FXAlg #910: 3 Band Shaper
3-band shaper
Allocation Units:
2
The 3 Band Shaper non-destructively splits the input signal into 3 separate bands using 1 pole (6dB/oct) filters, and
applies a VAST-type shaper to each band separately. Refer to the
K2500 Performance Guide
for an overview of VAST
shaping. The cutoff frequencies for these filters are controlled with the CrossOver1 and CrossOver2 parameters. The
low band contains frequencies from 0 Hz (dc) to the lower of the two CrossOver settings. The mid band contains
frequencies between the 2 selected frequencies, and the hi band contains those from the higher of the two CrossOver
settings up to 24kHz.
Each frequency band has an enable switch for instantly bypassing any processing for that band, and a Mix control
for adjusting the level of each band that is mixed at the output. negative Mix values polarity-invert that band. The
shaper Amt controls provide the same type of shaping as VAST shapers, but can go to 6.00x.
Parameters:

PAGE 2
In/Out
When set to ÒInÓ the effect is active; when set to ÒOutÓ the effect is bypassed.
Out Gain
The overall gain or amplitude at the output of the effect.
CrossOver1
Adjusts one of the -6dB crossover points at which the input signal will be divided into
the high, mid and low bands.
CrossOver2
Adjusts the other -6dB crossover points at which the input signal will be divided into the
high, mid and low bands.
Lo Enable, Mid Enable, Hi Enable
Turns processing for each band on or off. Turning each of the 3 bands Off
results in a dry output signal.
Lo Amt, Mid Amt, Hi Amt
Adjusts the shaper intensity for each band.
Lo Mix, Mid Mix, Hi Mix
Adjusts the level that each band is summed together as the wet signal. Negative
values polarity-invert the particular bands signal.
