Pause envelope generator
-
If using Envelope is not absolutely necessary(simple one step rising counter) you can use Movie Player. Trigger speed 0/1 to start and resume and position output for value needed. You just have to make a movie(or mp3) as long you need.
For more complex envelopes you can trigger with external timeline like Duration, QLab and others over OSC.I find Duration much easier to use than envelopes in Isadora. -
yep duration would be a good solution.
-
I still have to check out duration. saw the video yesterday and yes, it looks quite exciting.
Anyway, for certain purposes just a pause input in the envelope generator would do the job, while rising counters, movie players or even duration seem to be a lot of paraphernalia to simple pause the envelope.I will try out duration today. thanks for discussing!! -
You can just gate the output and keep the last value, put that as an input when you start it again right?
-
Fred, I had the same idea, but trying to build it got rather complicated. And when resuming the timing starts from the beginning. Like you run from 0-100 in 10sec, but resuming from 66-100 again 10sec instead of 3sec. So you need another counter/envelope to take care on that? While all you need is in Duration right there. 6511dc-stop-envelope.izz

Would not the relatively new Ease In-Out 2D Actor do the trick? It has the ability to Pause and Resume the action and can be done with a linear curve to match an envelope generator. Just set the curvature to 1.
Cheers,

you patch works beautifully, and yes, it is very complicated. I will study it in order to understand it, but I am pretty sure it gets even more complicated as soon as I want to use an envelope with 2 or more segments.[@cambrucedavis](http://troikatronix.com/troikatronixforum/profile/cambrucedavis)the pause input in Ease in-out 2D is exactly what I wish I have in envelope!! it is again not easy to work with this actor if have more than one segment. -
@camilozk
you can tether multiple Ease in-out 2D actors (using the 'complete' trigger to start the next one) as if each one were a segment. -
true. it is possible to draw a very complex envelope with multiple Ease in-out 2D actors, but then it gets again really complicated to pause the whole chain of Ease in-out 2D actors -
Hello,
I just discover the post and I also search a way to have an envelope working like the command on a lightning desk:– possibility to start/pause resume– possibility to accelerate/decelerate/go backwardEach time I give a class about Isadora, that is one of the first question when we make the first video player with automated fade, how to stop it? to go backward?I tried to do that with user actor using envelope, with duration, it can works, but not easy to use for begginers.It could be a great value to have that, easy to use in the tools, hello Mark and brave developers!jhoepffner -
this one will deal with the timing and resets itself after one pass -
Pretty clever
-
I make another proposition, with start/stop/resume/accel/decel/invert, it's a prototype, but show what I would find in a super envelope actor…
It's necessary to use the movie included (100 second 1 pixel movie). -
@m_theater hurra - this is genious - thanks for this idea - isadora life is going on
-
There's also Ease In-Out 2D which is like an envelope Generator.
Pros:
- Built-in curvature
- Pause, Resume, and Trigger inputs
- Can change two values at once (it says X and Y but you can use them for whatever)
Cons:
- Unlike an Envelope Generator, it can only have one "segment"
-
@woland - thanks a lot - this possibility is great too - however in my case i create a scene, where a satellite is circling round the moon - so I need four segments to let the object fly in a circle - I looped the envelopes by retriggering themselves - but then how can I stop the loop
- captured in the endless universe ! -
-
@michel - sorry for my delayed answer - the gate actor is perfect for stopping the whole process - but the envelope actor doesn't stop - so i found a solution with the pulse generator - i cannot stop and go whereever i want, but at least I can do that "behind the curtain"
- if anybody is interested how to control a satellite in universe
