The Harmonic Synthesizer is an the lobby of the McLennan physics building, University of Toronto.
Here’s the description from the accompanying card:
This marvelous machine was used to dress the output of the large fork and resonator with a controlled set of overtones. Each fork is mounted in front of the appropriate resonator and driven by coils connected in series using the electronome interrupter tuned to the fundamental. A small keyboard opens the resonators.
It appears that the componenets of this apparatus have been redeployed, as the present set-up does not agree with the illustration in the 1889 catalogue and several pieces have been mounted with screws through the maker’s ark – an unlikely occurrence in the original mounting. This was probably done to allow operation of the keyboard from the back.
Would like to listen to it, though…
