✻ 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 Chorus instead of using the FX section of the
Blofeld. Here are some reasons:
• The FX sections remain 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 hear this when you
change LFO Keytrack or Filter Keytrack. Now,
each voice sounds with a different Chorus speed
or frequency.
• You have full control over MIDI of all parameters
that make up the Chorus effect, by using Control
messages.
The Comb filter as a Flanger
A Flanger is almost the same as a Chorus. The only
difference is that it has feedback circuitry to change the
depth of the Flanger effect.
☞
To set up the Comb filter to produce a Flanger:
1. Adjust the filter as described in the Chorus
paragraph above.
2. Turn up Resonance to create the typical
Flanger sound.
3. Gradually lower LFO Speed to create slow
Flanger sweeps.
4. Select either Comb+ or Comb- to change the
character of the Flanger.
✻ Set up Mod Source to Modwheel to change the
Flanger effect manually.
✻ Use the Filter Envelope with positive or negative
amount to create a “one time sweep” that is
triggered at Note On.
✻ Use Filter Keytrack with an amount of 100% to
create really different flangings depending on the
Note you play.
