Synth objects 247
Stereo delay (tempo sync / millisec.)
Stereophonic repetition, adjustable separately per side
Parameters
• Left / Right: Delay times, synced or free running
• Feedback: In contrast to mono delay, no repetition takes place in the middle
position of the feedback controller. When turned to the left the type of delay is
that of the so-called "ping-pong" variety, i.e. the signal is alternately sent so that
is jumps from one channel to the other. When turned to the right the delay effect
is "dual mono", in which case left and right sides act as two independent time-
delay units.
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.
Parameters
• Time: Delay time in milliseconds. This can be understood as the "base"
modulation which is stretched or compressed by the modulator.
• Rate: Modulation speed
• Depth: Modulation amplitude. Low values modulate only a little, higher values
lead to a clear vibrato.
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.
Parameters
• Rate: Modulation speed
• Feedback: Delay feedback
• Depth: Modulation amplitude
Phaser
A modulation effect just like chorus & flanger, but in this case no detuning takes
placed. Filter components periodically alter the signal's "phase response" (principle of
the "phase shifter"). Characteristic notches are produced in the frequency spectrum
response to create so-called "comb filter effects". The phaser effect is suitable for
pads and "psychedelic" sounds.
