Advanced Edit Pattern Functions
Several advanced functions are available in the Edit Pattern and Step-Write Pattern modes that are not
shown on the control panel quick reference grid.
Ctrl + Alt Set Pattern Length: When you press and hold both the Ctrl and Alt buttons simultaneous-
ly, one of the eight Selector LEDs will be illuminated, indicating the current pattern length. To leave the
pattern length unchanged, release both buttons. To change the pattern length, hold down both the Ctrl
and Alt buttons button while pressing one of the eight Selector buttons.
For example, if you want to set the pattern length to 12 steps: First, make sure you are editing the
second half of the measure (the Alt LED should be illuminated). Then, press and hold both the Ctrl and
Alt buttons and press Selector button 12. Release all buttons, and the pattern length is now 12 steps.
Alt + Sel Various: Press and hold the Alt button, then press a Selector button to perform various
editing functions.

Scale: The scale function sets the number of steps per beat (quarter note). Four steps per beat is equiv-
alent to 16
th notes, and it is the typical setting for 4/4 time. Eight steps per beat is equivalent to 32 nd
notes, and it is great for fills. Three and six steps per beat is typically used for 3/4 time. The scale is
saved with the pattern.
Revert: The Revert function discards any changes you have made while editing a pattern. You can revert
just the current drum or the whole pattern. It reverts back to what it was before you entered the edit or
write mode.
Clear: The Clear function clears all steps for the current drum or the whole pattern.
Editing Built-in Patterns
All 64 patterns can be edited, however only the first 32 patterns (the first four banks) are saved when
you power off the LDB-1. Banks five through eight are built-in patterns and, even if they are edited, they
will be restored to their default when you power off the LDB-1.
