Waveforms Combined with Non-linear Functions
14-47
You can also follow a PWM algorithm block with SHAPER, since SHAPERÕs output is affected
by the DC level of the signal.
The parameters on the PWM control input page affect the DC offset of the signal, in terms of
the percentage of shift from no offset to maximum offset. At a value of 0%, there is an offset
positive full scale. At 100%, the offset is negative full scale, and at 50%, there is no offset.
A typical control conÞguration for PWM has the Coarse Adjust set to 50%, an LFO assigned to
Src1, and Src1Õs Depth parameter set to a value of 25%.
The page below shows the PWM function in the F1 block, but it can appear in other blocks as
well.

The six functions in this category do one of two things: they combine samples and waveforms
with a non-linear DSP function, or they use a waveform or sample as inputs to drive non-linear
functions.
Added Sawtooth Wave with Non-linearity (SW+DST)
This function starts by adding a sawtooth wave to the layerÕs sample input. When the input
signal from the sample is added to the sawtooth, the signal may exceed full scale, so a
wraparound function similar to WRAP is performed. The result is then squared to remove any
