it would be very useful to save shows on the mixer as well…
why just on usb?
I’m sure the users of some of the other A&H systems (specifically the QU and SQ systems) ask this same question.
However I think it is pretty clear that it is not by mistake and it’s not likely to change.
how can you say that? not by mistake? it’s about improving… and it definitely makes sense load shows from the mixer and not just from usb… with other mixers is possible as well… so just a suggestion for the next update 
What I am trying to say is that this is a specific decision that has been made by A&H. You may not agree with the decision, but they obviously have their reasons for handling it this way.
If it was an oversite or a “mistake” that A&H wanted to correct, they would have done so on the newer systems like the CQ. The fact that they decided to handle show files in the same way as the QU & SQ systems tells me that it is not an oversight, but a conscious decision A&H has made.
