CFR Associates,1977

[Paul Perry]

I notice an advertisement in radioElectronics (USA)
June 1977:
Audio& Music Synthesis Experimenters
since 1973 we've offered ideas, kits, plans & parts
CFR Associates Newton NH 03858

well naturally enquiring minds need to know more!

BTW, that issue has an article "build this electronic 
music box' by R.A.chamberlin using pink noise to select pitch
and duration of each note. called the Infinitune, selects
notes from 3 octaves of a pentatonic scale....

the kicker is, it uses LM3900s for the noise source,
over  a range of .05 to 100Hz. and you have to find ones
with enough ordinary noise, but not too much popcorn noise...
