Write Pattern Mode 

This is one of two modes in which you create and edit rhythm patterns.  In the Edit Pattern mode you 
select  a  drum  and  set  the  steps  on  which  that  drum  will  play.    In  the  Write  Pattern  mode,  you  go 
through each step sequentially, and select the drums that will play on that step. 

Selecting which pattern to write works the same as in Edit Pattern mode.  Please see the first four para-
graphs of that section. 

 Sel   Instruments:

  In  Write  Pattern  mode,  the  Selector  buttons  and  LEDs  represent  the  instruments.  

This is true whether or not the pattern is playing. 

 Run   Start / Stop:

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

selected  pattern  will  repeat  continuously.    The  Write  Pattern  mode  behaves  differently  depending  on 
whether the pattern is playing (Tap-Write) or the pattern is not playing (Step-Write).  You can press the 
Run button at any time to switch between the two behaviors. 

Tap-Write 

If the pattern is playing while you are in Write Pattern mode, this is referred to as Tap-Write mode.  Tap-
Write  mode  will  be  familiar  to  users  of  vintage  drum  machines.    In  tap  Tap-Write  mode,  the  pattern 
plays continuously.  If there are no instruments set on the currently playing step, then a metronome tick 
will be heard for that step.  Pressing a Selector button turns on the selected drum on the step that is 
currently playing.  You probably want to choose a slow tempo in Tap-Write mode.  

The

   Ctrl   

and

   Alt   

buttons have no effect in Tap-Write mode. 

Step-Write 

If the pattern is not playing while you are in Write Pattern mode, this is referred to as Step-Write mode.  
In Step-Write mode, you turn on or off the instruments for one step at a time.  The Selector LEDs indi-
cate which instruments are on for the current step.  Since the pattern is not running, you can take your 
time turning on or off the instruments. 

 Ctrl   Previous Step:

 While the Ctrl button is pressed, the Selector LEDs indicate the current step of the 

pattern which is being written.  Releasing the Ctrl button goes to the previous step. 

 Alt   Next Step:

  While  the  Alt  button  is  pressed,  the  Selector  LEDs  indicate  the  current  step  of  the 

pattern which is being written.  Releasing the Alt button advances to the next step.  

See  the  Advanced  Edit  Pattern  Functions  topic  in  the  Edit  Pattern  Mode  section  for  more  functions 
available in Step-Write mode.
