GBand is a band-pass filter. It removes frequencies from the input that are above or below the specified cut-off points. GBand uses a high- and a low-pass filter in series to remove the unwanted frequencies. It is equivalent to using GHi and GLow, one after the other.

GHi is a resonant high-pass filter. It is used to remove all frequencies from a signal below a given cut-off point. Increasing the resonance of the filter causes the frequencies around the cut-off to be boosted.

GLow is a resonant low-pass filter. It is used to remove all frequencies from a signal above a given cut-off point.

Elysia Niveau Filter
Nveau filter is a specialist in changing the overall sonic character of a signal with ease. It features two comprehensive controllers and is capable of producing convincing results in no time at all. Whenever a classic shelving filter would be too limited and a fully parametric filter would be too much, the niveau filter is the perfect tool.
Its main function is to change the proportions between high and low frequencies. The principle is quite similar to a pair of scales: Dependent on the gain setting around a variable center frequency, the high frequencies are boosted whereas the low frequencies are attenuated (or vice versa) at the same time.
