[sdiy] Buchla 266 fluctuating voltages

[john mahoney]

Hiya, kids! I was on vacation for a week, in Toronto with the Missus. So,
there goes the neighborhood again. ;-)


Here is a web page with 2 audio samples of the MM5837:

Listen to the long sample and the looping should be obvious.

This is a textbook case of something that measures well but sounds like
crap! Look at the graph -- it shows a beautifully balanced frequency
spectrum. As Harry wrote, the chip is useful for some things but it's lousy
as a noise source for a synth.

The Korg Mono/Poly originally used the MM5837, but later models had analog
noise sources.
