One of my favorite things from my childhood was the PASCO FOURIER SYNTHESIZER which left me with a very deep and fundamental understanding of periodic waveforms and their Fourier series representations.
I was fortunate enough to be able to play on this apparatus back in the early 1970s.
Here I try to capture the ineffable sense of awe and wonder that it left upon me.
Also featured is the Eico460 cathode ray oscilloscope that I've had since childhood, modified by switching over to a transparent CRT so you can see inside it and understand how an oscillosocpe works.
In 1978 I composed a piece of music that contains only a single note (while its various harmonics gently rise and fall): Adagio for PASCO FOURIER SYNTHESIZER and Lock-in Amplifier.
In 2016 we (Splashtones) did a live performance of this piece, accompanied by hydraulophone and clarinet, as the headline act for VRTO 2016.
