From HW wise I think it is not possible what we see on the SID.
The internal circuit is not accessible, and the 3 channels are mixed together inside the SID, and there is one single audit output. So it is not possible to connect 3 scopes to the SID legs and show the channles separately.
As told, from a SW it is possible. In fct, not for the player. Creating the waveform graphical shape could be easy on Plus/4 (square), but even on +4 to faithfully draw noise, is a challnge. The SW itself knows, what frequencies used, and even some players capable to show some volume meters. (I do remember my Pentium I 133MHz had some troubles to show the frequency curves during mp3 playback, due to CPU limit)
What we saw on the video is most probably (as told before) is a modified emulator. It is really fun to see the major difference of triangle, square and other waveform VS digidrums. (I suppose they are not just simple noise waveforms)

gerliczer I would do so for sure if I had the skill. Unfortunately I have not ;-( Only BASIC skills...
Glad to ear Csabo! Do you mean the 1.2.4 version (I couldn't find anywhere) have the scope view? do you mean there is a prg or the windows version?
Granted Gaia's permission, would you share it?

Yes! This is such a good idea, isn't it  When I saw those videos a few years back, I asked Gaia (coder of YAPE + TedPlay) to implement it. He did add something similar, see here... ("visual waveplotter added") It doesn't look quite right, and when I mentioned it to him, the line of discussion just fizzled out. Now that I'm looking at TedPlay, I'm not sure where I got the latest EXE from :-/ But if you can get the latest (1.2.4, I think), you should be able to see it.

No, the plussy wouldn't. I don't want to misinform you, but IIRC Rolf's oscilloscope view is conjured up from data generated by a modified SID emulator. Obviously, emulators can be modified to do such a thing. TedPlay's source code is available. Be our guest to do it.

| Oscilloscope for TED?
I was wondering if it would be possible to implement in a TED player an oscilloscope to visualize the channels and the waveforms like Rolf R Bakke do on youtube.

Would be the plussy capable of this? I would guess so.
