1 White Noise Out :
This is the White Noise Output and signal level is +/-5 Volts peak to peak. Pure white noise
is a sound that contains every frequency within the audio range (generally from 20 hertz
to 20 kHz) in equal amounts. This white noise is generated by using a specially selected
transistor in avalanche mode and using the exact circuitry from the Model D synthesiser,
so it is a vintage analogue approximation of pure white noise.
2 Pink Noise Out :
This is the Pink Noise Output and signal level is +/-5 Volts peak to peak. Pure pink noise is
white noise that has been ltered to reduce the volume of each increasing octave, which
compensates for the increase in the number of frequencies per octave. Each octave is
reduced by 3 decibels, resulting in a noise signature that has equal energy at every
octave. This pink noise is generated using the same discrete transistor circuitry as the
vintage Model D synthesiser and is an analogue approximation of pure pink noise.
3 Red Noise Out :
This is the Red Noise Output and signal level is +/-5 Volts peak to peak. Red (or Brownian)
noise is more heavily ltered than pink noise, at the rate of 6db/octave or more, so that it
has a much lower high frequency content. It is most commonly used as a random control
voltage rather than an audio signal.
4 Glide On/O :
This switch turns the Glide eect on/o. It is NOT a bypass switch, its function is the same
as turning the Glide Speed control fully counter clockwise.
5 Glide CV Input :
This is the Control Voltage (CV) Input to the Glide module. The acceptable input voltage
range is +/- 10 Volts. However only positive voltages (0 to +6 Volts) are processed,
negative voltages are ignored and voltages between +6V and +10v are limited to +6v.
The most common application would be to feed in a 1V/Oct signal from a Midi/CV
converter, however it’s use is not limited to this and the module can be used for many
dierent up/down slew eects.
