Spectral isn't an iZotope Iris-style spectral synth, but instead one built on an additive architecture, fronted by a subtractive interface, making it easy to use but capable of potentially more interesting sounds than a virtual analogue.
A Spectral patch starts with four oscillator sections, each with its own filter and amp/filter envelopes. Further modulation is on tap in the shape of three more envelopes and five LFOs, assignable in the modulation matrix.
There are effects, too, and Spectral comes with a library of over 850 presets divided up into a broad set of categories. The overarching flavour is very crisp and upfront - bouncy bass sounds, bell-like pads and keys, and even a serviceable set of synthetic drums. However, the synth is most at home producing evolving and textural sounds
It won't be for everyone, but if the idea of hand-designing unique textures right down to the raw oscillator level appeals, with its friendly interface, easy learning curve and superb, characterful sound, Spectral could well be the synth for you.4 Stars
