I reported the unstoppable timecode running wild bug which effects the MixPre-6 to not respond to STOP button at all.
And got the highly ignorant copy paste reply from Sound Devices support regarding supported cards.
They did not even ask about the bug I reported.
Instead they made a comment
Looking up the cards you listed, it looks like two of them may be Micro SD cardsNone of the cards I listed was micro SD cards. They are full sized SDHC and SDXC cards from reputable manufacturers like Sandisk, Toshiba and Kingston.
I'm beginning to believe that Sound Devices support is drowned in tickets regarding cards so they revert to copy pasting in hope to close the ticket.
Thank you for contacting Sound Devices. You are correct that the only card that has been thoroughly tested for the MixPre Series is the SAM-32 SD card. However, as stated on our Approved Media page, “Many SD, SDHC, and SDXC cards from other reputable manufacturers, like Delkin or SanDisk, that meet or exceed class 10 speeds are acceptable.” (https://www.sounddevices.com/mixpre-series-approved-media-list/) Please use that to find SD cards that work for you.
Looking up the cards you listed, it looks like two of them may be Micro SD cards. If that is the case, it is not recommended to use Micro SD cards with the MixPre as they are highly likely to encounter errors.
Thanks,
