Effects and effect plug-ins 135
After any possible compression, Drive provides the option to take the bass sound to
the next level. Saturating the signal takes place depending on the frequency: In spite
of a possibly high level of distortion, the basses remain relatively clean and contoured.
The equalization stage offers 4 frequency ranges, whereby the two mid bands are
variable. The final master volume controller specifies the volume of the final stage. As
with the guitar amp, the end tubes are also engaged in this case as much as remains
sensible.
Rack effects (FX1/FX2)
There are effects that don't always work well before the amp, e.g. reverb or delay,
especially when they are distorted. Normally, these effects are better placed at the
end of the signal chain.
For final processing and enriching, we offer two separate studio-quality effects units
just like real 19" rack devices.
Many algorithms create a stereo signal. Take care that the sequencer track operates
the duct in "stereo" mode.
Effects units may be selectively operated one behind the other (serial) or parallel.
Switching may be changed via the mode switch.
The following algorithms & effects are available:
• Mono delay (msec & tempo sync): Possibly a simple delay with free selection of
delay time or synched to the sequencer tempo with a musical raster. In case of
high feedback values, a reduction of the damping frequency is required to provide
naturalness to echoes.
• Stereo delay (msec & tempo sync): Like mono delay; features two models.
Repetitions may take place on separate channels (feedback controller to the right:
dual delay) or in ping-pong mode (controller to the left), whereby the signal
alternates between the sides.
• Chorus: Produces a typical "floating/shimmering sound" by modulated detuning
of a signal to "thicken up" its sound or spread it across the stereo field. Detuning
is achieved by a short delay, the length of which can be varied by the modulation.
This produces the so-called "Doppler" effect and broadens the signal.
• Flanger: Algorithmically similar to chorus, but different in that the delay time is
significantly lower and delay works with repetitions (feedback). A flanger sounds
more "cutting" and up-front than a chorus.
• Phaser: A modulation effect just like chorus & flanger, but in this case no
detuning takes place. Filter components periodically alter the signal's "phase
response" (principle of the "phase shifter"). Characteristic notches are produced
in the frequency spectrum response (comb filter effects).
