@metabog The inside face of the CRT is coated with a phosphor powder which glows when the electron beam hits it. It is designed to stay bright for a little while after as well, this helps for high frequency traces or when a large area needs to be drawn(TVs). That's also how you get that cool sweeping effect on radar/sonar displays.
@Phyle9 It's not what I mean, I obviously know that, it just looks like it draws exactly two waveforms at the same time, it's probably something related with refresh times where the previous trace fails to die out fast enough . I've never had an analog oscilloscope, so I've never seen this effect.
This is god from the analytical point of view, but music has a souls of its own and the soul if some that does not need devices to manifest itself.
The song won't be better before or after you analyzed it on the scope. But in the other hand is your purpose was to determine in what area of the frequency response is your guitar pick up behaving to replicate or enhance certain color, I guess the use of the scope is very practical. Other than that just a visual effect that is not contributing any
please:may i know how do You make every connection and things like that, as i would like to get my sound module(access Virus Ti) together with a midi controller keyboard connected to Your type of apparatus, oscilloscoping every sound module, so to say
ThankYou for Your information
Good bye
PS i compose music and love studying schoenberg's instructions
Very relaxing and strangely hypnotic. I really enjoyed this.

@metabog Yeah, probably because it refreshes every so many milliseconds... Pretty cool effect tho!

@metabog Because sound is a complex waveform and never a pure sinewave?

@metabog He's holding a bass note and playing melody so you are probably seeing the polyphony (two or more melodies at once)

Why does it look like multiple waveforms one on top of the the other?

A little bit of compression would give a little more 'constant' amplitude display too.
