[sdiy] Buchla 257 is an extremely strange circuit

[Paul Perry]

A three channel mixer has the option of level control -
this 3 signal & 2 control system sacrifices that.
But, using a joystick for the 2 controls and a third
overall volume control would give a very practical
live performance 3 input mixer.
