Lua: Adjust envelope points (values) via mousewheel

[daxliniere]

Can you explain the adj_sel_env parameter, please?

"adj_sel_env" is set to "true":

• Volume envelope has to be selected (by clicking on the envelope lane or an envelope point).
• This works better for the envelopes that are drawn over the media lane

"adj_sel_env" is set to "false":

• Volume envelope doesn't has to be selected.
• (Someone might prefer this setting: f.ex. when envelopes are displayed in separate envelope lanes.)

[daxliniere]

Thanks for that info. I'll check it out tomorrow.

(Specifically, I will check behaviour of selected points and simply points that are under the mousewheel.)

Cheers for your hard work, spk77, this is a really wonderful way to interact with envelopes.

[vanhaze]

This is really something, but i wish it could be used on all envelopes, not just volume envelopes.

Update:

• 2-Sep-2015: added support for all track envelopes
• Download from post#1 (second script there)

("local adj_sel_env" was set to "false" in this gif: Envelopes don't have to be selected - this works OK if envelopes are displayed in their own lanes)




Settings:

-------------------
-- User settings --
-------------------
-- Adjustment behavior
local adj_sel_env = false   -- true:  envelope has to be selected


-- Volume envelope step size
-- (User configurable "dB_steps": see "set_envelope_point" -function)

-- Pan envelope step size
local pan_env_step = 0.01 -- 200 steps (-1 to 1)

-- Width envelope step size
local width_env_step = 0.01 -- 200 steps (-1 to 1)

-- Mute envelope step size
local mute_env_step = 1 -- 2 steps (0 to 1)

----------------------------------------------------------------------

Will first script be updated with all envelopes?One more request (for first script if you wanna work on it) can it be mouse sensitive to envelope lane? so it only works (moves points) when mouse is in envelope lane (is that possible?)
.It would be cool if this could be incorporated into one mega script that does similar things (Envelopes/Item Volume/Track Volume)
Thank you very much for both scripts!

Thank you so much it is very useful, I feel now very comfortable with lanes.

Can I also ask for Adjust volume envelope point at mouse cursor via mousewheel (obey point selection), please?

i.e. When the adjusted point is part of a selection of points, all points within the selection should be adjusted.

Hello spk.

Forgive me if this has been added/solved already (and I haven't looked at the script -not had time to gen up on Lua yet), but Dax's issue with chasing the envelope point should be quite easy to deal with.

When the mousewheel is moved and the object under the mouse cursor is checked and found to be an envelope point, the mouse x&y co-ords, the envelope point ID and an envelope_point_lock flag need to be set. When the next mousewheel cycle is instantiated, this is repeated until the object under the mouse cursor is no-longer the original envelope point. If at this time the mouse cursor has not moved (or has moved only eg 1pixel from the stored position), then the script continues moving the original point until the mouse is moved, when the envelope_point_lock flag is reset and the point "released".

For multi-envelope lanes, this might be adapted so that if moving an envelope point exposes another envelope point, the original point remains locked until the mouse cursor is moved. Can Lua and the API detect which is the top envelope point in this case?


The "moving all selected points if target is selected" idea sounds useful too, but it would be good if this is only activated by a modifier, or can be defeated by a modifier.


I've missed the scripting crowd, I'm hoping that I'll have time this winter to join in again, to re-read my Lua book and jump in -I'm sure I can make my EEL scripts much easier and tighter in Lua -some things were so difficult without better arrays.

Best done as two separate scripts, that way the script doesn't have to try to discern modifier keys. It's just more programming work.

Hey PlanetNine, yes thanks, the current version works great.

That bit is easy Dax, done it a lot in EEL, uses same gfx function subset in Lua.

Ah, good, glad to hear it.

Hello planetnine,
That would probably work, but these script don't run in background (see "get_action_context" -function in the reascript help file).

EDIT: Have to test if "get/setextstate" would work here.

It's so much easier to handle strings, tables and arrays in Lua

I was trying this script this morning, on a selection of some adjacent envelope points , instead of just one envelope.

