Good news everyone!

I have been experimenting again:

hi, can you explain the principle of this type of sound? Mixture of two "curves"?

It's actually a mix of 4 oscillators, each 1 Hz away from the next, i.e. at 400, 401, 402 and 403 Hz.
They start beating because the peaks keep wandering relative to another. I also change the "waveform"
in between, i.e. the tone envelope representing high and low and each waveform is played at 3
different, increasing frequencies

Here's a great (albeit a bit long) video by the great guys at Khan Academy explaining the beating effect:
