(EN) Controls
(1) FADER 1 – this fader has two
functions: in free-running mode
it sets the frequency for LFO 1;
otherwise it acts as a master
fader for the other three faders to
reference.
(2) FADER 2 – in free-running mode
this acts as frequency control for
LFO 2; otherwise it acts as an offset
against the master for LFO 2.
(3) FADER 3 – as fader 2 but for LFO 3.
(4) FADER 4 – as fader 2 but for LFO 4.
(5) FREE LED – when this LED
is lit the FOUR LFO is in
free-running mode.
(6) MODE – use this switch to
select the action for sockets 16.
In RESET mode a gate applied
to the socket(s) will cause the
waveform(s) of the LFO(s) to reset;
in SYNC mode the LFO(s) will sync
to a clock sent to the socket(s).
(7) TOGGLE – use this button to
switch between:
• Free-running, where the four
LFOs work independently.
• Quad, where LFOs 2 – 4 are
slaved to LFO 1 but are 90°,
180°and 270° out of phase
Quick Start Guide
respectively. Faders 2-4 and
sockets 10-12 control the
amplitude of LFOs 2-4.
• Phase, where faders 2-4 set
the phase of LFOs 2-4 against
LFO 1. Sockets 10-12 allow
further control of shift from
external CVs.
• Divide, where faders 2-4 set
divisions of LFO 1's frequency
for LFOs 2-4. Sockets 10-12
allow further CV control.
(8) ASSIGN – sets the waveform that
will be output from sockets 18.
Choose between sawtooth, ramp,
triangle and trapezoid. This is a
global setting which will affect all
four LFOs.
(9) FREQ – use this socket to control
the frequency of LFO 1 from an
external CV source, in the range
-5 V to +5 V.
(10) (11), (12) – FRQ/PH/DIV – use these
sockets to allow external CV control
of LFOs 2-4 according to whichever
mode the FOUR LFO is in. range in
all modes is -5 V to +5 V.
(13) QUAD LED – this LED is lit when
the FOUR LFO is in Quad mode.
(14) PHASE LED – this LED is lit when
the FOUR LFO is in Phase mode.
