Flanger - Arturia KORG MS-20 V User Manual

7.4.14. BL-20 Flanger
The BL-20 Flanger is based on the sound of Arturia's Flanger BL-20 plug-in, which is in turn
based on the sound of a rare but beautiful-sounding hardware flanger from the 1970s. It
doesn't provide all of the BL-20's capabilities, but it still sounds amazing!
RATE is the speed of the LFO that varies the delay time. It can be set without sync
•
or with different types of sync, as explained in
or 1/32 bar to 8 bars)
DEPTH sets how much the internal LFO modulates the delay time. (0.00 to 1.00)
•
DELAY is the length of the basic delay, which is modulated by the LFO and
•
spread out by the Depth knob. (0.00 to 1.00)
FEEDBACK controls the amount of delayed sound fed back into the input to be
•
delayed again. Unlike chorus, where feedback is an unusual added control that's
best used sparingly, Feedback on a flanger is essential to creating its distinctive
resonant timbre. (0.00 to 0/990)
WIDE: This button flips the LFO modulation in the right channel, making the
•
flange sound wider and more three-dimensional... but beware of summing the
two sides to mono, or the flanging will cancel itself out!
MONO INPUT: This switch selects whether the circuit's input is mono or stereo.
