I assume that this is the section that you have read?
GeniusPro and Lightpalette Operators Guide
You can use the {BUMP}
softkey to bump the
current channel selection in the mode set by the [BUMP MODE] key and associated softkeys.
Press [BUMP MODE] to check the
current setting. The settings are displayed on the
console LCD.
Note: You can simulate the function of the [BUMP MODE] key on 300 Series consoles by pressing capital V on the external keyboard. The right three softkeys determine the operation of the
submaster bump buttons (refer to
Submaster section, Section 6). The left three softkeys determines what happens when you press the {BUMP}
softkey.
{FLASH} sets the {BUMP}
softkey so that the selected
intensity channels go to the
level set by the Flash Supermaster (refer to
Submaster section). If there is no Flash Supermaster, the bump
level is 100%.
{SOLO} sets the {BUMP}
softkey to turn off unselected
intensity channels without changing the levels of the selected channels. If previously set to {KEYS LATCH}, setting the bump mode to {SOLO} will automatically set the
submaster bump key mode to {KEYS ON}
{FLASH} + {SOLO} sets the {BUMP}
softkey so that the selected channels go to levels set by the Flash Supermaster and all other channels are set to off. If there is no Flash Supermaster, the bump
level is 100%.
Seems very similar to the
desk that I use, only the status is displayed via two
LED’s above the
button. Both off, One on, both on
etc.
