> LINK (ENVELOPE AMOUNT, RESONANCE, KEY FOLLOW)
When enabled, Env Amt, Resonance and Key Follow become linked with their counterparts in
filter 2, so that both filters can be adjusted simultaneously.
> KEY BASE
This determines the MIDI note number from which the keyfollow parameter will start to have
an effect. To set the key base, either type in the MIDI note number in the text window, or click
on the button and press a key on your controller keyboard or the onscreen keyboard.
Filter 2
> MODE
Selects the filter type:
> Low Pass:
The most commonly used filter type. Removes frequencies higher than the cut-
off point.
> High Pass:
Removes frequencies lower than the cutoff point.
> Band Pass:
Allows only a narrow band of frequencies through - Resonance determines the
width of the band in this case.
> Band Stop:
The opposite of Band Pass, this filter removes a narrow band of frequencies.
Often referred to as a 'notch' filter, as it effectively cuts a notch in the tonal spectrum. Res-
onance determines the width of the notch.
> CUTOFF
This determines the frequency above or below which filter 2 will come into effect. For
instance in a lowpass filter, frequencies below this point are allowed to pass, and those above
are attenuated according to the slope of the filter.
> RESONANCE
In Low Pass or High Pass modes, this determines the emphasis of those frequencies near to
the cutoff point. As you increase the level it results in a more nasal or 'honking' tone. In Band
Pass and Band Stop modes, increasing the resonance reduces the width of the band.
