LFO tool for MIDI editor and envelopes

LFO tool has nothing with AI, really, so no, it cannot be integrated in the same way the native LFO tool in AI properties is.


However, you can add your own formulas for waveforms in the script, if you're so inclined.

Hi!

Small graphical bug: if points order is changed, you need to add a new point to refresh the line:



Also, what could be nice is a way to prevent this changing order in a first place (like in reaper envelopes lanes) :P

(Not: I just realized the graphical is not just graphical: adding a new points refresh the envelope lane as well, so maybe the solution to prevent points order modifications is better)

Thanks again for this tool !

I have uploaded new versions to ReaScript. Please let me know if there are any remaining ordering issues.

@juliansader
All good Thanks !

im feeling stupidi cant seem to find this in reapack,only the midi version,i would love to try the envelope version?

[EvilDragon]

Look for Envelope LFO generator and shaper.

[SubbaseDnB]

again a dumb question,can someone explain to me how i use this to automate say a reaeq in the envelope version?

[EvilDragon]

LFO only generates data for the automation lane, so you first need to open up an envelope for the parameter you want to automate. RTFM

Hey Jullian!

Amazing tool I'm using every day!
Thanks so much for that.

I have a suggestion/request:

For now the script is working in an absolute way. I mean by that, if you already draw a curve for an envelope by hand and then trying to adjust the center first node for exemple, it didn't work as expected because it replace the older curve by the one corresponding to the script parameters.
Logical but not so handy.

What if the thing is relative?

I mean, the parameter are applied on the current envelope.
It would be AWESOME.

I know it's a profond change in the code so I'm ready for your reply!
;-)

Cheers

Hi, first time trying the script. While the script it's open -midi version create cc's- the midi track stops producing sound when i press play. Is that how it's supposed to work? i had to close the script to listen what i have done?

Edit:
The existing cc's version does the same, i can't hear anything while the scripts are open.

[juliansader]

Thanks for letting me know.

I have uploaded v2.50 of all six LFO scripts, which should fix the problem (hopefully I didn't break anything else).

[Pasajeromoronmoreno]

Thanks Julian!! Did a quick a test, and seems to work now!! I'm gonna test it better tonight, now i'm just leaving.

New morphing feature for the MIDI editor version, when applied to existing events:

[hopi]

another big WOW MOM for you Julian!.... what a kewl tool

ya think the morph will eventually get added to the normal env. version?

[_Stevie_]

Seriously... insane!!! *applauds*

[Vagelis]

Wow this is an amazing tool thank you!Is it possible to add a swing function in future updates?

Hi juliansader,

I have to say your tool is just awesome. The concept behind, the visual implementation and the handling are stunning. Many thanks for that.

One thing I would like to suggest - as this could add a huge amount of flexibility for on/off effects - it would be great to have a pulse width adjustment for the square wave. I know you offer the possibility to add own LFO shapes to the script, but when I saw it needs scripting functions etc. it just stopped my enthusiasm. (Have no idea how to do something like that.)

Anyway. Your script is great. And if its to complicated or to special to add a pulse width adjustment it will still be one of the best additions for Reaper.

Thank you!
Eli

[EvilDragon]

Agreed, pulsewidth would be really nice to have

[juliansader]

Do I understand correctly that you are referring to asymmetrical LFO shapes, with "up/on" parts longer or shorter than the "down/off" parts? (I.e. a "duty cycle" different from 50%.)

If so, do you intend to vary the ratio, or would a fixed ratio between on time and off time be sufficient?

[EvilDragon]

Yes, duty cycle. Currently it's 50%, square wave. It should be variable, possibly with the same way you adjust rate, center and amplitube curves.

Sounds like a lot of work for just one waveform, though... But you could do a similar thing for, say, sine (add positive/negative skew) or saw (morph it from rising saw to triangle to falling saw), etc...

[Eliseat]

juliansader,

my intention was only a pulse width adjustment. To use a slider which then widens or narrows the pulse wave like 10% up and 90 % down or inverted. Of course it would be great to have a seamless changing mechanism to automate from short "on"s to short "off"s. This would be amazing and a great addition as it covers part of the LFO wave requests.

I have no idea if this could be done with every wave form like EvilDragon mentioned. But this would - of course - make the possibility endless. Your tool is probably the most useful addition to Reaper. So its just great as it is. But ...



Greetings

Nice tool but I found a bug with LFO tool velocity.
Select notes
Transpose notes
adjust a LFO tool parameter
result : the notes are transposed back to initial position.

Coming soon:


[EDIT: New GIF showing multiple waveforms.]

[EvilDragon]

That's brutally awesome, Julian! Can you show what it does to other factory waveforms?

[lunker]

Fantastic! I love these tools.

Looks very promising. Seems like you take this serious.

Many thanks

[Vagelis]

Huge thanks!!Just what i needed ,lots of possibilities!

I had a crash to desktop with Reaper today.
I try to find the culprit.
Crash happened after I use LFO tool velocity in the midi editor.
Is LFO tool known for crashing Reaper ?

This is actually intentional: while the script is running, it will prevent changes to the MIDI, to prevent confusing the script.

I myself have never encountered crashes due to the LFO Tool, nor have anyone else reported such problem. However, if you find any bugs, please let me know!

I have updated the GIF with some other waveforms.

I have also uploaded the new version to ReaPack -- please let me know if everything works OK.

* Swing: Swing is calculated relative to the start of the time selection or Automation Item -- not the first phase step -- to ensure that the LFO remains aligned with the Rate/grid, even when Swing varies. This means that, if extreme Swing is used, the Phase step slider won't scroll smoothly any more. (But may result in some interesting new waveforms). In the case of square shapes, try phase steps of 25 or 75.

* Recall AI curves: When working in Automation Items, the script will try to automatically recall the last-used curve, when you re-select a previously used AI. This feature uses AI IDs, so isn't completely reliable and doesn't work when the AI's ID changes, but it is probably the best we can do at the moment. (FR: "Item notes" for automation items.) To reactivate the script and load the AI curve after working the arrange view, just click on any of the GUI elements.

[EvilDragon]

Game changer, Julian! Awesome!


(MIDI CC LFO version coming as well, perhaps?)

[dupont]

@julienasader

Reaper crashes afterwards.
I think transpire free transient plugin was the culprit but I can't see it in the crash log.

After a brief test I'm very impressed. This is really stunning. Though for a moment I thought the square wouldn't shift in both directions until I realized it is phase dependent. That's logical and very clever made. Everything feels smooth and fit. And I will make some further tests tomorrow in the break time.

Amazing! Many thanks.

[dupont]

Is it normal the automation starts to dance on the rythm of the track after a few secondes ?
Joking apart, that's a great usefull script.

When I select an AI, It recalls the last used curve but not the last used curve for the selected AI.

Whoops, there was indeed a silly bug -- thanks for letting me know! I uploaded v2.01 that should fix it.

You're welcome.
I tried V2.01 this morning and it works fine.
Thanks for your work.

[dupont]

I noticed, when I reset the LFO, the curve shape is not reset, is it intended ?
If I remember in previous version, reset set the curve to sine.

[juliansader]

I uploaded v2.02 with improved reset behavior, and a few other small improvements when using AIs.
