In   the   following   picture   you   can   see   the   floorplan   of   the   synthesizer.   The   sound   'flows'   from   left   to   

right,    following    the    classic    subtractive    synthesis    chain    (that    in    this    case    is    just    a    'topologic'   

reminder,   being   a   full   modular   synthesizer   without   normalled   paths).   From   the   oscillator   to   the   

filter,   to   the   vca   and   finally   to   the   headphone/line   out,   the   path   is   clearly   visible   on   the   overlay:   

   

   

fig.2   NS1nanosynth   floorplan   

   

The   NS1nanosynth   is   divided   in   three   main   areas:   the   Arduino/DAC/digipot   headers   (on   the   LEFT),   

the   main   Modular   synth   area   (including   the   ribbon   controller)   in   the   MIDDLE   and   the   Digital   and   

Sensor   headers   on   the   RIGHT.   

Regarding   the   middle   section   take   a   moment   to   learn   the   logic   of   the   module's   connections.   It's   

quite   simple   to   understand   that   the   lower   row   of   headers   is   linked   to   the   main   modules   (the   ones   

with    potentiometers,    such    as    VCO,    ADSR,    VCF,    etc...)    and    the    upper    one,    with    the    notable   

expception   of   the   LFOs   output   (SQU   and   TRI,   for   both   LFOs)   are   the   utility   modules   that   does   not   

have   direct   manual   control.   

This   manual   will   describe   in   detail   all   the   aforementioned   modules,   the   basic   sketch   loaded   on   the   

Arduino   Leonardo   and   its   functions   and   finally   a   series   of   patches   and   techniques   to   obtain   the   

maximum   from   this   small   but   powerful   machine!!!!   

   

   

Functional   Description:   

A   quick   word   on   the   philosophy   of   this   machine.   The   NS1nanosynth   has   been   developed   with   a   

few   important   things   in   mind:   

 

0-­‐a   good   sounding   synth   

 

1-­‐completeness   

 

2-­‐affordability   

 

3-­‐portability
