1. Now that we understand how the different types of filters function we can look at the Cutoff function Cutoff is used to set the frequency at which the filter s behavior changes relative to the filter type In a lowpass filter the cutoff will set the frequency at which the filter begins to close and allow less and less of the higher frequencies through When the frequencies are high enough past the cutoff point no more sound will be allowed through the filter When the cutoff point is set fully closed full counter clockwise no sound will be allowed through the filter In a highpass filter the opposite applies the cutoff sets the frequency point at which the filter begins to reject sounds that are lower than the cutoff point Sounds far enough below the cutoff point will not be let through the filter at all When the cutoff point is set fully open full clockwise all freguencies will be allowed through the filter In a bandpass or notch filter the cutoff value acts a little but differently it sets the center point of the band or notch which will taper off as the frequencies move away from the cutoff point both in higher or lower frequencies To adjust the cutoff on the FilterBank click on the f dial and while holding the mouse button down move the mouse in a circular motion to rotate the knob you will hear the changes to the audio as you adjust the setting When you are satisfied with the valu2.

20. ng types of effects to use with a filter processor is a gate A gate acts like a door letting sound through when it is open and blocking he sound when it is shut Creative use of gate processing allows the thoughtful musician to create rhythmical pulsing throbbing and strobe like sounds On the left side of the gate is a 16 step sequencer A block represents each step and they are grouped into four segments of four blocks each a perfect relation to the division of quarter notes in a bar of common time A block may be either on or off and simply clicking on each block toggles this state When a block is off it will be a dark color and the sound from the FilterBank will be muted when the sequencer is on this step Obviously when all blocks are turned on the gate will have no effect as sound will never be blocked from leaving the FilterBank by the gate When the sequencer is running a chase light will move across the top of the sequencer showing the user the step that is currently being processed This makes it very easy to select a specific step to either mute or enable to achieve the desired sound Like the delay module the gate effect is most interesting when synchronized to the host sequencer s tempo in fact this is the only way it will work so there is a sync option available Click on the dark blue sync box to select the multiple or division of the host sequencer s tempo and this wi
