REVERB PREDELAY
This parameter controls the pre-delay time of
the given room simulation.
In a real room, sound travels quite a distance
and is reflected at least once before it reaches
your ear. This means that a certain amount of
time elapses before you hear the earliest reflec-
tions of the room signal. The bigger the room,
the longer it takes for the reflected signal to
reach your ear. This effect is emulated in a room
simulation be means of a parameter called pre-
delay. Irrespective of the values set for the other
REVERB parameters, the amount of pre-delay
has a decisive impact on our perception of the
size of a room.
When you set a high pre-delay value - say some
hundred milliseconds - you’re actually creating
an “unnaturally” large room. The room simula-
tion will sound washed out or much like a dif-
fuse echo. Pre-delay has a formative effect on
room simulation, particularly since - like with
the pure DELAY algorithms - you can use it to
match the reverb effect to the rhythmic context.
And like the DELAY parameters, pre-delay is in-
finitely variable, it is suitable for generating
feedback, and it can be synced up to the global
clock generator.
REVERB PREDELAY controls the absolute pre-
delay time in milliseconds (ms). The peak value
depends on the room size (REVERB TYPE, see
above) that you have selected because the
room simulation and pre-delay share the same
memory. Pre-delay time is infinitely variable.
Changing the delay time bends the pitch of the
reverb signal. REVERB PREDELAY will not ap-
pear in the display when the pre-delay amount
is determined via REVERB CLOCK (see below).

REVERB FEEDBACK
Available exclusively for the Rev+Feedb1 and
Rev+Feedb2 algorithms, this parameter con-
trols the amount of pre-delay feedback. Here
the room signal is repeated at intervals that are
determined by the pre-delay time. Note that the
signal level fades gradually. REVERB COLOR
also has an influence on feedback. The intensity
of the filtering effect generated by the low-pass
or high-pass filter increases with every repeti-
tion. Feedback is subtle when the decay time of
the room (REVERB DECAY TIME) is long. The
effect will become more prominent when you
set a short decay time and a long pre-delay
time.
