At the end, because of performance blunders, I make a quick getaway in a flashy Honda 600cc sportbike ;-)

  • Very relaxing and strangely hypnotic. I really enjoyed this.

  • @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.

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

  • @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.

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

  • 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

  • @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?

  • hi

    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

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