CF-101 Chorus/Flanger
The CF-101 is a combined chorus and flanger effect. It adds depth and move-
ment to the sound by adding a short modulated delay to the audio signal. The
delayed signal is then mixed with the original (either in the effect device or man-
ually by you - see below). The CF-101 can be used as an insert or send effect.
Parameters
CV Inputs
The following CV inputs are available on the back panel of the device:
D Delay CV.
Allows you to control the delay time from another device. This may give best
results if you turn off the LFO modulation in the device (turn LFO Mod
Amount to zero). For example, by controlling the delay parameter from a Ma-
trix, you can create “stepped flanger” effects, in sync with the tempo.
✪ If you use the Delay CV input for “playing” the feedback tone, note
that a higher delay value gives a lower pitch.
D Rate CV.
Lets you control the rate of the modulating LFO from another device.
About Stereo and Mono connections
The CF-101 can be connected using mono or stereo inputs, as shown by the
graphs on the back panel. Note the following:
D A “moving” stereo effect is only obtained when you use a mono in-
put and stereo outputs.
With a stereo input, the two sides are processed in parallel, maintaining the
stereo image of the original sound.
D When you are using a mono input and stereo outputs, there will
only be a stereo effect if the internal LFO is used.
If you turn LFO Mod Amount to zero, both stereo outputs will carry the same
signal (mono). This is because the “fake stereo” effect is produced by invert-
ing the modulation for one of the output channels.
Tip: Using the CF-101 as a vibrato effect
The Send mode is intended for when using the CF-101 as a send effect. In this
mode, the device will only output the modulated delay signal - you get the actual
“chorusing” by mixing this signal with the dry, unprocessed signal in the Mixer.
However, if you activate Send mode while using the device as an insert effect,
the result will be a pitch modulated version of the original sound - in short, a vi-
brato effect. Along with a little feedback, this can be used for special effects.
| Parameter | Description
Delay This is a manual control for the delay time used to create the
chorus/flanger effect. Usually, flanger-type effects use fairly short
delay times while chorus-type effects use medium long delays.
Feedback This governs the amount of effect signal fed back to the input,
which in turn affects the intensity and character of the effect.
Turning this to the extreme left (negative feedback) or right (pos-
itive feedback) produces different flanger effects with a pro-
nounced resonance “tone”, while keeping it in between
produces a more gentle chorus effect.
LFO Rate This is the frequency of the LFO modulating the delay time. The
higher the value, the faster the sound will oscillate.
LFO Sync This button lets you activate/deactivate LFO sync. When it is ac-
tivated, the frequency of the LFO is synchronized to the song
tempo, in one of 16 possible time divisions. The LFO Rate knob
is then used for setting the desired time division. Turn the knob
and check the tooltip for an indication of the timedivision.
LFO Mod
Amount
This determines the depth of the LFO modulation, i.e. by how
much the delay time should be modulated. If you set this to 0, the
effect will be “frozen” (most effective if you add some feedback).
Send Mode This determines whether the delayed signal and the dry signal
should be mixed in the effect device or not. If you use CF-101 as
an insert effect, you should turn this off - the device will then out-
put a mix of the dry signal and the modulated delay signal.
If you use the device as a send effect, you should activate Send
mode. Then, the device will only output the modulated delay sig-
nal, allowing you to mix it with the dry signal using the AUX send
controls in the mixer. See also the note below about using the
CF-101 as a vibrato effect!
