4.3c Chorus Parameters
Stereo chorusing thickens up a sound by delaying the sound by a small amount
(generally less than 25 milliseconds), changing the delayed sound's pitch periodically
with LFO modulation, then mixing the delayed and straight signals together. The
various phase cancellations and additions that occur as the delayed and straight
signals interact produce chorusing.
With many synthesizers, the recommended way to chorus is layering two identical
sounds together and slightly detuning them. However, this cuts the available
polyphony in half since two notes are layered on one key. The DPM V3 provides two
chorusing methods that don't use up more voices in addition to the Effect 1 or 2
chorus effect, you can also assign the same sound to OSC1 and 2 in a voice, and
slightly detune them. On
If you're really wild about detuning, you can use the methods described above and
create a Combi patch with two or more detuned layers.
Also, note that the chorus effect can be used for flanging, as described below.
Page 1 Parameters
Delay Seis the initial chorus delay time in 0.5 millisecond increments from 00.5 ms to
25.0 ms. Generally, the range of 12 to 25 ms is ideal for chorusing; 00.5 ms to 12 ms
is a good range for flanging effects.
Rate Sets the periodic modulation rate from 0.0 Hz to 9.9 Hz, in 0.1 Hz increments.
Use slower rates (e.g., 0.3 Hz) for flanging.
Page 2 Parameters
Depth (00-99) Varies the modulation amount from 00 (no modulation) to 99 (maximum
modulation). Flanging usually sounds best with maximum modulation, a short delay
time, and a slow modulation rate.
FdBak (00-99) Determines how much of the chorused signal feeds back to the input;
more feedback creates a more intense sound.
Page 3 Parameters
Mix Controls the mix of dry and processed (wet) signals. The variable mix parameter
shows the ratio between dry and wet signals, as well as DRY for all-dry and WET for
all-wet signals. The most intense chorusing and flanging effects occur with a 50:50 mix
of dry to wet. Tilting the ratio toward dry (e.g., >50:50) puts the chorus or flanging ef-
fect more in the background.
