Position Actions

Three  buttons  comprise  the  playback 
action  controls:  Reset,  Backwards 
Quarter  and  Advance  Quarter  Buttons.  
Pressing one of  these buttons shifts  the 
looping  segment.    If  the  loop  engine  is 
not  engaged by a  trigger,  these buttons 
have no effect. 

Backwards Quarter

Pressing the Backwards Quarter Button shifts the playback loop segment backwards by 
a  quarter  note.    You  can  continue  to  shift  the  playback  segment  until  you  reach  the 
beginning of the audio stored in  memory.   When  you shift the segment backwards, the 
display will  scroll  to  update the  loop  section.    When  a  loop is  triggered,  the  segment 
starts at the zero position, and you will not be able to shift backwards.

Advance Quarter

Pressing  the Advance  Quarter  button  shifts  the  playback  loop segment  forward  by a 
quarter  note.   You  can  press the Advance Quarter  button  several times until you  reach 
the  end  of  the  audio  stored  in  memory,  and  the  waveform  segments  will  shift  to 
correspond to the section of audio being looped.

Reset

Pressing the Reset button  immediately  forces the loop  to restart at the beginning of the 
loop cycle.  

Loop On Disabled

As  previously described,  when  the  Loop On  button  is  disabled,  audio  stops  playback 
when  the loop  reaches the end of  the cycle.   If  a  loop  is held in  memory,  pressing the 
Reset  button  will  restart  the  loop for  another  cycle.    When  Buffre  is  in  Current  Play 
Mode mode with Loop  On Disabled, the device acts as a sampler  which then allows you 
to play the sample by pressing the Reset Button or triggering Reset with a Gate Trigger. 

Position Gate Inputs

These controls can also be triggered by  Gate signals connected to the input sockets on 
the back panel of Buffre.
