You   can   also   implement   button   driven   'rolls'   on   the   melodic   lines   et...   With   the   optional   

involvement   of   the   Arduino   platform   this   could   lead   to   complex   sequencing   like   euclidean   

rhythms    and    rhythmic    arpeggiators...    The    NS1nanosynth    includes    two    NOT    gates   

(inverters),   one   AND,   one   OR   and   one   NAND   port,   each   of   those   freely   connectable.   

Manual    Controls:    NONE.    Input/Output:    inputs    and   

outputs    to    the    various    logic    gates    are    indicated    by   

entering    and    exiting    arrows    on    the    connector    pins.   

Tech    Specs:    Buffered    CMOS    integrated    circuits    are   

used   on   this   part   of   the   circuit.   Please   have   a   look   at   

the   datasheets   of   this   family   to   learn   more.   

   

   

 

CKDIV

   (clock   divider):   

The   clock   divider   section   of   the   NS1nanosynth   comprises   a   standard   cmos   ic   that   divides   

the   frequency   of   the   incoming   digital   signal   from   /2   up   to   /64.   The   RES   (reset   input)   allows   

to   restart   the   internal   counter.   This   block   could   be   used   to   generate   sub-­‐oscillations   from   a   

VCO,   output   triggers   that   will   be   likely   processed   with   logic   gates   etc...   

Manual   Controls:   NONE.      

Input/Output:   as   described   above.      

Tech   Specs:   NONE.   

   

   

   

 

CVDIV

   (voltage   divider):   

The   NS1nanosynth   have   two   variable   passive   attenuators.   To   put   in   place   another   one   of   

those   really   useful   modules   we   implemented   a   fixed   voltage   divider   (attenuator)   that   will   

allow   the   user   to   obtain   a   fixed   attenuation   of   2/3   1/2   and   1/3   of   the   orginal   signal.   As   the   

voltage   divider   is   made   with   resistors,   the   consideration   on   impedance   will   apply.   Again,   

this   will   not   disrupt   you   synth   but   it   may   held   different   results   from   what   you   expect.   

Manual   Controls:   NONE.      

Input/Output:    There    is    one    CV    or    AUDIO    input   

marked   with   an   ingoing   arrow   and   three   outputs   

at   the   various   attenuation   'taps'.      

Tech    Specs:    this    module    is    actually    a    resistor   

network   and   you   can   basically   use   concurrently   all   

the   outputs!
