Play Patterns Mode 

There are 64 patterns organized into eight banks of eight patterns each.   

 Sel 

  

Patterns:

 Pressing one of the eight Selector buttons selects the pattern to play within the current 

pattern  bank.    The  LED  corresponding  to  the  currently  playing  pattern  is  illuminated.    If  a  pattern  is 
playing  when  a  different  pattern  is  selected,  the  new  pattern  will  not  start  playing  until  the  current 
pattern finishes.  The LED corresponding to the new pattern will blink letting you know that it will play 
next. 

 Run   Start / Stop:

  The  run  button  starts  or  stops  playing  the  selected  pattern.    While  running,  the 

selected pattern will repeat continuously.  A pattern can be selected while not running and that pattern 
will play when the Run button is pressed. 

 Ctrl   Select Pattern Bank:

 When you press and hold the Ctrl button, one of the eight Selector LEDs will 

be illuminated, indicating the current pattern bank.  To leave the pattern bank unchanged, release the 
Ctrl  button.    To  change  the  pattern  bank,  hold  down  the  Ctrl  button  while  pressing  one  of  the  eight 
Selector buttons. 

 Alt   Patterns / Drums:

  Pressing  the  Alt  button  toggles  between  Patterns  and  Drums  behaviors.   

Pat-

terns

 behavior is as described above.   

Drums

 behavior allows you to play individual drums over top of a currently running pattern by pressing 

the Selector buttons.  The Alt LED will be illuminated when the Drums behavior is selected. 

Chaining Patterns 

Chaining  refers  to playing a repeating sequence of patterns.  To chain patterns, hold down a  Selector 
button to select the first pattern.  While still holding down the first button, press one or more additional 
buttons.   

The selected chain of patterns will begin playing when you release all of the buttons and after the cur-
rently playing pattern is complete.  If there is no pattern running, the chain will begin when you press 
the Run button. 

For example, press and hold Selector button 1.  While still holding down Selector button 1, press Selec-
tor button 2, then press  Selector button 3.  When you release  all of the  buttons, the  LDB-1 will begin 
playing pattern 1.  When pattern 1 is complete, it will play pattern 2, then pattern 3.  Then it will repeat, 
starting back at pattern 1. 

You  do  not  have  to  hold  all  of  the  Selector  buttons  simultaneously.    As  long  as  one  Selector  button 
remains pressed, you are creating a chain.   

The chained patterns do not have to be contiguous.  For example, you could chain patterns 1, 3 and 5. 

The chained patterns do not  have to be  sequential.  For example, you could chain patterns 1, then 5, 
then 3.  The chain runs in the order that you press the buttons. 

You can chain up to eight patterns within a single pattern bank. 

The Drums behavior works with chained patterns as well.  After selecting a chain, press the Alt button.  
The chain will continue to play and you will be able to play individual drums over top of the currently 
running chain of patterns.
