I'm thinking of having an old-fashioned analog device made for teaching purposes. It would have a single loudspeaker and about 8 oscillators each with adjustable frequency and amplitudes (making, say, 16 knobs on the panel) and a master volume so the whole thing can be turned up and down. The idea it to easily demonstrate things like beats, roughness, masking, fusion of spectral components into complex tones, pitch effects and so on in lectures and labs, and have the students play with the machine themselves to get a feel for how things really work in complex tones. I prefer this approach to computer software because I couldn't be bothered setting up the right kid of computer and peripherals in various locations. And in any case I think the chunky portable analog approach might have pedagogical advantages. So my question is: Do other people want, or already have, similar devices?
