4 CV knobs (upper row)
You use the CV knobs 4 (upper row) to set the
voltage output for each step in the upper analog CV
row. The control voltage set for each step is output at
the upper Pre Out § socket.
The range of voltage output can be controlled with
the range switch 6. Three very accurate voltage ran-
ges are provided (see below) so that the upper analog
CV row is ideally suited for precise VCO pitch control.
5 CV knobs (lower row)
You use the CV knobs 5 (lower row) to set the voltage
output for each step in the lower analog CV row. The
control voltage set for each step is output at the lower
Pre Out § socket.
You use the Scale control 7 to adjust the range of
the voltages controlled by the CV knobs.

If for any step you patch in an external CV /
audio input (socket $), the corresponding-
knob in the lower row doesn't put out its own
voltage.
Instead, it acts as an attenuator for the
external CV / audio signal, before sending it
to the lower Pre Out output §.

6 Range
The position of the Range switch (a three-way toggle
switch) 6 selects the precise voltage control range,
within which the upper row of CV knobs 4 will operate.
There are three ranges to choose from:
• up :
• centre : 2 V
• down : 4 V
The maximum voltage is obtained by turning the knobs
fully clockwise.
7 Scale
Control 7 sets the range of control voltages, within
which the lower row of CV knobs 5 will operate. If an
external CV / audio signal is patched into any of the
sockets $, the scale control affects the amount of
attenuation the CV knob will produce on that voltage.
8 Glide
The internal slew limiter's rate is set with control 8.
If for the current step in a sequence (e.g. step three)
the slew limiter is switched in (by a "low" control
signal at the Glide Ctrl. § socket), the control voltage
sent to output Post Out § doesn't jump instantly from
the voltage at the previous step (in this example, step
two). Instead, it glides gradually to the new voltage, at
