hi everyone,

i'm trying to make a patch that moves steadily and continuously along a range of values back and forth from one extreme to another using line~. specifically i want to use this to move a 'panning knob' back and forth between 0.05 and 0.95, and also to move a modulation frequency slider on a simple FM synth back and forth.

any tips on how to do this without running into deep recursion/stack overflow? i've tried using combinations of [select] and [== ] but i keep getting stack overflows. i think i'm just using the wrong combination of control objects but i am sort of stumped. any help would be great thanks!

also sorry for not posting the patch itself, i'm on my work computer right now :-/

here's the patch, it's messy but hopefully you can see what i'm talking about

I'm not getting stack overflows with this patch, and I don't see any recursion here. I also see that you have some [sel] and [== ] objects, but they aren't really being used. I'm guessing you didn't attach the broken patch that tries to do what you want. I would suggest attaching that one instead, because right now...I can't tell what you are trying to do and how you are trying to do it.

oops sorry - i uploaded the wrong version. i'm attaching a cleaned up version with comments, hopefully now you can see what i'm talking about. thanks for the response!

Hey,
just conect a [print] to one of the [sel]'s...
Here is a hint: You are misusing the [line]...
Another one: What is [line]'s !immediate! output if you give a new ramp to it?!
Now it's your turn again..

If you know already how long [line] is going to ramp, you don't need to test it's output because you already know when it will get there. It would be much easier to control it with [metro].

Also, you don't need [line] at all. Using [line] to control [line~] is just redundant.

maelstorm thank you for the example! i see now how controlling line~ with line doesn't make sense

Flipp thanks the print thing shed a lot of light on the situation for me
