Been a user of SliceX in FL Studio for a while. What makes it so powerful is the ability to adjust and modify the shape of the curve for many properties like attack, decay, sustain, release, volume, panning. Would really love is serato sample had this feature. For example, I like to create pseudo side chaining effect, per pad, by creating a steep curve on the attack envelope. This allows me to have multiple versions of a chop. One with instant start, and another with a sidechaining effect.
