Live Sampling Buffre

After  some  experimentation  with  Buffre,  you  will  come  to  see  that  it  has  amazing 
creative properties for  sound manipulation and sound design, especially when you  start 
working with  loop segments  that  are  in  the range  of  1/128th  notes  to  1/1024th  notes.  
This is  the realm of  granular  synthesis where  looped audio takes on  a  new character.   
Experimenting with  these types of  tones often leads to new ideas,  and it is important to 
have  a  way  to  quickly capture  and  save  ideas.  Buffre’s  FX  sends  were  designed  to 
provide an  access point  for  resampling,  and  the example below  demonstrates  how to 
configure this setup and start building a palette of lo-fi bitcrush drum tones.

  

1. In   an   empty   song   session,   create   a   Dr.OctoREX   and   load   a   few   drum   loops.
2. From   the   Create    Menu   \    CreaJve   FX    submenu,   Select    “Buffre    Beat   Repeater”   to    add    the   

device   as   an   insert   effect   between   Dr.OctoREX   and   the   Mix   Channel.

3. Press   the   TAB   key   to   flip   to   the   rear   of   the   rack.
4. Locate   the   Sampling   Input   on   the   Audio   I/O   device,   and   disconnect   the   cables   coming   from   

Audio   Input   1/2   (default   seWngs).

5. Connect   Buffre   FX   Send   1   Outputs   to   the   Audio   I/O   Sampling   Inputs.   Then   hit   TAB   to   flip   back   

to   the   front   of   the   rack.

6. Create   a   ReDrum   Drum   Computer   and   from   the   contextual   menu,   Select   “Reset   Device”   to   

clear   all   preloaded   seWngs.

7. On   Drum   Channel   1,   set   drum   on   events   on   steps   1,   9,   and   15.
8.    Press   Play   on   the   Transport,   and   the   OctoREX   loops   should   begin   to   play.
9. Set   Buffre   to   Play   Mode   3   -­‐   Current,   Pitch   to   about   -­‐1100   cents,   and   set   the   Bitcrush   amount   

to   35%.      Then,   Enable   One-­‐Shot   mode   and   set   the   Manual   Trigger   Length   to   an   1/8th   Note.   

10.Press   the   Buffre   Manual   Trigger   buYon   to   audiJon   how   the   loop   sound   is   affected.      It   should   

sound   glitchy   and   lofi   like   an   old   console   video   game.      You   will   also   noJce   that   when   Buffre   is   

triggered,   a   signal   appears   at   the   Sampling   Input.

11.On   Redrum   Channel   1,   press   the   “Start   Sampling”   buYon   and   a   mini   recorder   window   will   

appear.

12.Press   the    Manual    Trigger    BuYon    on   Buffre   and    quickly    release   it.        On    the   Live    Sampling   

window,   press   the   stop   buYon.      Reason’s   sampler   automaJcally   adjusts   for   recorded   silence,   

so   the   new   glitchy   drum   tone   will   play   in   Jme   with   the   new   loop.

13.ConJnue   this   process   on   the   remaining   Redrum   Channels   with   different   Buffre   seWngs   like   

high   pitch   loops,   pendulum   loops   and   reverse   hits.

To    migrate    your    new    samples   and    drum    paYerns,    use   the   edit   menu    funcJons    to    copy    the   

enJre   Redrum   instrument   from   one   Reason      song   session   to   another.
