Hi, this is my first post on this forum. Sorry if I am asking about something that has been commented on before.
I tried to use the ADSR envelope in plugdata, but the release stage starts after the attack and decay stages are finished, which is not what I need Because of that, I decided to build my ADSR from scratch, and is working as I want. The only thing I don´t like is that the attack, decay and release stages are linear, directly from the vline object inside my custom subpatch.
How can I add a convex attack stage, and concave decay and release stages? Within my patch, all the different stages are launched with a single vline object. If I apply some exponential law, I am applying it to every stage, and that's not correct.
Could someone help me to find documentation for an ADSR patch where I can see how it has been built?. I tried to open the ADSR object in Plugdata, but it has not been possible.

Thanks very much for your help!!

@JuanMadrid Hello. You can use the [curve~] external, or if natural curves are sufficient then square the output of [vline~]......
See this thread....... https://forum.pdpatchrepo.info/topic/9819/curved-adsr-envelope/3

And yes... you cannot open that adsr object because it is not a patch. It is a compiled object like [vline~].

@JuanMadrid Maybe use a 2nd [vline~] to sequence the exponent? I think you might have to do something similar to adjust the transition to/from the sustain level.

What version of PlugData do you have?

If you have the last stable version 0.9.3 this is what you have and shows you how to set the envelope for immediate release or not

A new version of ELSE and plugdata is already up as part of an experimental 0.9.4 PlugData release and things changed a bit.

So there's nothing really wrong with the object, you just didn't check the help file carefully

this is what I have for the upcoming version, a more versatile and sophisticated time management system

I'm really sorry that I end up changing things a bit, but as long as PlugData is still at an experimental 0.x.x version I am doing this in favor of improving and enhancing the objects. When PlugData 1.0 is finally out (and I can't wait for Tim to do that), I made a pact with the devils that I should just stick to whatever bad decisions I had at the time and let it go...

Note that the new stuff I pointed above are already part of the experimental/nightly builds of PlugData.

As for designing envelopes, I have the "Live Electronics Tutorial", an extensive tutorial and all things ELSE and Pd, which is also distributed as part of the PlugData documentation. I have an example on how to build exponential envelopes over there, see

here's a screenshot you'll find in chapter 17

I also have added something like this to the help file of [slop~]

of course [else/adsr~] is much more powerful and offers more exponential curves. I find the one pole filter solution not that great, but I haven't bothered on trying to implement something like that in Vanilla

@porres Yes, you are right. I didn´t enter in the pd release patch to see the additional explanation. Thanks very much!

A lot of useful information here to explore and try during the next week.
Thanks very much!
Juan

it was historically immediate release by default, but in that particular version I was trying to accommodate more features and kinda screwed up... and now it'll be back immediate release with yet more features, so I was able to find a way to accommodate things.

It's hard to add features without breaking things.

By the way. I don't think [vline~] can be considered an envelope generator at all... you can do it, but it's a lot of hassle and it's only linear and very limited. For you to be able to deal with exponential curves and all the things I provide in my envelope generator is just virtually impossible with vanilla.
