With ZeroVector White Noise, previously known for more experimental additive synths, has jumped to the head of the pack with this excellent subtractive. ZeroVector is a fairly conventional subtractive synth architecturally but stands out with a lush, rich & sweet sound and a distinctive sonic personality.
ZV's *huge* unison mode is the best I've heard in any softsynth. It's simultaneously big and very clear, unlike the noisy unison modes on a lot of other softsynths. Combined with the oscillator cloning feature ZV sounds bigger than anything except perhaps Vanguard, and it sounds a lot cleaner than Vanguard can.
ZV also has an excellent filter. Comparable even to impOSCar and Albino for a warm analogue sound with a very musical resonance. The vector pad makes it possible to make some very dynamic and interesting sounds, great for pads and ambient textures. The effects section is pretty complete and easy to use.
My only complaints are that the UI is a little hard to read quickly and that the vector pad needs a loop mode. Replacing the knob graphics with something more obviously directional controls would help a lot. With these changes and White Noise Additive-style midi learn this would be an easy ten. As it is now it's a very, very solid 9.
