Yeah, I remember that from what you told me last time, when I was asking you why I was getting a popping sound with a bass sample I made. So, because of that, I started using the envelopes and applied sharp fade outs to kill the sound quickly, as opposed to using Note Off. With this, I thought I was doing that as well. In fact, it's not the attack that causes the popping; the popping occurs during the looping section of the envelope. I click the Note Test button to start the sound, the sound reaches the loop just fine (no popping). I click it again to turn it off, and the sound pops as it fades.
As for the Resampling thing: oh shoot. I forgot I changed that. That was set to none; I started changing that and the sampling rate in hopes to remove the popping I was hearing.
