as per this answer here: https://answers.presonus.com/38058/increase-capacity-option-change-recording-quality-series?show=38089#a38089
the only option is to be able to adjust the quality of the recording so i can record on MP3 format etc. to save a lot space to the SD card, so not to be busy to swap sd cards & to have the extra pressure on a job to make sure card not going out of space.
Thanks
