I'm working on a vocoded theremin, and I'm trying to get it running in a gallery. It will run fine for a bit, but then two windows will go blank -- namely, the one with the main vocoder and theremin bits of code, also incidentally the ones that have movement on them in sliders showing volume and theremin input levels. The vocoder one will sometimes glitch with the volume sliders kinda showing up, but will mostly be blank.

When I restart the program it works fine for a bit, but then it goes blank again a while later (unsure on exact timing).

The theremin uses an ultrasonic distance sensor through arduino. The mic is running from a blue snowball mic. Computer is off wifi, recent and updated mac desktop.

It seems like this is a glitch in Pure Data itself, but I'm not sure. Does anyone know why this happens and how to stop it? Or maybe what to do when it happens besides restarting the whole program? Really want to get this working smoothly.

Thanks,
-Joseph

Windows freezing... or updates to the window juddering.... is usually because Pd does not have the time to do the updates between audio blocks when there is too much screen drawing to be done.
That can cause audio dropouts too.

Disappearing GUI's or the window becoming blank I have never seen.
Impossible to diagnose without your actual patches.

If you are time constrained and desperate then hide (minimise) those windows and if the patch stays running smoothly at least your project will be working.
