Noise Generator has two manual controls: one for spectral balance (“color”) and one Noise Generator

for output level.

The spectral balance is continuously variable from white to red (low-frequency noise

output). In the latter case the output falls off at the rate of 6Db/Octave; the pink noise

position approximates a -3Db/Octave slope.

The level control, at minimum, cuts off the output signal completely. At maximum, the

output is clipped at 20vV P-P to produce binary, or two-valued, noise. Clipping begins

with the level control approximately half open. input.

Voltage Processors (VP)

The

Voltage Processors

are simple utility functions for mixing,

inverting, and shaping signals.

4.11.1

VP #1

has four signal inputs and one output. Two of the inputs have attenuators. The

output signal is the inverted sum of all four inputs.

The attenuator-governed inputs carry default connections from +10vV and from the

keyboard pitch-control. Opening the +10vV slider thus produces up to -10vV at the

processor output.

4.11.2

VP #2

has two signal inputs and one output. One of the inputs has an attenuator. The

output signal is the inverted sum of the two inputs.

The attenuator-governed input carries a default connection from -10vV, so that opening

the slider produces up to +10vV at the output.

Lag Processor is a low-pass  lter for processing control signals. The slider adjusts Lag Processor

its cutoff frequency. The corresponding rise-time ranges from 0.5ms with the slider at

minimum, to 500msec – about half a second – with the slider at maximum.

The

Lag Processor

can be used to process audio signals, as a -6Db/octave manual  lter

Lag Processor can be used to process audio signals, as a -6Db/octave manual  lter Lag Processor

with a maximum Fc of approximately 1KHz.
