SigmaTizm Version 1.1
SigmaTizm is a standalone MIDI-enabled virtual additive synthesizer designed for live play.
Additive synthesis works by using a large number of sine wave oscillators at different frequencies to create complex musical timbres. It is based on the mathematical theories of Joseph Fourier and has been used in the popular Kawai K5000 series of hardware synthesizers. SigmaTizm has 128 harmonic oscillators, allowing it to create rather complex timbres.
No plugin host or additional software and hardware is required to run it. It should run on any windows PC created within the last 7 years. Additive synthesis is fairly CPU-intensive, so playing a large number of notes at once or configuring a large number of harmonics (>64) can cause high CPU usage which can result in sound glitches on slower systems.
To get started, click the folder icon to load a predefined "patch" and press keys on your keyboard or click the keyboard keys with your mouse to play sound. For detailed instructions, click the "?" icon to view the application's built in documentation.
