Hello, I am a new user in Pd.

Currently, I have been studying Pd, but I have some questions.

When I try to change frequency of sine wave, there is some unexpected sound.

To remove the sound, would you give me the solution?

Additionally, to make an exponential line, I used [exponential_curve].

But if you have a better idea, please give me recommendation.

Thank you for reading my post.
