Music technology was an expensive business back in the late 60s. It was very much the preserve of the rich or culturally successful elite, at least until a degree of democratisation occurred, during the early-to-mid-70s.
By 1970, companies such as Moog Music Inc. had distilled their mammoth modular systems down to Minimoog-sized proportions, but this was still an expensive proposition for most. However, the market was about to become far more competitive, driving the costs down to levels which, while still expensive, were more affordable.
