Six is a streamlined 6-operator FM synthesizer designed to offer deep sound design possibilities through a rich selection of algorithms. It includes 32 DX7-style algorithms alongside 16 four-operator configurations, providing a broad palette for crafting complex tones. Each operator features fine tuning, octave control ranging from -6 to 3, and pulse width adjustments, enabling precise control over the harmonic content. A variety of waveforms such as saw, triangle, pulse, sine, and ramp are available to further shape the sound.

The synth's sound shaping capabilities are enhanced by an 8-stage envelope with four distinct curve types, complete with additional time and level parameters to refine dynamics. A versatile filter section mirrors the envelope's flexibility and offers seven filter types, including multiple lowpass options, highpass, bandpass, and classic 4-pole and 8-pole Moog-style filters. These elements allow for detailed tonal sculpting, from smooth filtering to aggressive sweeps.

Six also features onboard effects such as chorus, phaser, and stereo delay with a cross-feedback option, enriching the sound with spatial and modulation textures. Additional controls like phase modulation and feedback provide further sonic variation. With a powerful randomization function, users can quickly generate new presets, making it ideal for experimentation and inspiration. It comes equipped with 128 presets to jumpstart your music production process.
