      Do you want it to stop at an action from your side or lets say for example always stop at 7, 15 and 20 seconds?

        I want to be able to freeze its behaviour when I order it to, and to resume its behaviour when I order it to.

          Well in this case the only possibility is to "pause the engine" CMD+SHIFT+P, but then it pauses everything also the movie that is playing.

            There is probably a work around; maybe a trigger value actor a the end or something?

              thanks guys

              pausing the engine is not an option.
              perhaps there is a work around but I thought that could be much simpler.

                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.

                              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.

                                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 backward
                                    Each 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!

                                      this one will deal with the timing and resets itself after one pass

                                          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).
