So i made a pretty simple module, a filter that an lfo can run into and it effects the cutoff frequency. For some reason when i run an lfo into it, it works for a few seconds then it crashes the audio on my computer as well as pure data. No audio will work, in pure data or otherwise until i close pure data, and even then it takes a few seconds to come back. After that, the audio is fine as long as i don't run the patch. Does anyone have any idea why this would be happening? I have attached the module so you can let me know if im doing something wrong.

doesn't seem to crash here.

but the meaningless banging of the knob externals should be avoided, as should the number boxes that are not part of the GUI.

also,
look into using [trigger] ( abbreviated as [t ] ) to sort out the issue of getting floats into the right side of [- ] before the left side.

and, for basic debugging, a good way to go, is to save a copy of your patch (with a different name, of course) and then just delete one part, save it, open it again and see how it goes. Eventually you will find the part that is causing trouble.
