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.

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.

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).
