The best way to learn a new piece of gear is to start using it in your studio. This
section is designed to teach you how to edit your own effects using normal day-to-
day examples. Remember that programs are subjective and these are just guidelines.
If the program sounds weird when you’re all done, change it - that’s what the soft
knobs are for!
You can use the following section to edit any Program or Mix in the Andromeda.
But to get started, use a basic bass or pad patch that doesn’t have many effects to
begin with.  Whatever its effect type is, we’re going to change it to a simple reverb.
This will be a typical large, warm hall program, with a lot of space to swim around.

1.   If it’s not on already, press the 
EFFECTS ON/OFF
 switch to turn the LED on.
2. Enter Digital Effects Edit mode by pressing the 
DIGITAL EFFECTS CONFIG
 
button on
the top panel. The 
CONFIG
 page will be displayed.
3. Turn soft knob 
8
 (the 
TYPE
 parameter) fully counter-clockwise to select 
LG HALL
(Large Hall).
4.   Increase the 
SEND
 level to about 
80
 using soft knob 
1
, and the 
OUT
 level to 
80
using soft knob 
7
.
At this point, you will probably be able to hear reverb when you play the keyboard.
5. Press soft button 
2
 (
PARAM1
).
You’ll now see six different parameters in the display.

The quickest way to change the sound of any reverb program is to change the Decay
and LPF (Low Pass Filter) parameters. The Decay time (soft knob 
1
 on this page)
dictates the size of the room, and the LPF (soft knob 
4
) emulates the wall surfaces. To
simulate a large castle chamber with a few tapestries and other soft surfaces, we’ll set
the decay fairly long and the LPF relatively low. Don’t worry if the decay time seems
long, we can do other things to trim it down later.
6. Set the 
DECAY
 to around 4.638 (seconds) using soft knob 
1
.
7. Set the 
LPF
 to 5.650 (kHz) using soft knob 
4
.
Our next step is editing the Density (
DENS
) and Diffusion (
DIFF
) parameters.  These
are less obvious to hear, but can make a big difference on your sound. Density (soft
knob 
5
) affects how smooth the attack will be, and can approximate different surface
textures. A very high density would be good for simulating a polished marble room,
for example, and lower densities would simulate a rougher surface with more
discrete echoes. A Program with a very fast Attack and Decay can be a big help when
programming Density and Diffusion; it’s much easier to hear than on a sustained
sound—but don’t change Programs now or you’ll lose your changes so far!  Play the
keyboard while moving the Density up and down with soft knob 
5
 to hear its effect
on the hall.
8. Set the Density (
DENS
) to 74% for this room - not too rough, but not too glassy
either.
