The following demo shows a sawtooth wave being built out of 18 successive harmonics starting at 220Hz. The result is getting somewhat close to a sawtooth wave but 18 harmonics only gets to about 4KHz and it'd be better if more harmonics were included.

on the Telharmonium, including pictures of the original tonewheels.

The Kawai K5000 is the last major hardware additive synthesizer. It had three versions:
the performer-oriented K5000S with lots of knobs, the workstation-style K5000W which also had a built-in rompler,
and the (now quite valuable) rackmount K5000R. The K5000 created sounds using additive synthesis optionally augmented with transients, short PCM waves which provided an initial attack sound. But the bulk of the sound was additive.
