7.4.10 Editing Parameters not Accessible from the Front Panel
The front panel realtime update editing function can also be used to set the edit buffer value for
parameters that are normally inaccessible from the front panel. These parameters are:
Processor Offset (dec) Parameter name Reference
Dynamics Processor 0 Sidechain Filter Mode 0: Hipass Shelving
127: Lowpass
De-ess Processor: 22 Absolute Threshold See Attn100 Table
Expansion
Parameters
49 Expander Knee See Knee Table
Compression

55 Compressor Knee See Knee Table
AGC Parameters 56 Absolute Threshold See Attn100 Table
60 AGC Curve Knee See Knee Table

Modifying some of these parameters incorrectly can result in improperly operating modules, but
reloading the program will restore the original settings. To edit one of these parameters use the
realtime editing mode.
1. Cycle through the
MIDI switch until the display reads rEAL , then hold down the switch. The
display reads
bLC (Block).
2. Use the Wheel to select
SEt. Press the MIDI switch again. The display reads PAr .
3. Select the parameter to edit using the Wheel. (See Appendix C, “Realtime MIDI.”) The
OUTPUT HEADROOM display displays the 0-127 scaled level of the parameter. Press the
MIDI switch again. The display reads
oFt (Offset).
4. Use the Wheel to enter the desired value.
5. Press
LEAVE EDIT to exit the realtime editing mode.
6. When using the realtime modulation modes, the offset adjustment sets the new value
within a resolution of 2 steps.
Shortcut:
1. From any control level other than MIDI, press and hold the MIDI button to access the
realtime editor. The display shows
bLC (Block) when you are successful.
2. Use steps 2 through 6, above, to set the desired parameter.
