Software synthesizer
From Wikipedia, the free encyclopedia
A software synthesizer, also known as a softsynth or virtual instrument is a computer program for digital audio generation. Computer software which can create sounds or music is not new, but advances in processing speed are allowing softsynths to accomplish the same tasks as dedicated hardware. Softsynths can be cheaper and more portable than dedicated hardware, and easier to interface with other music software such as music sequencers.

Dedicated hardware synthesizers can have software as complex as a softsynth. The distinction is that softsynths run on a general purpose computer, usually with a sound card. The advantage to dedicated hardware is that it can be more stable, and also that it often has a user interface that is physical and therefore easier to manipulate during performances. Many softsynths use mathematical algorithms which directly emulate the electronic components and circuitry of the original harware synthesizer. This results in an exceptionally authentic sound, as well as allowing for some of the inconsistencies, such as oscillator drift caused by the thermal sensitivity of the components, to be added.
One common type of softsynth is an emulator. There are a number of very popular synthesizers which are no longer manufactured. While some can be purchased second hand, many are expensive and temperamental. The emulation can even extend to having graphics that model the exact placements of controls. Popular synthesizers such as the Minimoog and Yamaha DX-7 have emulators.
Some softsynths are heavily sample based. Computers have fewer restrictions on memory than dedicated hardware synthesizers. Some of these sample based synthesizers come with sample libraries many gigabytes in size. Some are specifically designed to mimic real world instruments such as pianos. Many sample libraries are available in a common format like WAV files, and can be used with almost any sampler based softsynth.
It's common for recent softsynths to be compatible with technology such as Virtual Studio Technology (VST), which allow other music software to interface with the softsynth. Plug-in technologies include VST, DXi, Motu Audio System (MAS), Audio Units (AU), and Real Time AudioSuite (RTAS).
