I’ve noticed some bugs after an accidental electrical shutdown during a show and when i restart the gld 80, some parameters appears to be not at their previous values.
for example, sometimes when i change the equalization of some channel , i move the faders to make a curve on layer 1 , a different curve on the second layer ,i mute or demute some channels and I switch off the GLD . after restarting the device, these parameters doesn’t appears to be at the right value, the device didn’t kept on the last value modification.

Sometimes it’s OK sometimes not ; could you try to test if this problem appears on your GLD, try several times .
Thank
