As a complementation to 'saving enveloppes' a 'envelope generator' would be on top of my wishlist.

The basic idea is that you can generate clip envelopes with a LFO wave.
In this example there are 2 LFO's that can be 'mixed' (morphed) to generate more complex shapes. (A<-->B)..
LFO shape 'A' and 'B' can be chosen from a pre-defined list of shapes.
Each of the 2 LFO's can also be adjusted to 'Beat-mode' or 'Sync-mode' with their independed 'rates'....
Can you imagine how endless the possibilities/ combinations are?

I made a quick visualisation of how this can work and be implemented in Live:

In this example the LFO shape is generating an envelope for Operators' 'Filter Freq.'...

Yep, you are right.
I made a post sometime ago with clips containing LFO-generated controller curves in midi clips in Live (I used Plogue Bidule to send the CC's).
But then I noticed something strange: The speed for the control curve does not react to the speed setting for the clip! So if you have a nice LFO curve in the clip, the speed of the CC LFO control responds only to the BMP of the set. And I dont want to do one CC LFO for every thinkable speed!

BTW: Nice graphic work, wetting the appetite!

Well thats a real bummer..

I really like this kind of tweaking.. Its like working with hardware, patching cables; little modular touch...
It adds some randomness to your work, but still controllable because its syncable...
This feature would really enrich Live...

Abletons; what do you think? Worth some consideration?

You can find an example here:

I think that at least in unliked mode, the clip automation should have an independent bmp setting.

Exporting the clip with the CC curve and playing it in Plogue Bidule to yoke 4, receiving it in Live does give the chance to set it's speed.

Thanks.. very usefull..
I will try some CC curves with my Nord modular (that I didn't think of that before?) But still; an internal LFO generator would be very nice cause that one can be automated within Live..

With my proposal I think there should be 2 options/modes;
1. LFO generator as an 'ongoing' envelope modulator, not visible as curves in the envelope view.
2. An option to 'write' the envelope curve to the clips envelope view for further editing...

Oooh man, do I get exited by this idea...!

Yes - internal LFO would be fine, too.
That could be like the Simpler but outputting controller data - load the sine preset, the random, the pulse - ?

could you tell me what your set up is in Plogue Bidule? I'am trying right now but I don't get it done..
thanx

Check the tips and tricks section tomorrow. I will post a tutorial on how to set it up. Once you know how to set up one. You can setup as many as you like.

Cheers

First I made an LFO to CC Bidule layout and recorded the CC in a MIDI clip in LIVE.
Second I exported the MIDI clip from Live to a MIDI file and loaded that into a simple Bidule layout with just a midi file player and out via yoke to Live. (Could as well have recorded it in Bidule and saving it from there.)

I'm trying to upload the LFO layout but there seems to be some problems...

You seem to have a way to set up an lfo that is different from how i do it.
Have you tried it like this?

I've added an modulator to make a sine into a modulated sine etc.
You don't need the math for normalizing the +/- from the LFO by way of the param modulator?

Thanks, both of you..
I will try to generate some nice envelopes..
But still; give us an internal!

I just link the parameter modulator to the cc10 value slider. This will modulate the cc. the only math i need is a variable to determine the value of the cc.

What are you using math for? To sync it? or to modulate the modulation signal?

The little math, (x+1)/2, where x is the value from the LFO, is to normalize the values from -1 to 1 into 0 to 1, which is the range the CC wants it values. I'm lifting the LFO values so there will be no negatives.

If you control the amplitude of the lfo and see where at which amplitude it hits high and low. There really is no need for math. (at least in my case). Even if would want to limit it's output, i could do it with a value scaler. Because i'm controlling it from a midi controller anyway.
