A hybrid instrument based on physical modelling and granular synthesis.
It starts with the oscillators, which give a choice of five modes, each with four oscillators per voice (hence the name Tetrad). In the Macro view, you can change the main oscillator waveshape, and apply frequency modulation. Oscillators can be tuned in various ways according to the chosen mode, from basic intervals to diatonic inversions. An ADSR provides initial amplitude shaping before heading down to the mixer. There is also a Sidechain audio option, bypassing the oscillators and allowing any signal to be used.
A 4×4 Matrix Mixer blends the four inputs onto four busses. Next is Quad Amplitude Modulation with Depth, Shape and Rate, which works well into the audio range, and Phase set individually per bus. In Tetrad’s Quad Granulator, the signal is split into grains that are replayed in different ways. You can affect the grains’ window shape, Size, Pitch, and change the Feedback of the granulator. Finally this feeds the Plates through a preamp with overdrive.
Tetrad is like no other synth you’ve ever used. Developed in collaboration with composer and transmedia artist Gadi Sassoon, the plugin takes four oscillators, routes them in combination through a Quad AM processor that works like a pseudo-sequencer, a specifically tailored Granulator, and four physically modelled plate resonators.
Inspired by Gadi’s sculpture-based synth installation, as heard on the album Modes of Vibration, Tetrad was originally devised as a complement to the slashed plates and sound generators of the experimental setup, but has grown into a plugin instrument that puts the capabilities of the installation into a single piece of software in a DAW.
Tetrad encourages you to think in a different way about creating sound, and its modulation matrix widens the scope even further. Here, you can route sources to ten destinations from a choice of over 45. Each routing has an amount to set its depth.
Sources include eight LFOs, MIDI values and MPE dimensions. Envelopes include the synth’s main ADSR as well as some envelope-following signals, which are derived from the AM and Granulator levels, making these sources self-modulatable. Each source has a visual indicator of its value to help understand its effects on the signal.
MPE Velocity, Slide, Pressure and Glide are available as modulation sources for the full MPE experience. In MPE mode, pitchbend and glide are available continuously across the full range of MIDI notes.
