Delay / Reverb (Menu)Filter Envelope
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 CLOCK
When you set it to OFF, the absolute predelay
time is determined in milliseconds. If you select
a note value, then the predelay time is set to the
value of this note. The absolute length of this
note value depends on the value entered to
CLOCK TEMPO in the global clock generator
(refer to this section). In this case, the absolute
predelay time in milliseconds is ignored.

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.
