Re: Alesis Sample Pad
Not sure why some .wavs will play, and others won't. Best guess is that since the files need to be mono, and the fx are probably stereo, the program saved them as stereo. Make sure you save in a mono format.
Also make sure the sample rate is common: 44.1, 32, 22,050, 16, 11,025, or 8khz. and obviously the total samples can't exceed about 14mb, but I doubt those are the problem here.
One more thought, I had an SD card that wouldn't work in the unit. Don't know why, it read fine on both Mac & PC. Do your working sounds come from one card, and the non-working sounds come from another? Always use a known compatible card.
