6.2 (OVER)DRIVE simulations
Our overdrive simulations offer you a selection of classic stomp box effects.
Just like with the originals, you can set up drive, tone and boost (see (8) B).
The split function () lets you set up an independent crossover (pre distortion
pedal). This crossover lets the high frequencies pass through without distortion.
(left position = off (bypass)/left to right: 41 - 600 Hz). The illustration displays
the frequency range.

6.3 Post-amp effects
The post-amp effects described in the following paragraphs are located post amp
and cabinet simulations in the signal chain. An integrated crossover determines
at what frequency the effects start working and regulates the bass information
when the unit is used without effects. The cut-off frequency of this 18 dB/octave
Butterworth crossover is regulated in EDIT mode under X-OVER. The display
shows the frequency divided by factor 10. Adjustments are made by using the
bank UP/DOWN keys. If the display shows “-”, the crossover is not activated and
the complete signal is affected by the effects. When, for example, “8” is shown
in the display, this means that frequencies under 80 Hz remain unaffected by
the effects.
Volume balance between the high pass and the low pass can be adjusted when
you are setting up the crossover settings by using the EFFECTS control (all the way
to the left = low pass signal only, all the way to the right = high pass signal only).
6.3.1 Reverb and delay algorithms
DELAY+CHORUS: This algorithm combines a delay and the ever-popular
chorus effect.
ST. DELAY: A delay of the input signal. Different tempo settings enable you to
produce interesting delay effects. This way, you can quickly create repititions
particularly with “slapping” that wouldn’t even be possible without a delay.
DELAY/LOOP: This function allows you to jam along with your own signal.
To do that, record with the delay/loop effect a short sequence (max. 15.36 sec.).
This sequence can be played back in an endless loop.
You can for example use this loop as a foundation for your melody and improvise
around it. To record this sequence via MIDI, send the respective MIDI controller
(see chapter 10 ). When you use this function without MIDI, the delay can last a
maximum of 1023 msecs.
REVERB: The reverb is still the most important effect in a mixdown or during a
live event. A reverb is used to add ambience to an otherwise “dry” sound.
AMBIENCE: This effect simulates a room without reflexions.
6.3.2 Modulation effects
PHASER: The phaser functions according to the principle that a second,
phase-shifted signal is added to the original signal. This way, the signal
seems thicker and livelier. This effect was originally used for guitar sounds
and keyboards. In the ’70s, it started being used for other instruments as well
(e. g. electric piano and electric bass).
FLANGER: A flanger modulates the tone pitch of a signal upwards and
downwards at a constant tempo.
(STEREO) CHORUS: This effect subtly detunes the original signal. This way,
a pleasant effect is created in combination with a tone pitch variation. This effect
is particularly well-suited to lend a warm characteristic to the bass sound.
Additionally, when “popping” occurs, it can make the tone sound less intrusive
and harsh.
