Bold, Timeless Sound and Popular Prophet-6/OB-6 Form Factor
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.
The Trigon-6 features three newly-designed, discrete voltage-controlled oscillators per voice, with simultaneously selectable waveshapes (triangle, sawtooth, reverse sawtooth, and variable-width pulse). The 2- and 4-pole ladder filter design with feedback and drive puts Sequential's own stamp on the classic transistor ladder filter sound that has proven its appeal since the dawn of the synth era. Analog voltage-controlled amplifiers complete the analog signal path.
The Trigon-6 takes inspiration from its acclaimed stablemates, the Prophet-6 and OB-6, borrowing their form factor and easy-to-navigate knob-per-fuction panel design. Also present is the much-loved Poly Mod section, also with enhancements. 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, low-pass filter cutoff, and feedback. Another welcome reprise is Unison mode, which features configurable voice count (1-6 voices) and key modes.
The knob-per-function front panel is free of menu-diving, offering immediate access to virtually all parameters. Toggling off the Preset switch enables live panel mode, in which the sound of the instrument switches to the current settings of its knobs and switches.
A dual effects section provides studio-quality reverbs, delays (including modeled digital and analog types), chorus, flanger, phase shifter, and ring modulation. While the effects themselves are digital, with 24-bit, 48 kHz resolution, a true bypass maintains a full analog signal path. An independent stereo distortion is also provided and is 100% analog.
Additionally, the Trigon-6 features a multimode arpeggiator and a polyphonic step sequencer with up to 64 steps (and up to 6 notes per step) plus rests. It allows polyphonic keyboard input and can sync to external MIDI clock. The full-size, four-octave, premium, Fatar semi-weighted keyboard is velocity and aftertouch sensitive.
