Make sure the snare levels are set high enough in the 2Box mix page, and make sure the snare sound is set high enough. You can also try increasing the gain a little. Do this before editing the .dsnd as it may just be a level issue. Aside from that, edit them as you see fit!
It turns out that it wasn't a problem with the volume of the file at all. I noticed that not only didn't the Roger's snare not work, but I had several "stock" snares that weren't working too. They would register on the brain when I hit the pad, but no sound came out. I decided to put my original 4G card back in the slot to see if maybe those files got screwed up when I copied them over to the 32G card, and lo and behold those same drums wouldn't work from the original card either. I then went into the KIT > VOL section and started playing around with the volume, that made no difference. Then I adjusted the balance and as soon as I moved the position left or right I started hearing the sound. It just wouldn't work in the center. I decided to try the headphones, NOW everything worked. What the problem turned out to be was that I had my amplifer connected to the headphone out on the brain, but I have a MONO amplifier system. I moved the output from headphones to OUT 1 and now everything works!
One thing though, I did try using Sound Forge in XP and Audacity in Ubuntu 11.04 and I was able to increase the volume of the waveform, but when I tried to save it there is no dsnd file extension choice in either program so I tried the "unknown" option in Audacity and typed the filename Rogers.dsnd when asked. It saved the file, it showed up in the brain, but there is no sound output to it. When we adjust a sound like this what do we use when given a choice for sound file type do you know? Do we save them as WAV files and then rename them dsnd?
