E The Store And Note Chase Buttons; F The Preview Button - Alesis D4 Reference Manual

After selecting the parameter to be edited, use the Data wheel to vary its value. Once
a Drum Set has been edited, a period appears in the display after the Drum Set
number. Example: This Drum Set has not been edited.
This Drum Set has been edited. Note the period.
The period reminds you that if the Data wheel is rotated and another set selected,
any changes made to the current Drum Set will be lost.

1.4E The Store and Note Chase buttons

The Store button saves edited Drum Sets by overwriting existing Drum Set data with
the contents of the edit buffer. Note Chase allows a MIDI note or acoustic trigger to
choose a particular note (and therefore its assigned drum sound) to be edited.

1.4F The Preview Button

You can tap the velocity-sensitive Preview button at any time to trigger the currently
selected sound.
