15-16 Ambience: The reverb of any room consists of so-called early reflections and the reverb tail. This
algorithm emulates the first 15 of these early reflections. Since our ears use these reflections to
determine the room size, they can be employed to create subtle and impressive reverb densities,
without clouding the overall signal with long reverb tails. The PARAMETER control modifies the room
size, while EFFECT A adjusts the pre-delay time, and EFFECT B governs the mix between original and
effect signals.

17-26 Wah/Delay/Distortion: In general, filters are used to provide some static equalization of a signals
frequency response. The wah effect  combined with delay and distortion in this preset  allows the
mid-range frequencies to pass, while it more or less suppresses the remaining frequency ranges.
Guitarists such as Jimi Hendrix and Eric Clapton made this effect popular, and it still hasnt gone out of
fashion. Use the PARAMETER control to adjust the delay time. EFFECT A allows you to determine the
distortion intensity, which also depends on the volume settings chosen in the HEAVEN and HELL
channels. With EFFECT B you can edit the delay mix. Using MIDI controller #15 you can edit the
operating range of the wah effect, e.g. via a MIDI foot controller. In this way, it is possible to use the
wah effect like an analog wah foot pedal.

20 Delay/Reverb: After a normal delay with adjustable delay time, the signal passes a reverb with different
reverb times that are preset by various variations.

21-29 Delay: This algorithm delays the input signal and generates several repeats. The first four presets
(21 through 24) produce a stereo delay, with the PARAMETER control setting the delay time for the
right channel. The left channels delay time is 2/3 as long as that on the right side. As usual, EFFECT A
and EFFECT B determine the mix between original and effect signals. Delay presets 25 through 29
offer long mono delays, which can be adjusted in their delay time (PARAMETER control), delay
feedback (repeats, EFFECT A control) and delay mix parameters (EFFECT B control).
