SigmaTizm is a virtual additive synthesizer instrument 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 program and hardware is required to run it. It should run on any windows PC created within the last 5 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.

SigmaTizm Features:
1. Notes can be played using the computer keyboard and mouse.
2. Can be used as a controller of external MIDI.
3. Control via external MIDI device.
4. Additive synthesis engine with 128 harmonic oscillators.
5. Allows detailed point-and-click editing of harmonics.
6. User-configurable vibrato LFO with multiple waveforms.
7. Adjustable ADSR envelope settings.
8. 7-octave keyboard.
9. Separate attack and sustain harmonics for changing sound timbres.
10. Pitch wheel control lets you 'bend' notes up or down in frequency.
11. Click-and-drag to modify harmonics while sound is playing for interesting sound morphs.
12. Selection of sound output devices using ASIO, MME, or DirectSound drivers.
