Rossum Electro-Music / Triton

Equipped with 3 high-precision VCOs, and by modulating the 1st VCO with the 2nd and 3rd VCOs, it is possible to create waveforms with very complex overtone structures, and to create chords by making the three independent.

Trident is a 100% analog triple oscillator module with unique Zing modulation for dynamic tonal changes.

In a nutshell, Trident is a module with 3 high precision audio VCOs, each with independent CV inputs.

The first oscillator, called the main or "carrier", outputs three waveforms simultaneously. The remaining two oscillators are modulation oscillators, each of which selects and outputs one of three waveforms. The modulation oscillator has a CV symmetry parameter. This allows you to change the duty ratio of the triangle wave to create a smooth transition from a falling sawtooth wave to a rising sawtooth wave, or bend the shaded area of ​​the sawtooth wave left or right to create a more complex waveform. Of course, when selecting a pulse wave, you can also control the pulse width.

Each oscillator can be used independently if desired, but the magic happens when they are used in combination. That magic is Trident's own "Zing Modulation". Each modulation oscillator can modulate each carrier output by an amount controlled by the Zing parameter. Zing modulation is mathematically similar to ring modulation, but syncing the oscillators (when the oscillator's Sync button is on) creates a complex sidetone between the sum and difference frequencies of each oscillator that ring modulation outputs. to a pure harmonic spectrum. Whether you use the modulation oscillator's frequency modulation or waveshape modulation at this time, the sound will change dynamically and dramatically.

If the Modulation Oscillator is set to follow the Carrier Oscillator, the waveform will remain constant as the carrier frequency changes. The harmonic structure in this case is determined by the Modulation Oscillator settings and the CV modulation. If instead the modulation oscillator does not follow the carrier oscillator, some of the harmonic structure will change with respect to the frequency of the carrier.

Whether using Trident's own synced modulation feature or simply as three excellent wide-range analog oscillators, Trident produces a unique sound with great variety.

The main features of Trident are:

Three high-precision analog oscillators with 20Hz-20kHz tuning range and 0.01Hz-25kHz modulation range, with 1V/Octave input.
Main Carrier Oscillator: Triangle, sawtooth, and pulse waves can be used simultaneously. Exponential and linear modulation, pulse width modulation. Equipped with hard sync input.
Modulation Oscillator 1: Selectable from triangle, sawtooth, and pulse waves. Exponential frequency modulation and variable symmetry/symmetry modulation, variable Zing level and Zing level modulation.

Modulation Oscillator 2: Selectable from triangle, sawtooth, and pulse waves. Exponential frequency modulation and variable symmetry/symmetry modulation, variable Zing level and Zing level modulation, variable phase/phase modulation.
Both modulation oscillators can be independently synced to the main carrier oscillator and tracked to the main carrier oscillator.
Like all Rossum Electro-Music modules, the Trident is ruggedly built with thick aluminum panels, solid aluminum knobs and high quality components.
