I am able to turn all LEDs on using the Brain V2 configurator, but when I try to turn LEDs on individually, those connected to column 1-4 work, but those connected to columns 5 and above don't respond.
I also try turning on all LEDs using the configurator utility that sends all CCs sequentially and the utility that sends all Notes sequentially (I send CCs with value 127 and Notes with Velocity 127), but those "serviced" by Column 5 and above don't respond.
Can anyone shed light on this?
Thanks,
Gabriel
