Crash when realising sequential Sines controlled by Lines

[ali1234]

Code:

if __name__ == '__main__':
    x = Sine(Line(220, 440, 1e3)) | Sine(Line(440, 220, 1e3))
    x.play()

Trace:

Thanks for finding this!

I found the problem, but I still need to decide on the most efficient way to prevent it.

In the meanwhile, here is a more natural way to accomplish this:

if __name__ == '__main__':
    x = Sine(Line(220, 440, 1e3) | Line(440, 220, 1e3))
    x.play()
