The oscillator section can comprise one of four designs. Mixed, matchedĭiva's structure is pretty standard. u-he says this is the first time such methods have been employed in real-time by a native soft synth.
The algorithms u-he uses are tuned for audio, however: they run in real time, and the components have been carefully matched to produce the desired sound (u-he say that software such as PSpice, while giving correct results, is unable to precisely reproduce the sound of specific componentry).
