Doepfer

The announced quadrature/thru zero oscillator is based on a "real"
sine/cosine core and will be able to generate perfect sine waves. At the
moment we are about to try different temperature compensated exponential
generators for the oscillator to obtain a frequency range as wide as
possible.
