Hi everyone, I just did a live 8 track recording of my band with the zoom r24. Used an 8 gig sd card, 16bit, 44.1khz. While recording I frequently stopped and listened back to make sure I was getting a strong clean signal on all channels. No problems. Then I got home. I went to play back my tracks and there was no sound at all. I then took the sandisk out of the zoom and put it in my laptop. All the tracks were there, so obviously they were recorded. So what could be preventing me from hearing ANYTHING when I put this sd card in my R24? Already used it several times with no issues. Moved faders, made sure nothing weird was turned on, and when I imported the files into itunes everything was there, all eight tracks. So, what could be preventing the zoom from allowing me to do all the things I did just 2 hours ago? No led movement at all, all my markers were gone as well. Thanks in advance for any help with this.
