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 of original and effect signals. This effect is
particularly impressive when played through a pair of headphones.

17-19 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 CLEAN and OVERDRIVE 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: This effect produces a normal delay with adjustable delay time that passes a reverb
whose mix ratio can be edited.

21-29 Delay: This algorithm delays the input signal and generates several repeats. The first five 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 of original and effect signals. Delay presets 25 through 29 offer long mono
delay, which can be adjusted in their delay time (PARAMETER control), delay feedback (repeats,
EFFECT A) and delay mix parameters (EFFECT B).
