GENERAL EDITING PROCEDURE
The TG500 makes editing easy by providing a consistent, logical control interface
via which parameters can be located and edited. Once you've learned the general
procedure, you can locate and edit any of the TG500's many parameters quickly and
easily.
Edit Mode Access
The TG500 voice, performance, and multi edit modes are are accessed by
first selecting the corresponding play mode via the [PLAY MODE] key, and
then pressing the [EDIT/COMPARE] key. This takes you to the top level of the
edit mode function "tree."
The only exception is the "Wave Edit" mode which is accessed by pressing
the [EDIT/COMPARE] key from the Utility mode "5:Wave" screen (page 237).
