About the Parameters
Each of the 16 presets in Alex consists
of a unique combination of as many as 32
different parameters. These fixed parame-
ters determine the type of preset — hall,
room, plate, etc. that you will hear when you
turn the REGISTER/PRESET knob.
For each preset, several parameters
have been made available for front panel
control through the DECAY, DELAY and FX
LVL controls.
In Halls and Rooms (1-6), and in the
Plate presets (9-12), DECAY sets the nomi-
nal reverberation decay time for a predeter-
mined room size which is unique to each
preset.
In the Inverse and Gate presets (7-8 ),
DECAY changes both the size and the char-
acter of the program, while DELAY varies the
predelay before the gated effect. (Note that
changing the setting of DECAY in either of
these presets will briefly mute the effect.)
In Chorus (13), Echo (15) and Delays
(16), DECAY controls recirculation. In the
Flange preset (14), DECAY controls flange
resonance.
DELAY generally sets the amount of
predelay (the length of time between the
input of signal and the onset of reverbera-
tion). The range of this control varies with the
type of preset.
In Chorus and Echo, DELAY controls
the echo delay. In Flange, it controls the
depth of the flange effect. In Delays, it con-
trols the delay time for the first of four equally
spaced delay taps.
In each preset, FX LVL sets the level of
the effects being added to the signal.
Note that the setting of the MIX control is
very important with several of the presets. In
the Inverse and Gate presets, MIX allows
you to set up anything from a subtle thicken-
ing or enhancement, to a solid wall of reverb.
In the Chorus and Flange presets, MIX should
be set higher than 50% wet to get rich chorus
and flange effects.
