First review here. I've lurked...I've read, but I've never spoken out. I'm not very conversant in the language of synths so I don't know if I can add to the technical stuff already ably supplied by ew and Spe3D. Whatever they said, I agree with!
As a musician, I'm in love. I have a number of different synths and they are each excellent in their own way. Let's put it like this, I'm just beginning to learn to program many of these wonderful synths but with the White Noise Additive, I'm able to stumble around in an intuitive way and make usable sounds really quickly. And these sounds are not hackneyed cliched thangs, either. While all synthesizers make music, this is somehow for me a very musical synthesizer...we just sort of bonded and hit the deck running. Alright, I admit to really enjoy playing in the sandbox of sound and with the Whitenoise Additive it feels like a vast expanse. The sounds cover the gamut from usable bells and pads to the lullabye sung somewhere down the wormhole that's to the right of alpha centurae. The .bmp files also help to make it incredibly flexible.
Because it's additive, I think it has a unique sound and while I don't know additive well enough to know all the differences between White Noise, Cameleon, Vertigo and Adder, I do know that they all seem to have their own je ne sais qua...the Additive though is something that I have been going to alot because it seems so intuitive to work something up from scratch. I'm not too particularly taken by the manual. It's a flash help file. It's an interesting approach and not unhelpful but I'm still 20th century enough to want to hold text in my hand. It has been relatively stable. So far so good.
And besides, I really like the pretty spectrums. Yeah!
