Manual   Controls:   ATTEN1   and   ATTEN2.   Input   

Output:    There    two    inputs    and    two    outputs   

for    each    attenuator.    Tech    Specs:    consider   

that,    with    regard    to    impedances,    the   

attenuator   

is   

passive   

and   

parallel   

configuration   of   input   and   output   signals   (i.e.   

more   than   one   signal   at   the   input)   will   modify   

the    relative    impedances    as    well.    This    is    not   

dangerous    at    all    but    can    lead    to    different   

results   than   the   one   you   imagined!   

   

 

CVGEN   (CONTROLLERS):

   CV   generators:   

There    are    two    active    CV    generators    on    the    NS1nanosynth.    Those    voltage    sources,   

controlled    by    their    relevant    knobs    (CTRL1    and    CTRL2)    simply    generates    at    the    output    a   

voltage   from   0   to   5V.   It   could   be   used   for   any   purpose   including   connected   to   the   Arduino   

analog   pins   to   dial   parameters   and   configurations   into   an   alternative   firmware.   

Manual    Controls:    the    two    knobs    CTRL1    and   

CTRL2.    Input/Output:    The    module    have    two   

outputs    C1    and    C2.    Tech    Specs:    The   

CVGEN/CONTROLLERS    module    has    buffered   

outputs.   This   means   that   you   can   hook   up   the   

output    C1    to    different    inputs    (using    a    mult)   

without    degradating    its    qualitites.    General   

concept:    a    buffered    output    will    not    suffer   

from    a    wide    range    of    input    impedances    adn   

could   also   drive   small   loads   like   LEDs,   headphones   etc...   

   

 

RIBBON   CONTROLLER

:   

One    of    the    most    immediate    and    intriguing    features    of    the    NS1nanosynth    is    its    Ribbon   

Controller,    a    100mm    resistive    linear    potentiometer    that,    through    a    specialized    circuitry   

becomes    a    fun    to    use    playing    interface.    The    patch    section    of    the    Ribbon    Controller    (top   

right,   near   the   robot!)   generates   a   couple   of   identical   GATE   signals   when   you   press   on   the   

ribbon   and   presents   two   different   CV   outputs   (that   shares   the   range,   from   0   to   5V   going   

from    left    to    right    on    the    ribbon).    The    first    one,    CV,    is    the    exact    information    about    your   

finger's   position   on   the   ribbon,   including   the   return-­‐to-­‐zero   when   you   lift   your   finger.   The   

HLD   is   holding   the   voltage   with   an   internal   S&H   to   allow   you   to   use   release   times   on   the   

ADSR   (for   example)   and   other   techniques.   

Manual    Controls:    the    Ribbon!    There    is    also    an   

LED    that    lights    up    when    a    GATE    is    detected   

(finger    down).    Input/Output:    GATE,    goes    high   

when   the   finger   is   on   the   ribbon.   CV   outputs   0   

to    5V    (from    left    to    right),    HLD    outputs    0    to    5V   

even    when    the    finger    is    lifted    from    the    ribbon.
