sound. It should be obvious that sounds with a richer harmonic structure will be effected in a much more dramatic
way than harmonically starved sounds. Having more notches, i.e. a greater Ônotch-densityÕ, should produce an even
more intense effect. This increase in notch density may be achieved by having a number of modulating delay lines,
all set at the same rate, but different depths. Setting the depths proportionately results in a more pleasing effect.
An often characteristic effect of flanging is the sound of system noise being flanged. Various pieces of analog gear
add noise to the signal, and when this noise passes through a flanger, you can hear the noise ÒwhooshingÓ. In the
K2500, the noise level is very low, and in fact if no sound is being played, there is no noise at all at this point in the
signal chain. To recreate the effect of system noise flanging, white noise may be added to the input of the flanger
signal (Flanger 2 only). Since white noise has a lot of high frequency content and may sound too bright, it may be
tamed with a first-order lowpass filter.
