Delay Effects
The Delay effects include delay, echo, looping and ducking effects. Delays are high
quality digital delays. Echoes are similar to delays, but low-pass filters have been added
to simulate the high-frequency rolloff that occurs naturally in acoustic echoes and in
echoes created with analog tape.
All MPX 1 Delay effects allow you to choose how delay times will be displayed. Select any
Time parameter and press Options. The following choices are available for each Time
parameter:
ms: time is displayed as milliseconds (delay time is fixed)
feet: time is displayed as feet – the equivalent distance from a sound
source requried to produce the delay (delay time is fixed)
meters: time is displayed as meters – the equivalent distance from a sound
source required to produce the delay (delay time is fixed)
echoes/beat: time is displayed as a rhythmic ratio of echoes per beat (delay time
varies with Tempo and can be changed at any time by pressing TAP
twice.)
TAP ms: time is displayed as milliseconds (new delay value can be “tapped in”
when this Time value is displayed for editing).
Another feature shared by all MPX 1 Delay effects is Fbk Insert. This option of the
feedback parameter allows you to route the outputs of another effect block to the delay’s
feedback input. If the other block is after the delay block, Fbk Insert will place it inside the
delay/echo feedback loop. This powerful feature is the key to obtaining many classic
effects.
