Most people have used a sampler to loop and replay a sample. However, many experimental bass producers employ a little-known technique. This is accomplished by varying the start and endpoints of the loops, as well as their overall time. The Sampler may totally randomize the portions of the audio it jumps to by manipulating these settings, resulting in extremely unique sounds.
This approach consists of a few critical steps:
After you've imported your sample, change the sustain mode to looping. This is towards the bottom of the VST, towards the center. Two arrows will be facing each other. Then go to the Modulation window and activate the "Aux" envelope. Set the "Loop Start" and "Loop Length" values for the envelope. This allows the radio commercial scripts to change the looping based on the ADSR parameters you set on the Aux envelope.
