I really wish Presonus could change to writing a single multitrack file like the M/B company. Single file stream would even make the board not nearly as picky about even officially supported SDHC cards. Make a split tool for the single 32-34 track file on your computer.

Surely there's enough DSP to handle changing to a single multi-track file stream.

stingray1122 wroteThe maximum size SD Card supported is 32 GB. At 48kHz this will yield roughly 1 1/2 hours of recording for 32 channels.

So I bought All suggested sd cards , did overwrite and speed test never is complete , I also did factory reset as some said this fixed bug , still speed test incomplete. It shows sd card is placed in with name and speed but never accomplishes speed test. Can you help please , TY
