The new and improved demonstration video has landed. There have also been content changes; different waveforms and octaves have been added, and the sawtooth waveform demo of scales was removed. Also the notes are now displayed on the screen along with the frequency analyser, oscilloscope displaying waveform, and oscilloscope displaying phase angles.

Video position description:

Introducing the concept of dissonance
0:00-1:24 - Sawtooth waveform
1:24-2:56 - Sine waveform

Scales - Sine waveform
2:56-3:17 - Equal temperament C4 + F4 + F3 + Octaves
3:17-3:38 - Pythagorean C4 + F4 + F3 + Octaves
3:38-3:58 - Equal temperament C4 + G4 + G3 + Octaves
3:58-4:20 - Pythagorean C4 + G4 + G3 + Octaves
4:20-5:02 - Alternations

Scales - Square waveform + distortion (harmonic emphasis)
5:02-5:25 - Equal temperament C4 + F4 + F3 + Octaves
5:25-5:45 - Pythagorean C4 + F4 + F3 + Octaves
5:45-6:05 - Equal temperament C4 + G4 + G3 + Octaves
6:05-6:28 - Pythagorean C4 + G4 + G3 + Octaves
6:28-7:21 - Alternations

Scales - Organ
7:21-7:43 - Equal temperament C4 + F4 + F3 + Octaves
7:43-8:04 - Pythagorean C4 + F4 + F3 + Octaves
8:04-8:25 - Equal temperament C4 + G4 + G3 + Octaves
8:25-8:46 - Pythagorean C4 + G4 + G3 + Octaves
8:46-9:24 - Alternations

Dissonance, Equal Temperament, And Pythagorean Scales - YouTube

Notes: The oscilloscopes are showing the clean square waveform with no distortion.
The spectrum analyser is on the output bus so the distorted square signal IS going through it so it's displaying all the harmonics, not the clean square waveform spectrum.
