Seems to me we need a thread that covers the original MixPre series and MixPre II series. The only other thread I see omits the MixPre10.
Anyway, SD released Firmware 7.17 today for the entire MixPre line. But yikes, it fixes "Rare, brief interruptions of audio in recorded files and USB outputs no longer occur." That sounds like a disaster, has that happened to anyone?
There is no mention that this firmware fixes my question about the Remix function when LR Mix is not recorded, and I haven't tested it. SD has not gotten back to me with any further comments.
