CF-101 Chorus/Flanger
The CF-101 is a combined chorus and flanger effect. It adds depth and
movement to the sound by adding a short modulated delay to the audio sig-
nal. The delayed signal is then mixed with the original (either in the effect de-
vice, or manually by you - see below). The CF-101 can be used as an insert
effect or a send effect.
Parameters
CV Inputs
The following CV inputs are available on the back panel of the device:
➜ 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 Matrix, 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.
➜ 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:
➜ 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.
➜ 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 inverting 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 - the actual
“chorusing” is obtained 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 ef-
fect, the result will be a pitch modulated version of the original sound - in
short, a vibrato effect. Along with a little feedback, this can be used for spe-
cial effects.

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 me-
dium long delay times.
Feedback This governs the amount of effect signal fed back to the in-
put, which in turn affects the intensity and character of the
effect. Turning this to the extreme left (negative feedback)
or right (positive feedback) produces different flanger ef-
fects with a pronounced 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 Mod
Amount
This determines the depth of the LFO modulation, i.e. by
how much the delay time should be modulated.
If you turn this to zero, the effect will be “frozen” (most ef-
fective if you add a little 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 the device as an insert effect, you should turn
this off. The device will then output 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 modu-
lated delay signal, allowing you to mix it with the dry signal
using the AUX send controls in the mixer.
