Configuring  an  EQ  in  Logic  Pro  X  “Hi!  I  am  Eduardo  Motta  from  Antigua,  Guatemala,  a  small  country  in  Central  

America.  I´m  an  electrical  engineer  and  studying  music  production  has  always  been  my  passion.  This  lesson  is  for  week  5  of  Introduction  To  Music  Production  at  

Coursera.org.  I  will  be  teaching  how  to  configure  an  EQ  channel  to  function  like  a  largo  format  mixing  EQ  section  in  Logic  Pro  X”  

As   we   learned   this   week   EQ   is   one   of   the   most   important   elements   in   music  production.  In  the  following  assignment  I  will  demonstrate  the  configuring  of  an  EQ  plugin  to  function  like  a  large  format  mixing  console  EQ  section  in  Logic  Pro  X.  I  will  work  with  the  settings  shown  in  the  material.    

   

High  pass  filter,  75hz  18dB/OCT      High  shelving  filter        Mid-­‐High  Band  pass  filter    

     

 Low-­‐Mid  Band  pass  filter      

   Low  shelving  filter      

Those  are  the  basic  elements  we  will  show  in  the  Channel  EQ  that  comes  with  Logic  Pro  X.  Which  is  the  following:    

   In  the  upper  left  corner  we  see  a  on  button,  that  will  be  useful  to  bypass  the  EQ  and  see  the  result.  Next  to  it  you  can  see  a  window  that  will  give  a  variety  of  options.  In  this  window  is  where  we  can  find  a  variety  of  pre  sets  for  the  EQ  channel,  included  your  own.  Here  you  can  save  as,   if   you  want   to  use   it   later;  but  you  also  have   the  option   of   Save   As   Default   which   will   allow   you   to   make   the   basic   analog   mixer  parameters  you  default  as  we  learned  in  class.  This   is  how  to  save  the  setting  as  a  preset  in  Logic  Pro  X.    

 

High  pass  filter    As  we  can   see  here,   this   is   a  high  pass   filter  with  more  options  than  the  one  we  find  in  a  mixing   console.   The   curve   in   the   upper   left  corner   is   the   activation   element,   if   its   red   it  means   that   is   activated   and   the   high   pass  filter  is  on.  Down  we  have  first  the  frequency  at   which   we   want   the   filter   to   star  functioning,  then  we  have  how  many  dB  will  be   attenuated  with   each   octave,   this   can   be  see   graphically   with   the   two   parallels   bars  that  surround  the  location  point.    And  the  last  element  will   give   us   the   vertical   position   of  the  point.      

   

   

Low  shelving  filter          The  high  shelving  filter  will  be  the  following  element   from   left   to   right,   this   element   in  Logic  Pro  X  will  usually  be  in  yellow,  helping  differentiate  between  the  two.  As   in   the  past  filter  the  definition  box  bellow  will  determine  for   starters   the   frequency   at   which   it   will  start   working,   then   the   amount   of   dB   you’d  like   to   reduce   or   augment,   and   the   ratio   at  which  the  filter  starts  working.                

         

Band  pass  filter  (1,2,3  and  4)          The   band  pass   filter   in   logic  works  with  the   same   three   parameters   as   the  shelving   filter   did.   The   first   one   is   the  frequency  at  which  it  will  star  to  filter  the  sound,   then   comes   the   attenuation   or  augmentation   and   in   the   en   the   ratio   at  which   the   filter  will   affect   the   frequency  spectrum.   At   the   difference   with   an  analog  mixer  that  might  just  have  two  of  these,   in   Logic   Pro   X  we  have   4   that  we  can  move  as  we  desire.                

 

High  shelving  filter    Our   high   shelving   filter   is   of   great  importance  to  be  able  to  give  presence  of  focus   to   certain   element;   it   works   with  the  same  parameters  as  the  low  shelving  filter.   After   this   one   we   can   use   a   Low  pass  filter  to  reduce  hiss  or  some  kind  of  unwanted  noise.                        

   

Final  EQ    

     

EQ  controls    During  this  assignment  we  have  been  using  our  EQ  with  the  graphics  display,  it  can  also  be  displayed  with  controls,  giving  us  more  specific  options  for  each  filter,  and  more  options  for  the  channel  EQ  in  general.  We  can  find  it  in  the  View  menu  in  the  upper  right  corner.      

       

                       

 “Thank  you  for  reviewing  my  homework  for  this  week.  I  hope  its  useful  for  anyone  interested  in  using  Logic  Pro  X.  The  channel  EQ  in  Logic  is  great  and  easy  to  use,  but  its  important  to  understand  how  it  works  and  the  different  options  you  might  be  

able  to  use.”
