We have 2 series 3 32s mixers set up to run in paralle via 2 stages boxes. I want to take the SD recording from one mixer (that plays fine in sound check on its mixer) and use sound check on the 2nd mixer for training. I've recorded to SD on the 2nd mixer but it won't play back at all. The audio files are there as I downloaded them to Studio One and have played them on computer as single wave files.
The 1st mixer has no issue with recording or play back, so I know the card format and my operations are correct.
