Miscellaneous
The Misc submenu, as the name suggests, contains master miscellaneous functions such as setting the LCD contrast, screen saver, and global preferences.
Contrast
This function changes the contrast of the front panel LCD so that it may be read easily from different angles. The contrast is adjustable from +7 to -8. Adjust the contrast for the most comfortable viewing.
v To Change the Contrast:
1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.
2.Press the Setup function key (F3). A second row of function keys appears.
3.Press the Misc function key (F3). The Miscellaneous menu appears.
4.Move the cursor to the Contrast field using the cursor buttons or by pressing the F1 function key.
5.Adjust the Contrast using the Data Entry Control, or INC/DEC buttons.
6.Press the Exit button twice to return to the Memory Statistics screen.
Wrap Field Selection
When wrap field selection is enabled, moving the cursor past the last selection in a window makes it automatically jump back up to the first selection. With wrap field selection Off, the cursor will NOT move past the last selection in a window. You have to use the up or left cursor button to go back.
v To Turn Wrap Field Selection On or Off:
1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.
2.Press the Setup function key (F3). A second row of function keys appears.
3.Press the Misc function key (F3). The Miscellaneous menu appears.
4.Move the cursor to Wrap Field Selection using the cursor buttons or by pressing the F2 key.

5.Turn Wrap Field Selection On or Off using the Data Entry Control or INC/DEC buttons.
6.Press the Exit button twice to return to the Memory Statistics screen.
Screen Saver
After a period of inactivity, the LCD backlight dims in order to prolong the life of the LCD. This parameter sets the period of time from 10 to 60 minutes (in increments of 10 minutes) before the screen dims, or “Never” so that the backlight always stays on. This option is not available on e64 or EIV units.
v To Turn the Screen Saver On or Off:
1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.
2.Press the Setup function key (F3). A second row of function keys appears.
3.Press the Misc function key (F3). The miscellaneous menu appears.
4.Move the cursor to Screen Saver using the cursor buttons.
5.Set the screen saver time using the Data Entry Control, or INC/DEC buttons.
6.Press the Exit button to return to Memory Statistics.
Disable Sound ROM
Sample memory is user-expandable up to 64 megabytes with standard SIMM modules (up to 128 MB if ROM access is disabled). To use more than 64 MB of Sample Memory with the Sound ROM upgrade installed, you must turn off the Sound ROM. This screen is only accessible if you have Sound ROM SIMMs installed.

Zero Crossing Threshold
Background
The term “zero crossing” refers to the point at which the positive slope of a waveform passes through zero. In many sample editing applications, such as splicing and looping, it is useful to locate zero crossings in order to make glitch-free joins and loops. On some signals, however, a simple zero crossing may not be effective because the signal contains excessive noise or low-level, high-frequency harmonics. In these cases, every few samples may cross through zero. By setting a zero crossing threshold, we can ignore lowlevel zero crossings and wait for the signal to reach a certain level before choosing the next zero-crossing. Zero crossing threshold sets a level that a signal must exceed before the next zero crossing with a positive slope is selected. The defined zero crossing threshold is used in the Auto-Truncate function or whenever you manually select a zero crossing using the cursor buttons.
The following diagram illustrates zero crossing in action. The small x marks the initial position.

To move forward through the sound to the next zero crossing, press the right cursor button, as shown in the previous diagram. EOS finds the first zero crossing on the positive slope after the signal has crossed the threshold.
To move backward through the sound to the next zero crossing, press the left cursor button. EOS finds the first zero crossing on the positive slope after the signal has crossed the designated threshold.

Undo/Redo Enable
O Although the Undo/Redo feature lets you backtrack only one step, you can repeat the Undo and Redo commands an unlimited number of times.
_ If you are using a removable media hard disk and do not have a fixed hard disk connected, it is recommended that you turn Undo/Redo OFF.
Use the Data Entry Control or INC/DEC buttons to select the zero crossing threshold. A setting of -96 dB will be the most sensitive; a setting of -30 dB will be the least sensitive. The selected zero crossing threshold is used in the auto-truncate function or whenever you manually select a zero crossing using the left/right cursor buttons. If auto truncate does not seem to be working well, try adjusting the zero crossing threshold.
v To Set the Zero-Crossing Threshold:
1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.
2.Press the Setup function key (F3). A second row of function keys appears.
3.Press the Misc function key (F3). The Miscellaneous menu appears.
4.Move the cursor to Zero-X Threshold using the cursor buttons or by pressing the F5 function key.
5.Set the desired zero-crossing threshold using the Data Entry Control, or INC/DEC buttons.
6.Press the Exit button twice to return to the Memory Statistics screen.
Undo/Redo Enable
During many Sample Editing operations, the sample being processed is backed-up automatically and stored on the system drive. If you do not like the results of the processing, with Undo enabled you can call up the Undo function and restore the original sample from the system drive. (Ah, if only life itself were so simple.) Best of all, the processed sample is backed-up also. Therefore, if you decide you liked the processed version better after all, you can actually undo the Undo (Redo).
If you are running low on disk drive space, the display will inform you if there is not enough memory to back up a sample onto the system drive. You then have two choices: either free up some additional memory by erasing banks on the system drive, or disable the Undo/Redo using this function.
v To Enable and Disable Undo/Redo:
1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.
2.Press the Setup function key (F3). A second row of function keys appears.
3.Press the Misc function key (F3). The Miscellaneous menu appears.
4.Move the cursor to Undo/Redo Enable using the cursor buttons or the F6 function key.
5.Enable or disable Undo/Redo using the Data Entry Control, or INC/ DEC buttons.
6.Press the Exit button twice to return to the Memory Statistics screen.
