Delay
The RP55 has 3 different delay types, Digital (D), Analog (A), and Ping Pong (P), each with up
to 2 seconds of delay time available. There are two different parameters used to program
the delay, Delay Variation and Time. The first parameter of the delay effect is Delay Type/
Variation, which selects the delay type to be used and varies the amount of feedback
(number of repeats) and level. The second delay parameter is Delay Time. This is indicated
by a value 1-99 (10ms-990ms), 1.0 and 2.0 (1 and 2 seconds respectively) in the display
when the Delay LED is lit. Delay settings are as follows:
d, a, p1=5% fback, level 15
d, a, p2=25% fback, level 15
d, a, p3=50% fback, level 15
Reverb
Using reverb in recorded program material gives the listener a sense that the material is
being performed in an actual room or hall. It is this similarity to actual acoustic spaces that
makes reverberation a useful tool in recorded music. Use the Value buttons to select one
of the nine predetermined settings. The higher numbers indicate there is more reverb level.
The reverb settings are as follows:
r1-r9 = Room
H1-H9 - Hall
P1-p9 - Plate
d, a, p4=5% fback, level 30
d, a, p5=25% fback, level 30
d, a, p6=50% fback, level 30
C1-C9=Church
A1-a9 = Arena
S1-s9 - Spring
d, a, p7=5% fback, level 50
d, a, p8=25% fback, level 50
d, a, p9=50% fback, level 50
