blow that synthesizer!

Circuits for generating electronic music are usually controlled by key switches. Not only do keyboards offer the simplest technical solution for pro- ducing fast changing, reproducible tones over a wide frequency range, but they also enjoy tremendous R6 popularity because they are con- sidered to be easier to learn to play than string or wind instruments. Because of that, we have not tried to create an electronic oboe, flute, or clarinet with the present circuit. In any case, the technical intricacies associ- [)° CI 470n R1 3130 C3 100p 0 O 10071/0 15 V ated with such instruments would make their electrophonic counterpart prohibitively expensive. So, what we have got here is the rela- tively simple facility of converting breath power into a proportional analogue voltage with which the volume of a music synthesizer can be controlled; the tones remain con- trolled by the keyboard switches. No doubt, many of you, ingenious readers, will be able to think of various other applications...
