Hey Ahmet,
I understand that you want to create a waveform that can be used to create a sound and use “scope” block to visualize the waveform.
You can use “Audio Oscillator” from the Simulink library, under Audio Toolbox->Sources->Audio Oscillator.
The Audio Toolbox provides functionality to generate tunable periodic waveforms for creating test signals, control signals, and your own unique sounds.
I am also sharing the link to the MathWorks documentation on ‘Audio Oscillator’, which provides examples for creating waveforms and generating melody: https://www.mathworks.com/help/audio/ref/audiooscillator-system-object.html
I hope this helps you in resolving the issue.
