The Yamaha AN1x Synthesizer mailing list

My AN1x has ver 1.02 of the bios and it still makes popping noises when
cold. I spoke to a Technician from Yamaha Australia about this issue and
it seems to be a design fault. He mentioned that he had to re-route the
grounding from one of the boards internally . Newer versions have been 
modified and don't suffer from this problem. I find that this problem only 
occurs on cold days ,after a few minutes of warming up the popping noises 
disappear.
