Software Samplers
In the last 10 years the increases in computer power and memory capacity have made it possible to develop software applications that provide the same capabilities as hardware-based units. These are typically produced as plug in instruments - for example, using the VST system. Some such samplers provide relatively simple sample playback facilities, requiring the user to turn to other software for such tasks as sample editing, sample recording, and DSP effects, while others provide features beyond those offered by rack-mounted units.
