6.1.6.6. Digital Delay
With the arrival of affordable digital signal processing (DSP) in the 1980s, a new type of
echo effect was created: the
Digital Delay
, where input audio is converted to digital data,
delayed, converted back to analog, and output. This creates echoes that don't degrade
unless they're externally filtered, but also allows for some neat tricks that an analog delay
can't do.
This is a dual digital delay that operates in stereo. The left and right delays have two controls
each:
Time
: Sets the delay time for that side. Delay time ranges from 9.07ms to 1000ms (1
second). If MIDI Sync is turned on, delay times range from 1/128 note to one bar at the
current tempo.
Feedback
: Adjusts the Feedback amount for that side. Unlike the Analog Delay, the Digital
Delay's Feedback can be set to run away, with each successive echo getting louder and
more distorted. Use with care!
The rest of the controls work on both sides of the delay at once:
Link
: Makes the delay mono. Time and Feedback are set for both sides at once; it doesn't
matter which knobs you turn, the corresponding knobs on the other side will mirror your
adjustments by themselves.
Pi-Po
: Short for “Ping Pong”. Hard-pans the delayed signals so they alternate between the
left and right output channels.
Damping
: Rolls off the high-frequency content of the delayed signal. This knob controls how
quickly the highs are removed.
MIDI Sync
: Locks the Delay to MIDI clock and also synchronizes it with other Sync-enabled
functions like the LFO and the Phaser Rate.
