Claim 0:
1. A digitally controlled oscillator for a synthesizer module, wherein the oscillator comprises:
a digital processing unit configured to generate a first pulse wave at a first output of the processing unit, wherein the first pulse wave is arranged to include pulses at at least two different first frequencies;
a summing circuit;
wherein the first output of the processing unit is connected to the summing circuit, and the summing circuit is arranged to produce a resultant signal based on at least the first pulse wave; and
wherein the resultant signal is arranged to be fed into the linear wave shaper, wherein the linear wave shaper is arranged to produce an output signal, being an electrical audio signal including, as fundamental frequency components thereof, frequency components corresponding to the at least two different first frequencies, at the output of the oscillator based on modifying the resultant signal, wherein the modifying comprises at least integration of the resultant signal.
