[[File:er-301-hard-buttons.png|thumb|300px|The ER-301 has 6 hard buttons whose basic functions are the same regardless of the UI context.]]
[[File:er-301-fine-coarse-button.png|middle]]Toggle knob sensitivity between fine and coarse settings.
<br clear=all>[[File:er-301-cancel-button.png|middle]]Used to abort an action. In general, it is the opposite of the ENTER button. <br clear=all>[[File:er-301-home-button.png|left]]The HOME button reverts encoder focus to the "beginning" or "top" of the construct that is currently focused. For example, if you are focused inside a unit then pressing the HOME button will shift the focus to the unit's header area. If you press HOME again, then the focus shifts to the chain's header area, and so on. Holding SHIFT while pressing the HOME button will zero out a focused parameter. <br clear=all>[[File:er-301-enter-button.png|left]]The ENTER button confirms a selection or operation. This is not to be confused with focusing an item which is always done via the soft buttons. For example, choosing a sample to load in the file browser or, during unit renaming, committing text that you just typed as the new name of a unit. <br clear=all>[[File:er-301-up-button.png|left]]Whenever you have focused an item (for manipulation) or dived into a new area (such as a modulation chain of a unit) you can return to the previous focus by pressing this UP button. It is very much like the BACK button a modern web browser. <br clear=all>[[File:er-301-shift-button.png|middle]]The SHIFT button is used to access alternate functions that some buttons have. These will be noted as they come up in the documentation.
