Trigon-6 Desktop Module

The Sequential Trigon-6 desktop module delivers the same massive sound and hands-on sonic control as the Trigon-6 Keyboard. It features the same pure analog signal path with discrete oscillators and filters, and the same high-quality digital effects. It also has the same intuitive layout with full-sized knobs and switches that make it quick and easy to shape new sounds.

The Trigon-6 module sounds huge — just like the keyboard, because it is the same six voice polyphonic instrument, just in a smaller form factor. And if you want even more polyphony, you can use the poly chain feature to link any two Trigon-6s for a stunning twelve-voice synth!

A Sound That’s Bold and Familiar

The Trigon-6 is Sequential’s polyphonic take on the classic, thick and creamy, 3-oscillator-plus-ladder-filter analog sound that defined the dawn of the synth era. It’s a sound that bridges genres and styles — now refined and redefined with Sequential’s own modern imprint.

All-New Filter and Oscillator Design

At the heart of the Trigon-6 sound are three newly designed voltage-controlled oscillators (with triangle, saw, and pulse waves) and an enhanced version of the ladder filter that Sequential created for its Pro 3 mono synth. The switchable 2/4 pole resonant filter design has dedicated drive and feedback controls that make it effortless to go from bold and crunchy to silky and smooth with a simple knob turn.

Rounding Out The Picture

Naturally, the Trigon-6 has the full complement of Sequential’s ”must-have” sound-sculpting features including super snappy envelopes, a syncable LFO with multiple waveforms and destinations, a polyphonic step sequencer, and an arpeggiator. Best of all, the knob-per-function front panel of the Trigon-6 puts these conttrols at your fingertips. And the ready-made palette of 500 factory and 500 user presets provides classic basses, leads, and pads to jump start any project.

More Power Features

Also present is Sequential’s classic Poly Mod, with enhancements for creative sound design. Modulation sources are filter envelope and oscillator 3 (both with bi-polar control). Destinations include oscillator 1, 2, and 3 frequency, oscillator 1, 2, and 3 pulse width, filter cutoff, and feedback. Unison mode is here as well, featuring configurable voice count (1-6 voices for up to 18 simultaneous oscillators) and key modes.

Dual Effects

The dual effects section provides studio-quality reverbs, delays (standard and BBD), chorus, flanger, phaser, and ring modulator. The independent stereo distortion effect adds on-demand aggression and is 100% analog.

Adjustable Vintage Character

Finally, to give even more classic organic warmth to an already classic synth, there’s the Vintage Knob, which adds voice-to-voice variations in calibration and component behavior. Vintage behavior is adjustable from subtle to extreme to emulate the stability of a perfect modern instrument or a time-worn relic.

More Than the Sum of Its Parts

Add all of this up and the Trigon-6 represents a modern synth workhorse with a bold, versatile, 3-oscillator ladder filter-based sound. It builds on the past, refines the present, and redefines the future for accessibility, portability, and playability in an analog poly synth.
