[LOGGED] Envelope Generator Loop Function

Many years ago the Envelope Generator was able to loop back from an end trigger.

 Whaaaaaa? Backwards you mean?

 HI @Mark,

Thats interesting but, I didn't mean the generator running backwards backwards. But does this patch help to explain? Beta version.channel level catcher.izz

Are you referring to the execution order of the inputs here? I.e., the fact that the trigger is above the values, so you need a trigger delay to the 'trigger' input to ensure the values are recognized before the envelope starts?

I don’t know why it is hard to articulate, but let me give it a go....

Let’s think of a scenario where we want to use a an Envelope Generator as an interactive fader for a series of level changes in the range 1-255.

In this example the default two value inputs of the Envelope Generator  are used : value 0 and value 1. The value 0 is initialised at 0 and the value 1 has the first level value we want to arrive at for the first fade event. At the end of each fade event the most recent end value needs to be returned as a value to the value 0 input of the Envelope generator. A new value 1 amount can then be set ready to trigger and a smooth continuity between output levels can be attained. 

First fade event:

Value 0: 0

Value 1: 127

Second fade event:

Value 0: 127

Value 1: 200

Third fade event:

Value 0: 200

Value 1: 50

And so on....

Using the end trigger of the Envelope Generator to directly action the loop parsing of the most recent end value to the value 0 input to become the start value ready for the next fade event action would reduce the necessity of using other actors (like the broadcaster and listener actors demonstrated in my previous post).

Kind Regards

if I really understand what you want you can make it with less actors and use a macro or user actor to repeat it. But you know it.I don't understand either why we need a loop or do you mean the possibility to conect the output  directly with the value 0 or value 1 ?

 Thanks for your advice, that’s helpful.

If I get this right - isn't a 'Value Delay Line' the most simple solution?

 Ah yes, that is a good solution thanks for sharing!

I’m sorry I didn’t realize there were so many replies to this feature request from so long ago. But this really was a simple request to have the envelope generator reach the end of its envelope and then restart right away in a loop. I have to insert a delay between the end trigger and the start trigger otherwise it fails. It really is a “simple” request (but maybe not “easy” to program into the actor?)

 This is due to Isadora automatically limiting feedback loops. This feature helps with stability and performance, especially during the build process where 'bad' loops might be introduced while experimenting. A delay of 0.001 wont effect the timing of the patch running, but it will tell Isadora that the loop is being managed.

@dusx thanks. I guess I'll just make a user actor then.
