ext1 through ext16
Modules external to the Eclipse (such as MIDI controllers or foot pedals) modulate the pa-
rameter. You decide which external modules are associated with ext1, ext2, ext3, and so
on at SETUP page 3 EXTERNAL.  see page 45 for more on External Controllers
hotkey_1 thru hotkey_16
The hot keys found under HOT KEYS can be used as a modulation source. If a hot key is
present it will already be controlling a parameter; using it as a mod source allows it to con-
trol others at the same time. Suitable choices of scale values make this a very useful facil-
ity.
see page 33 to learn about Hot Keys

param1 through param4
One of four “generic” parameters modules located at PARAMETER page 2 <EDIT MOD>
page 2 PARAMS modulates the program parameter of interest. If you patch a bunch of pro-
gram parameters to one of the generic parameters, you can alter all of the patched parame-
ters in concert simply by adjusting the generic parameter. Pretty handy.  see page 43
Use (MONITOR) to view the current value of the module selected under
(SOURCE). To the right, we see a value of about 60%. If the module is
something very dynamic like lfo#1 or follower#1, this (MONITOR) will
jump around quite a bit.
Parameters with active modulations applied will have their names un-
derlined on the softkey labels.
Scaling Modules and Selecting Modulation TYPE
Here’s the situation: let’s say you’ve selected lfo#1 to modulate a low
pass filter cutoff frequency (FREQ). When the LFO is at the bottom of
its cycle, will the filter be at 0Hz? You wouldn’t hear anything. When the
LFO is at the top of its cycle, will the filter be at 20,000Hz? This might be
what you want, but maybe you only want the filter to cycle between
2000Hz and 3000Hz. How can we make that happen?
Here’s the solution: Scaling
. Before holding down the (FREQ) soft key,
enter a value of 2000Hz. We’ll call this value the “base” value below.
Now, hold down the soft key and press <MODULATE> as discussed
above, and press HOTKEY to nagivate to page two where the Scale pa-
rameter is located. The total range of possible modulation (
parame-
ter_range
) for a frequency parameter is 0 ~ 20,000, but we only want a
modulation of 3,000 – 2,000 = 1,000. To scale, enter the value of 1000
in the (SCALE) setting.
Great! Now we need to select the (TYPE) of modulation. We have four choices:
unipolar unipolar uses the base value (the value of the parameter before modulation) as a starting
point and adds the modulation value to it.
In the example above, the parameter value will vary between 2,000 and 3,000 (it starts at
the base value and modulates up).
