Quantize Frequency
Use the Quantize Frequency process to constrain a
sine/triangle/square/saw waveform to specified frequency intervals.
Quantize Frequency has no effect on Left/Right/L+R/Stereo
Selections, Noise signals, or any incoming signals except for
Frequency Modulations from the output of a Pitch Tracker. (In other
words, it can only quantize a frequency if it knows what the
frequency is.)
The Quantize Frequency process is generally used with a source
signal (sine, etc.) that is being frequency modulated by another
signal. Quantize Frequency will look at the current instantaneous
frequency and quantize it to the nearest appropriate value.
For example, if you set the quantization interval to 1 semitone, a
sine wave sweep would be converted into a chromatic scale. If you
set the quantization interval to 2 semitones and frequency modulate
the source waveform with white noise, you get a random series of
notes in the whole-tone scale. Similarly, sweeping a waveform with
a quantization interval of 3 will produce diminished arpeggios; 4
yields augmented arpeggios; 6 gives tritones, and 12 produces
octaves. Fractional values are allowed as well.
DC Offset
Use DC (“direct current”) Offset to offset the source signal level by a
fixed amount. This can be useful in certain specialized cases.
For example, if you want to generate a sine wave that sweeps
between 0% and 100% (instead of –100% to +100%), you can feed a
full-range sine wave through a DC Offset of 100%. The DC Offset is
added to the sine wave, producing a signal that varies between 0
and 200%. Then by setting the modulation or output amplitude to
50%, you get a signal that varies between 0 and 100%.
You can also use DC Offset to cancel out a pre-existing DC offset.
