With cycle actions you can not only build toggle actions, but also include e.g. conditions (IF, IF NOT). Some examples: https://forum.cockos.com/showpost.ph...postcount=1136

Now if you have the metering plugin as the last FX of the chain and you want to toggle that on/off, cycle action like this should work:
SWS/S&M: Float previous FX (and close others) for selected tracks
---step---
SWS/S&M: Close all floating FX windows for selected tracks


Even more is possible with scripts. For discussions about scripting, ReaScript, JSFX, REAPER Plug-in Extensions, Developer Forum would be a place to visit.

Couldn't make it with custom actions, as described it had side effects and didn't just toggle the windows I wanted... Didn't about the conditions though, that's cool!

Here's how it looks like:

For toggling the first FX from the end (change idx to 2 for second, etc.):
```
idx = 1

master_track = reaper.GetMasterTrack(0)
fx_count = reaper.TrackFX_GetCount(master_track)
fx = fx_count - idx

function toggle_fx(track, fx)
local toggle = not reaper.TrackFX_GetOpen(track, fx)
reaper.TrackFX_SetOpen(track, fx, toggle)
end

toggle_fx(master_track, fx)
```

Bonus, keep FX disabled and enable it when opening using the script (for saving some cpu):
```
idx = 1

master_track = reaper.GetMasterTrack(0)
fx_count = reaper.TrackFX_GetCount(master_track)
fx = fx_count - idx

function toggle_enable_open_fx(track, fx)
local toggle = not reaper.TrackFX_GetEnabled(track, fx)
reaper.TrackFX_SetEnabled(track, fx, toggle)
reaper.TrackFX_SetOpen(track, fx, toggle)
end

toggle_enable_open_fx(master_track, fx)
```
