[sdiy] Re; David Tudor

[John L Marshall]

Recently there was a request for more information on David Tudor's boxes. 
Here is my guess as to what was used in "Toneburst":

Oscillators:
   Acoustic feedback
   Sawtooth
   Burst generator

Filters:
   LPF
   BPF
   HPF
   BPF, adjustable
   All pass filter, adjustable

Other Modifiers:
   Balanced modulator
   A+B, A-B stereo generator
   90 degree phase difference
   inverters

Mixers:
   6 channel stereo
   2x2 matrix
   4x6 matrix
   4x1
   2x1
   Joystick
   Segue

Note that none of the boxes appear to be voltage controlled. Lots of knob 
twiddling.

Take care,
John
