The additive synthesizer, Addictive Synth, is nearly a year old and is still one of my favorite synths on the iPad. This is absolutely the first app I turn to when I want to make some aggressive sounds. I am really excited to hear that VirSyn is getting ready to release version 2, which will be adding even more bite to this baby's harmonic teeth.
The new version brings a "Spectral Noise Generator", which sounds awesome, but they don't provide many details on what the fuck that actually means. From watching their video, it looks like a noise oscilator that is following the harmonic spectrum of the pitched oscilators. This allows all of the morphing goodness to play with the noise generator, which keeps an otherwise chaotic mess in sync. That's just my guess though, watch the video below to see whatever it is in action!
Put on some headphones, this has some nice stuff going on the stereo spectrum too.
