LFOs Overview

The SWN features six LFOs, one for each channel. Each LFO has an output jack which can be patched to CV
jacks on the SWN or other modules. The speed, waveshape, amplitude, and phase of each LFO can be controlled
individually. Typically, the LFOs are constantly running, but there are two modes where they behave like
envelopes by firing only when a note is triggered (Note Mode and Keyboard Mode).
Using the LFO->VCA button, the LFOs can be internally routed to the channel VCAs to modulate the volume of
each channel. Using the !
trigger.
The LFOs are all synced to a common clock called the base tempo. A global clock divider/multiplier divides or
multiplies the base tempo to produce the global tempo. Each LFO also has a clock divider/multiplier that takes the
global tempo and produces the LFO's tempo. The base clock tempo is 2Hz by default. Patching a clock into the
Ext Clock jack will sync the base clock to the external clock.

LFO Speed

The global clock divider/multiplier is controlled by turning the LFO Speed knob without holding
down any Channel Buttons. Each LFO's clock divider/multiplier is controlled by holding down one
or more Channel Buttons while turning the LFO Speed knob.
Turning LFO Speed steps through integer dividers and multipliers of the base or global clock. The
sequence of integers is as follows:
÷64 ÷48 ÷32 ÷24 ÷16 ÷8 ÷7 ÷6 ÷5 ÷4 ÷3 ÷2 = x2 x3 x4 x5 x6 x7 x8 x12 x16 x24 x32
The sequence is infinite in both directions: when slowing the tempo down past ÷64 the tempo
divides by a factor of eight more than the previous factor (÷72, ÷80, ÷88, etc..). When speeding the
tempo up past x32 the tempo multiplies by a factor of two more than the previous factor (x34, x36,
x38, etc...) Holding down Fine while turning LFO Speed adjusts by non-integer amounts.

LFO CV jack

The LFO CV jack is an input jack which controls the global LFO tempo. Inputting CV in the range of
0V to +5V will increase the global clock's tempo by offsetting what's been set by the knob.
