A major error of “mishandling of global variables” placed in the LPF was discovered and corrected in the relevant section.

The variable that buffers the audio in the code that builds the LPF was shared among the outputs of Wavetable, resulting in a near-monaural sound output configuration, but the problem was solved by adding a local variable to the LPF subroutine.

While the unnatural distortion of the output sound has been eliminated, the filtering effect has become shallow, but we need to consider whether this can be corrected by setting parameters.

In addition, a change has been made to add a SceneMemory display item.
