Chapter 12 Retro Synth 228
Retro Synth amp and eect controls
Retro Synth’s Amp controls set the overall volume. You can also mix a sine wave directly into
the output stage, which thickens the sound. You can make the sound richer with Retro Synth’s
integrated Chorus eect or add a sweeping, metallic character with the Flanger eect. If you’re
new to synthesizers and the concepts behind amp controls, see Synthesizer basics overview.

Amp parameters
•
Volume knob: Rotate to set Retro Synth’s overall output level.
•
Sine Level knob: Rotate to mix a sine wave at the frequency of oscillator 1 (Shape 1) directly
into Retro Synth’s output stage. This sine signal is not processed by the lter.
Eect parameters
•
On/o button: Turns the eect section on or o.
•
Eect Type pop-up menu: Choose either the Chorus or Flanger eect.
•
The Chorus eect is based on a delay line, the output of which is mixed with the original,
dry signal. The short delay time is modulated periodically, resulting in pitch deviations.
The modulated deviations, in conjunction with the original signal’s pitch, produce the
chorus eect.
•
The Flanger eect works in a similar fashion to the chorus, but with even shorter delay
times. The output signal is fed back into the input of the delay line. This feedback results in
the creation of harmonic resonances that cyclically move through the frequency spectrum,
resulting in a sweeping, metallic sound.
•
Mix knob: Rotate to set the balance between the original and eect signals. High values result
in stronger eect processing.
•
Rate knob: Rotate to set the modulation speed.
Tip: Use your host application eects if you need more precise control of chorus and anging or
want to use both eects simultaneously.
