MIDI Quantize Combinator

The Thor  Polysonic  Synthesizer Step  sequencer  can quantize events that trigger  Buffre 
or  other  processes  in  Reason.    When  the  Reason  transport  is  running,  Thor’s  Step 
Sequencer  will only engage at a  time division set by  the sync  rate value.   For  example, 
if sync  rate is set  to 1/1,  the sequencer  will  start  at the beginning of  the next measure 
after  the  “Run” button  is enabled; or  if  sync  rate is set  to 1/4,  the sequence begins,  in 
time with  the transport,  at  the beginning of  the next  quarter  note beat.     The following 
example demonstrates how to configure Buffre to work with a Thor Quantizer patch.

1. Start   with   an   empty   Reason   song   session,   and   create   a   Dr.OctoREX   Loop   player.
2. On   the   DrOctoREX,   click   on   the   patch   browser   and   load   the   following   patch:   Reason   Factory   

Sound   Bank   /   Dr   Octo   Rex   Patches   /   Drums   /   Electronic   Drums   /   -­‐Bomb   Squad   (BSQ)   /   

Bomb   

Squad   |   Beats   110-­‐121   bpm   -­‐1.drex

3. Click   on   the   Dr.OctoRex    Device    to   set    the    focus    (click   on   a    non    control   area   like   the   rack   

screws   or   the   Jtle   graphics).

4. Create   a   Buffre   Beat   Repeater.       Buffre   should   be   inserted   between   the   Dr.OctoREX   outputs   

and   the   mix   channel   device   inputs.

5. Right   Click    on   Buffre,   and   on   the   contextual   menu,   select   the   item   “Combine.”       Buffre   will   

now   be   nested   inside   a   combinator   sub-­‐rack.

6. Inside    the    Combinator    sub-­‐rack,    create    a    Thor    Polysonic    Synthesizer.        Only    the    step   

sequencer   is   used,   so   it’s   unnecessary   to   route   audio   connecJons.      

7. Click   on    the   Thor’s   “Show    Programmer”   buYon,   and   then    reset   the   patch:        Right    Click   on   

Thor   and   select,   “Reset   Device”.

8. On   the   Thor   ModulaJon   Bus   RouJng   SecJon,   set   Mod   1   Source   to       MIDI   Key-­‐Gate;   Mod   1   

Amount   to   100;   and   Mod   1   DesJnaJon   to   Step   Sequencer-­‐Trig.

9. Set   Mod   2   Source   to   MIDI   Key-­‐Note;   Mod   2   Amount   to   100;   and   Mod   2   DesJnaJon   to   Step   

Sequencer-­‐Transpose.

10.   On   the   Thor   Step   Sequencer,   Set   Run   Mode   to   “Repeat”;   set   the   Rate   to   1/4;   and   set   Steps   

to   1.      

11.   Next,   set   the   EDIT   knob   to   “Gate   Len.”   and   adjust   the   step   1   knob   unJl   the   value   indicates   

100%.

12.   Hit   the   TAB   Key   to   view   the   rear   of   the   rack.
13.   Connect   the   Thor   Step   Sequencer   Note   CV   output   to   the   Buffre   CV(Loop   DuraJon)   socket;   

and   connect   the   Thor   Step   Sequencer   Gate   /    Velocity    CV   output   to   the   Buffre   Gate(Trigger   

Loop)   CV   input.

14.   Hit   the   TAB   Key   to   return   to   the   front   of   the   rack,   and   set   Buffre   Mode   to   3:   Current   Mode.
15.   On   the   Sequencer   Track   List,   Click   on   the   “Combinator   1”   track   to   select   it.
16.   Press   Play   on   the   Sequencer   Transport,   and   start   playing   notes   in   the   range   of   D1   to   F3   to   

trigger   the   beat   repeater.