Maybe i miss(ed) something but this doesn't seem possible ?
If it's not possible, i would be my humble wish-for :0)


OSX 10.10.5 , Reaper 5.02pre3 - 64bit.

[daxliniere]

Do you mean the line? That would be great.

[vanhaze]

Hi !

Let me try to explain myself better:

- Make a marquee selection with the mouse, marqueeing 1) : just an envelope segment without
envelope points or 2): marqueeing a bunch of (adjacent) envelope points.

Then mouse wheel scroll over such a selection.

In case 1, 4 envelope points are created, to create the (horizontal) envelope segment.
In case 2, the selected envelope points will be highered or lowered equally, vertically, and keeping exactly their horizontal positions.

[mccrabney]

is there a hidden difficulty in making this apply to any selected envelope, rather than specifically track envelopes? i'd love to make this a default editing behavior for ALL envelopes, not just track envelopes. i'd even copy it into a 2nd instance and create a coarse and fine version, and alternate between them via shift+mousewheel / alt+shift+mousewheel.

[David Perry]

Edit: had a problem getting it to work the first time but tried deleting and reloading and it now works. Thanks!

[daxliniere]

Hey spk77,
Would it be possible for you to implement this behaviour, please?

When multiple points are selected, mousewheel over one of the selected points moves all selected points.
AND
Single (unselected) points can be mousewheeled too, even when a selection exists.

I think this went under the radar:

I would also like the first one to affect all envelopes, but seems like it wasn't updated. I think it's the more useful one anyway, as you can adjust multiple points at once. I managed to hack it though, by removing the

or envelope.name ~= "Volume" and envelope.name ~= "Volume (Pre-FX)"

conditionals, but I still gotta find out how to make the scaling only apply to volume envelopes.

[J Reverb]

This works on any selected envelope up/down/left/right with multiple points but the steps are fixed values using SWS/FNG actions.

Set up 2 custom actions

Shift+Mousewheel up/down
Action: Skip next action if CC parameter <0/mid
SWS/FNG: Move selected envelope points up
Action: Skip next action if CC parameter >0/mid
SWS/FNG: Move selected envelope points down

Ctrl+Shift+Mousewheel left/right
Action: Skip next action if CC parameter <0/mid
Item edit: Move items/envelope points right
Action: Skip next action if CC parameter >0/mid
Item edit: Move items/envelope points left

SPK would it be possible to enhance your script to support all envelope types and include left/right with step settings?

Same Question!

this is a cool script! (Thank You!)

it would be amazing if i could use it on any envelope point!

+1000...please !!

I don't know why I can't make this behaviour to work...

Every other point is going to opposite direction when multiple points are selected and the mouse wheel is rotated down (15s -> in the gif):

Haha, oh wow, there's definitely something bunk there!
Maybe you've found a bug in the way mousewheel data is passed from the host?

Maybe another scripter could take a quick look at it, then we can ask Team Cockos about it?


By the way, thanks for taking a look at this for me. I really appreciate it and think it will be a great improvement to the ergonomics of the original script.

[daxliniere]

And just to clarify, in your video you show adjustment of selected and unselected points, but you don't show if selected points are left untouched when adjusting unselected envelope points.

[lowellben]

Wish this was native Reaper, thank you for helping us with this script!

[daxliniere]

Can another scripter please check out mpl's script and confirm there's nothing he's missed? Then I will report it to Cockos as a bug.


Cheers!

Could it be that it does not work anymore on reaper 6? when scrolling on the points it sets the value to -inf.

Seems to work for me...I guess it needs the latest SWS beta: http://www.sws-extension.org/download/pre-release/

Yep, that solved it. Thanks!

[WyattRice]

Does this action still work?
I have latest Reaper 6.12c installed, and latest sws extensions.
I can't seem to make it work.
Thanks in advance,
Wyatt

Edit: Never mind. I got it working.
I forgot to assign a mod key + mouse wheel.

[WyattRice]

Could something like this be used to control TCP faders too?

How to edit a script to make horizontal mousewheel work in "reversed" direction?
