What's going on with the oscilloscope? I mean, why does it show square waves even though we can't even hear them? Even if the square waves were below human hearing, it'd at least be possible to hear the streamed sound be turned on and off at whatever frequency the wave is, but the sound is clean nonetheless. Sure there's a slight crackle sound effect but no amplitude modulation or gate effect, just a clean piano mod.
Great question! I wondered about this too. I /think/ that the two square waves are oppositely phased and I /think/ that sidwizplus which creates the video is trying to align the phases. In reality the channel pairs are at complete opposites, so the gaps of one fill in the gaps of the other. A comparable effect can be seen on DTA's previous mod player - ua-cam.com/video/hnv1bRCGJP8/v-deo.html - possibly the lower playback frequency of that mod player prevented sidwizplus from locking on to the wave forms quite as well. Does this make any sense?

@@StefanDrissenIt does. Thanks for the explanation!
It is SidWizPlus' trigger for aligning waveforms. I have uploaded a version with null triggers at ua-cam.com/video/q0zg1nQZKLw/v-deo.html
Happy xmas
