External Input
The Mixer section has an external audio input. You can connect another audio source here - for
example, the output from another synth module - and use Circuit Mono Station’s envelope, filter
and mod sections to treat it. You can even connect the output of Circuit Mono Station to itself:
this “recursive” connection can produce some extreme and startling effects!
The external input is a standard ¼” jack socket
2
on the rear panel.
The
Audio In
control adjusts the level of the external input in the mix. You can also adjust the
gain (or sensitivity) of the input stage by holding down
Shift
15
and adjusting the same control:
this will allow Circuit Mono Station to accept a wide range of signal levels. Note that although all
the Mixer level controls are automated (see “” on page 57), the shifted Gain function of Audio
In is not automated.
You can use the External Input to configure Circuit Mono Station as a filter/
distortion effects unit. Program an Osc 1 Pattern with a single note on Step 1
which sounds for the whole bar (16 Pattern steps) – this will keep the
envelope open. Turn all Oscillator level controls down in the mixer. The signal applied at
the External Input can now be treated by the Filter and Distortion sections.

The sum created in the mixer from the various signal sources is fed to the Filter Section. Circuit
Mono Station’s filter section is both simple and traditional, and can be configured with only a
small number of single-function controls.
By default, the Filter Section affects all the signals fed to the Mixer Section. An unusual feature
in Circuit Mono Station is that you can choose not to apply the filter to Oscillator 2 and/or the
Noise signal with the
Bypass
button
35
. Successive presses of Bypass switch the filter out of
circuit for the Noise source, Oscillator 2’s waveform, or both of these, in turn. The sources being
bypassed are indicated by the two LEDs above the button. A further press cancels the bypass
function and returns the filter to affecting all sources.
