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.
The Perfect Package
The Trigon-6 has all of the best qualities of Sequwential’s acclaimed Prophet-6 and OB-6 synths — 6-voice polyphony, unrivaled playability, easy programmability, and modest footprint — packed into a four-octave, semi-weighted keyboard with velocity and channel aftertouch. What differentiates it from its siblings is its unmistakable “3-oscillators-through-a ladder-filter” punch. It raises the bar for what the ideal power poly can and should be.
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.
