dawdreamer.SamplerProcessor

class dawdreamer.SamplerProcessor

The Sampler Processor works like a basic Sampler instrument. It takes a typically short audio sample and can play it back at different pitches and speeds. It has parameters for an ADSR envelope controlling the amplitude and another for controlling a low-pass filter cutoff. Unlike a VST, the parameters don’t need to be between 0 and 1. For example, you can set an envelope attack parameter to 50 to represent 50 milliseconds.
