Trigon-6 Polyphonic Analog Keyboard

The Trigon-6 was the last synthesizer that Dave Smith, Sequential's legendary founder, contributed to before his passing in 2024, making it a poignant final statement from one of analog synthesis's greatest architects. It represents Sequential's answer to the question of what a modern three-oscillator polysynth should sound like in an era where most manufacturers have moved toward two-oscillator designs.

This is a full-featured six-voice polyphonic instrument built around three discrete voltage-controlled oscillators per voice, each capable of producing triangle, sawtooth, reverse sawtooth, and variable-width pulse waves simultaneously. The heart of the sound is a switchable two or four-pole resonant ladder filter per voice with feedback and drive controls, allowing you to push the filter into self-oscillation and dial in anything from smooth and creamy to aggressive and punchy. You get two four-stage envelope generators for shaping amplitude and filter contour, plus an LFO with five waveforms that can modulate oscillator pitch, pulse width, filter cutoff, or overall amplitude. The semi-weighted four-octave keyboard includes velocity and aftertouch sensitivity, giving you expressive control over dynamics and modulation in real time.

The Trigon-6 comes loaded with both analog and digital character. There's a stereo analog distortion stage for adding grit and presence, plus dual 24-bit digital effects running at 48kHz including reverb, delay, chorus, flanger, phase shifter, and ring modulation. A true bypass switch lets you remove the digital effects entirely and work with a purely analog signal path if you prefer. The sequencer holds up to 64 steps with full polyphonic support, while the arpeggiator offers multiple modes and octave ranges for performance flexibility. You also get a polyphonic step sequencer, poly mod routing for advanced sound design, and a vintage knob that adds subtle voice variation across the six voices for a more organic, slightly detuned character.

The instrument ships with 1000 presets—500 factory sounds and 500 user slots organized into ten banks—giving you a solid foundation of classic basses, leads, and pads to build from.
