DSP Functions
The DSP Functions
SINE, Sawtooth (SAW), SQUARE
There's only one parameter on this control-input page that may still be unfamiliar to you:
Fine Hz. This is discussed on page 6-27. It can tune the pitch of the waveform in terms of its
actual frequency in Hertz, as opposed to the usual method of tuning by key names. The
advantage to using the Fine Hz parameter is that you can maintain constant beat frequencies
across much of the keyboard when you have a program with slightly detuned multiple layers
(or multiple waveforms in one layer).

If you want the waveform to play with standard twelve-tone octaves, set the KeyTrk parameter
to 100 cents per key. Different values for KeyTrk will result in nonstandard tunings.
Low Frequency Waveforms: Sine (LF SIN), Sawtooth (LF SAW), Square (LF SQR)
These can be used like the waveforms above, since their frequency ranges are similar, but they're
intended to be used not for their timbres, but for the shape of their waveforms. By using low
frequency values for these waveforms, you're basically getting extra LFOs with very precise
control parameters. They're intended to be used as inputs to drive the DSP functions in the
subsequent algorithm blocks. They're especially useful with the nonlinear DSP functions, such
as xAMP.
The parameters on this page affect the pitch of the low frequency waveform in a slightly
different manner. They're all tied to the value of the Coarse Adjust parameter, so when you're
working with this page, you'll want to set the Coarse Adjust first, then set the values of the other
parameters to modify the initial setting. The Coarse Adjust value is multiplied by the values of
16-40
