Critic Reviews

Sequential Trigon-6

soundonsound.com

Dave Smith's final synthesizer, the Trigon-6, delivers a warm, rich analog sound that pays tribute to its creator while offering modern versatility. With three oscillators per voice and a robust filter, it excels in crafting a wide range of tones, from lush pads to punchy leads. However, its four-octave keyboard may frustrate those seeking more playability, and the lack of multitimbrality and a higher-resolution display could limit some users. Despite these drawbacks, the build quality is solid, and the synth's unique capabilities, like polyphonic feedback, make it a compelling choice for sound design. In the end, the Trigon-6 stands as a fitting homage to its late founder, blending nostalgia with innovation, though it may not satisfy everyone’s needs.

Sequential Trigon-6 review | MusicRadar

musicradar.com

The Sequential Trigon-6 synthesizer showcases exceptional design and sound quality, elegantly blending classic and modern features. Its intuitive layout and robust modulation options inspire creativity, making it a joy for sound sculpting. However, it lacks some depth in modulation capabilities compared to its competitors, and its price may deter potential buyers seeking more polyphony. While the preset organization feels arbitrary, the sonic versatility and hands-on controls ultimately deliver a rewarding experience. This synth stands as a fitting tribute to Dave Smith, cementing its legacy as a must-consider for enthusiasts.

Sequential Trigon-6 is Dave Smith’s last love letter to American synth icons

musictech.com

The Sequential Trigon-6 offers a compelling blend of classic American synthesis with modern features, highlighted by its rich-sounding custom oscillators and Moog-style ladder filter. The user-friendly interface and companion app make it accessible for all skill levels, while its build quality is commendable. However, the aftertouch feels overly stiff, and the lack of visual indicators for modulation could hinder some users. Overall, it stands as a fitting tribute to Dave Smith’s legacy, merging nostalgia with innovation, though it may not be perfect for everyone.

The Trigon-6, again another Dave Smith (R.I.P.), has also become one of my favorites. It's much one of the more newer synths they've come up with and it's a similar level of complexity. Again, it's quite a simple synth but one that you can jump in and build and you don't get lost in the complexity.

To be honest, I hate patch diving and I hate, you know, menu diving, and having shortcuts. The synths that are my favorite ones, like those, there is no digital display. It's just, you know, you can do presets and it's just like an old-school LCD watch sort of display, but there's no menu diving, you don't need shortcuts, everything's there. You can just jam and play and you got this real tactile sort of interaction with it. And that's what I look for, to be honest, with hardware synths.
