I've experienced similar problems with the Synthrotek Deluxe Power. The influx capacitance of the WMD dual VCA by itself is too much for the power supply to handle. It won't run properly with that module plugged in by itself. I also have intermitten issues with the Deluxe Power behaving as if I'm drawing too much power, but I've checked the voltage and I'm way under capacity. The USB power slot shorts out the system, not matter how small the power draw. Customer service hasn't been much help either.
