A-149 /1

1. Introduction

Module A-149-1 is a Random Control Voltage

Source based on the idea of Don Buchla's "Source of

Uncertainty 265/266" modules. It has available 4 ana-

log random voltages, that are generated in different

ways.

The Quantized Random Voltages section has avai-

lable the outputs N+1 and 2

States. N is an integer

number in the range 1...6 that can be adjusted manu-

ally (Man N) and by an external control voltage CVN.

The voltage steps are 1/12 V for the 2

output (i.e.

semitone intervals) and 1.0 V for the N+1 output (i.e.

octave intervals).

The

Stored Random Voltages

section has available

an output with

even voltage distribution with 256

possible output states and another output with

ad-

justable voltage distribution probability. The distri-

bution of this output can be adjusted manually (Man D)

and by an external control voltage CVD. The voltage

range is 0...+5 V for both stored random outputs.

The rising edge of the corresponding Clock input

signal triggers a new random voltage value at the

outputs.

Each output is equipped with a LED that displays the

current output voltage.
