Plug   the   square   wave   output   of   the   “pulsing”   LFO   into   Duatt’s    IN A    and   connect    OUT B  
to   your   filter’s   frequency   CV   input.   Use   Channel A’s   attenuverter   to   set   the   amount   of  
pulse   you   want   to   hear.   Next,   plug   the   triangle   wave   output   of   the   “slow   sweeping”   LFO  
into   Duatt’s    IN B .   Since   nothing   is   plugged   into    OUT A ,    OUT B    contains   a   sum   of   Duatt’s  
A and B   channels.   Use   Channel   B’s   attenuverter   to   set   how   much   the   pulse   sweeps   up  
and   down   the   frequency   band.   You   now   have   two   different   CV   sources   controlling   one  
destination   by   varying   amounts.  

Audio   Mixing :   Audio   is   a   voltage   too.   So   you’re   probably   asking   yourself,   “Can   I   use  
Duatt   to   mix   a   couple   channels   of   audio   together?”   Yes,   you   can!  

Set   both   of   Duatt’s   polarity   switches   to    UNI    and   turn   both   its   knobs   fully  
counterclockwise .   Plug   the   output   of   one   oscillator   into    IN A ,   and   the   other   into    IN B .  
Connect    OUT   B    to   your   audio   amplifier,   and   leave    OUT A    un-connected.   Rotate  
Channel A’s   attenuator   clockwise   and   you’ll   hear   the   oscillator   connected   to    IN A .  
Increase   the   Channel B   attenuator   to   add    IN B    to   the   mix.  

Instant   Voltage   Doubling :   Channel A   has   a   dedicated   multiplier   switch,   which   doubles  
the   voltage   being   sent   to   its   input.   This   is   ideal   for   temporarily   pumping   up   a   CV’s   impact  
on   a   particular   parameter,   then   instantly   dropping   it   back   down   to   its   original   level.
