bristol 0.60.11 Synthesizer emulator
Bristol is an emulation package for a number of different
classic synthesizers including additive and subtractive and a few organs. The application consists of the engine, which is called bristol, and its own GUI library called brighton that represents all the emulations. There are currently more than twenty different emulations; each does sound different although the author maintains that the quality and accuracy of each emulation is subjective.
