A digital delay emulates an analog tape-echo unit. A tape-echo is a special type of tape recording. 
It uses one head to record a signal and up to four heads to replay it. The delay time is set by the 
tape  speed  and  the  space  between  the  heads.  A  digital  delay  essentially  performs  exactly  the 
same function as a tape-echo, but offers more renements and adjustments than its mechanical 
counterpart. A delay essentially creates an echo, although you can often use delays to create more 
complex time-based effects. The source signal is delayed so that it is heard later than it actually 
occurred.
   Delay time. Delay time is the time 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 distinct echoes can be used to create thickening effects. Whether these echoes are timed 
with the tempo is a matter of stylistic choice.
   Variable  feedback.  The  variable  feedback,  or 
regeneration
,  produces  multiple  decaying  re-
peats. Increasing the feedback value increases the number of echoes as well as the resonance 
that is created as one echo disappears into another.
   Note: Using the Tap button on the StudioLive, you can speed up or slow down these repeats or, 
more commonly, time the repeats to occur with the tempo of the music.
