When starting up the software, the bit One HD Virtuoso offers
Butterworth
with 12 dB/oct slope as default slope. By changing the
slope, the change will be applied only to the channel you are working on.
Eg.:
if you are adjusting the Front Woofer, the change will affect only that channel (right and left, if linked).
If you selected Band Pass as filter type, the slope will be applied to both hi-pass and low-pass. With the Band
Pass filter type the filter slopes can be unbound.
