Delay Parameters
Time. The amount of time (in milliseconds)
between the source signal and its echo.
The simplest delay effect is a single repeat. A short delay
between 30 and 100 ms can be used to create slap-back echo,
while longer delay times produce a more distant echo.
Delay times that are too short to hear as distinct echoes can
be used to create thickening effects. Whether these echoes
are timed with the tempo is a matter of stylistic choice.
Tap Tempo (TAP). This lets you adjust the delay time to match
the song tempo by tapping it in time to the music.
Time X. The value of the beat (note length) you’re using as a tempo reference.
The basic note value is a quarter note, so for example, if the beats
you’re tapping represent quarter notes in the music, you would set
Time X to 1.00. If they are eighth notes, you would set Time X to 0.50,
half notes would be 2.00, and so on. In this way, you can precisely
synchronize or syncopate the delay echoes to the music in real time.
Note: The Stereo Delay offers two Time X controls. With the Ping
Pong delay, the Pong X parameter serves the same purpose.
Feedback. This produces multiple decaying repeats. Increasing
the feedback value increases the number of echoes, as well as the
resonance that is created as one echo disappears into another.
F_Frequency. Sets the center frequency in Hz for the Filter Delay.
F_Gain. Sets the boost at the center frequency for the Filter Delay.
F_Q. Sets the Q for the Filter Delay, which is the ratio of the
center frequency to the bandwidth. When the center frequency
is constant, the bandwidth is inversely proportional to the
Q, so as you raise the Q, you narrow the bandwidth.
Left-Right (L-R) Spread. This set the width of the stereo image taken
up by the repeats when using a Stereo or Ping Pong delay.
The following list shows the available parameters for different delay types:
Mono Delay: Time (ms), Time X, and Feedback
Filter Delay: Time (ms), Time X, Feedback, F_Frequency, F_Gain, and F_Q
Stereo Delay: Time (ms), Time1 X, Time2 X, Feedback1,
Feedback2, F_Frequency, L-R Spread
Ping Pong Delay: Time (ms), Pong1 X, Pong2 X, Feedback1,
Feedback2, F_Frequency, L-R Spread
