You could etch a tone wheel like one makes an etching or lithograph. Coat the disk with etching “tar” scratch in the waveforms then submerge it in acid. Then wash off the tar, the acid will have etched where the waveforms where scratched in and not where the tar was. There’s more modern was to make etchings with less harmful chemicals etc. I haven’t made an etching since the 90’s. The new techniques are friendlier. Man you could scratch in some wild waveforms. Maybe a wavetable type scenario. This is so cool. Such a perfect example of sound and art. I’m inspired.

I think the original question here is how it’s doing the envelope of each note, correct? I could hear that each note’s attack and decay was somewhat gradual. This video is the first time I’ve seen this type of tone generator, but my guess is that you’re charging/discharging the 400V to each etched waveform, and it probably goes through a resistor, so that the charge/discharge isn’t instantaneous. Just a guess.
