The Trigon-6 Desktop by Sequential is a 6-voice Polyphonic Analog Synthesizer.

The Sequential Trigon-6 Desktop Module delivers the same sound and hands-on sonic control as the Trigon-6 Keyboard. And the same analog signal path with discrete oscillators and filters and digital effects. It also has the same intuitive layout with full-sized knobs and switches.

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 silky and smooth to bold and crunchy with a simple knob turn.

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

Also present is Sequential’s classic Poly Mod. 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.

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.
