The Trigon-6 represents Sequential's answer to the classic three-oscillator analog sound, arriving as the company's final design contribution from legendary founder Dave Smith before his passing in 2022. It's a statement piece that takes the DNA of vintage polysynths and rebuilds it with modern engineering and workflow in mind.
At its core, you're getting six voices of pure analog synthesis, each powered by three discrete voltage-controlled oscillators that can generate triangle, sawtooth, reverse sawtooth, and variable-width pulse waves simultaneously. The third oscillator can be disconnected from keyboard tracking and repurposed as a modulation source or LFO, giving you serious flexibility in how you shape sound. A switchable two or four-pole ladder filter per voice handles the low-pass filtering with the ability to self-oscillate, and you can drive it into saturation or back off for smoother character. The Vintage knob adds subtle voice-to-voice variation, letting you dial in anything from pristine modern tone to the kind of natural drift you'd find in a well-loved vintage machine. Hard sync between oscillators one and two opens up those classic metallic and bell-like textures.
Modulation is where things get interesting. You've got dedicated four-stage envelopes for both filter and amp, a five-waveform LFO with sync capability, and aftertouch sensitivity across the keyboard for real-time expression. The Poly Mod system lets you route modulation sources to multiple destinations per voice, and the sequencer handles up to 64 polyphonic steps with six notes per step. An arpeggiator rounds out the sequencing toolkit. On the effects side, there's stereo analog distortion plus dual 24-bit digital effects including reverb, delay, chorus, flanger, phase shifter, and ring modulation, all with true bypass to keep your analog signal path intact when you want it.
The desktop module format measures 22 inches wide and weighs just under 11 pounds, making it a serious contender for studio setups where space matters but power doesn't. You get 1000 presets to work from, a full complement of CV and audio I/O, and the kind of knob-per-function layout that rewards hands-on tweaking.
