Random Tone Generation Question

Hi!

While yes I know I’m totally out of my depth, I wanted to have a go generating a random sound that changed frequency every x seconds in a loop as a test for messing with the system.
So far I can generate a sound to start with, but having trouble figuring out how to trigger the reset to keep it looping as any attempt says “This connection would cause a loop” which is actually what I want ;p

Regards,
Lochy.

Update: Instead of deleting, decided to add update.
Shortly after submitting this, I was able to use the quick start guide to achieve what I was looking for. Now I’m researching how to create some basic sounds and learning about frequencies and harmonics of the different wave shapes.
