What is the maximum current draw from USB for the Logic Pro 16 ? That is, with the maximum sample rate, all channels operating, etc. In other words, worse case. An exact number is not needed. Is it less than 500mA ?

@gahelton1 Logic Pro 16 will sit at around 500mA consumption during a capture with all analog channels enabled. I expect worst case with all digital channels enabled would be slightly higher than this (say ~600 mA max as a rough estimate).
