X Filter is a Key filter usually used for side chains but this filter is very musical with very smooth curves. This is superb for getting elements to fit into the mix! Think of x filter as being in between a filter and a shelf eq.
Keeping in the tradition of combo programs the High and low cut are combined in to one instance allowing quick tweaking when the inspiration hits!
As usual I’ve sampled natively in 4 sample rates- 44.1khz 48khz 88.2khz 96khz Normal and high quality presets are available in the set as well as stereo and mono presets!
As Enrique says.... Also if you use say my scs treble and bass adjust the input by ear . The preamp was sampled with a bit more of higher level than a preamp of this sort would see as it's instrument line.
