SD CARD INFORMATION
SD or SDHC cards can be used in myMix for multi-track recording and play back as well as firmware updates. There are many cards available on the market, but not all work with myMix and not all achieve the same quality result.
COMPATIBILITY
In order to work with myMix SDHC cards need to be compliant with the SDA 2.0 specification. From firmware version 1.41 on, myMix will check SD cards for SRC entries. If these are not available, myMix will create an error message. The biggest card size supported in myMixfor recording is 32GB. For firmware updates SD cards should be 16GB or less.
SD cards differ in performance such as reading and writing speed and quality of data (data errors in bad sectors). Especially recording onto a SD card is challenging. myMix can record up to 16 mono or 8 stereo tracks plus the stereo mix. As 24-bit / 48kHz time-stamped wav-files this represents a 1,15MB data flow per second, per channel, so nearly 21 MB/sec. There are software tools available to check the actual performance of an SD card, such as h2testware.

*the myMix operation system supports a max. file size of 2GB, that means a individual recording session can last 2h and 4 min.
** our experienced is based on the use of several cards from each make and type, however, SD cards are made in bulks and the actual performance can vary.
