Picture 32: Comb – Filter Type

So, as with all other filter types, the Comb filter is controlled with two parameters:

• Cutoff controls the delay length.

• Resonance controls the feedback depth.

Now, what sound can a comb filter produce? Here are some examples:

The Comb filter as Chorus

This is the most basic way to use the Comb filter. A Chorus in fact is made of one or several Comb

filters so it is an easy task to set it up manually.

☞ To set up the Comb filter to produce a Chorus:

1. Select the Comb+ filter type for the desired filter.

2. Set Cutoff to a medium value.

3. Set Resonance, Drive, Keytrack and any other modulation to 0.

4. Select an LFO as Cutoff Mod Source.

5. Set Cutoff Mod to a medium positive or negative amount.

6. Adjust the LFO to generate a slow triangle oscillation.

7. Fine tune Cutoff, Cutoff Mod and LFO Speed until you get the desired Chorus effect.

 You can also use both filters to create a Chorus and pan them to different stereo positions.

 You can also pan the original i.e. low pass filtered signal to one stereo side and route 50% into

Filter 2 producing a Chorus effect that is panned to the other stereo side.

You might ask why you should use a Comb filter type to produce the Chorus instead of using the FX

section of the Q. Here are some reasons:

• The FX sections are still free for other purposes. Also, in Multi Mode, the Comb filter

works no matter on which Instrument you use it.

• The Comb filter works per voice rather than per Instrument. This means that each voice

has its own Chorus and therefore could generate a different Chorus effect. You can easily
