Razor is based on additive synthesis, with up to 320 partials (individual sine waves). While additive synthesis has a reputation for being a tad 'scientific', Razor is very friendly, presented in the guise of a typical modern synth, with two oscillators, twin filters, and three effects sections: Dissonance, Stereo and Dynamics.
You’ll find that ripping DnB/dubstep noises are shockingly easy to dial in, but bumpin' basses and sweet pads/leads are readily had too.
We'll admit that we were initially a tad sceptical about Razor, it being 'just' a Reaktor-based affair and entirely additive. However, it actually makes additive synthesis not just palatable but downright desirable.45 Stars
