After all this time reading about Buchla modules and the history of Don Buchla and his company Buchla&Associates there are still some modules I have never seen or heard of.
Like the Buchla Gating Matrix Model 312 from the Buchla 300.
Rick from The Electric Music Box posted the discription from the Buchla 300 brochure:
Used in conjunction with two model 292 quad lopass gates to implement digital
control over audio signal routing. Eight inputs and 8 outputs are provided; a
display matrix indicates status. Occupies one panel unit
I would put it in my rack just because it looks so beautiful.
