Hello and welcome Javier,

Have you measured supply voltage at pin 14 of the 4093 and connection to ground/ minus on pin 7? Which 4093 do you use? Can you post a picture of your build? This makes troubleshooting easier for us.

Thanks for your reply. I fixed it. Just I would like to add a small effect to it. Could you to help me with it? It could be a different generator for example that does a kind of delay effect.
