Tip: To match your delay time to your tempo, use your song's tempo in "B.P.M."
(Beats Per Minute) in the following equations:
Dotted Quarter note
Quarter note
Quarter note triplet
Dotted 8th note
Eighth note
8th note triplet
Dotted 16th note
Sixteenth note
16th note triplet
For example: A quarter note delay time @ 120 bpm would be figured as
or 500 milliseconds (msec).
Tip: Sometimes it's useful to have a delay with a low Feedback value land ahead or
behind the beat a little, especially if you're matching the audio in a sampled
loop. If you want your delay to push the beat, shorten the delay time in small
increments until you find the right "pocket". If you want it to drag, lengthen the
delay in small increments until it sounds right.
P5 The Delay FEEDBACK Parameter
This Parameter determines how long the Delay will repeat. Higher Values give you a
higher repeat count (more feedback) and lower Values give you lower repeat count
(less feedback). A Feedback Value of 00 will cause the Delay to repeat only once and
then stop.
To set the amount of Delay Feedback, move the cursor beneath the Value and then
turn the Value encoder to adjust the Feedback amount:
DELAY FX
Feedback: 4 0
P6 The Delay OUTPUT TO REVERB Parameter
This Parameter is not as complicated nor obscure as it sounds. Simply stated, this
Parameter allows you to send the output of the Delay Effect to the Reverb Effect. By
adding Reverb to the Delay Effect, it can move the delay further back in space and
give you increased dimension.
To set the amount of Delay Effect that is sent to the Reverb Effect, move the cursor
beneath the Value and then turn the Value encoder to adjust the Delay Output's send
amount:
