During performance it can sometimes be useful to control the brightness of the LED's. Dazzling lights from your equipment on a dark stage for example don't always help to see what you are playing. The COBALT5S thankfully has a straightforward way of allowing you control the LED's to suit the environment you are performing in.
A quick way whilst performing can be to do this on the hardware.
Power on your COBALT5S, and turn the Page/Parameter dial until you reach Settings - UI & Controls.
Press the Page/Parameter dial so that the white line is below the lower text
Turn the Page/Parameter dial to the right until it shows LED Brightness.
You can then used the Preset/Edit dial to the right of the display to alter the number value and visually check the brightness of the LED's on the hardware that suits the environment you are performing in.
Launch the MODALapp, (v2.8.0 or above is required)
Power on your COBALT5S and click the Settings tab on the far right.
Use your mouse to click and hold the number value above the LED Brightness text. You can then use your mouse to raise or lower the number value and visually check the brightness of the LED's on the hardware that suits the environment you are performing in.
