of each period of the waveform of the master oscillator which therefore acts as a master clock as

shown in Figure 9.

The perceived pitch of the ﬁnal output of the oscillator module is the same as that of the master

oscillator while the frequency of the slave or synced oscillator only affects the harmonic content

and therefore the timbre of the resulting signal. The Shape control applies to the shape of the

slave oscillator. The shape of the oscillation of the master is indeed irrelevant as it is only used to

generate a master clock signal.

In hard sync mode, the frequency of the master oscillator is determined by the settings of the

Octave, Semi and Key controls. The frequency of the slave oscillator is adjusted using the Tune

knob and its value is presented as a ratio between the frequency of the slave and that of the master

oscillator. It can take values between 1 and 20 and can be modulated by the ramp signal of the

oscillator envelope using the Ramp knob and the output from the LFO module.

Note that in sync mode, the sub-oscillator knob is not available.
