If you crank the pitch wheel all the way up, you’ll get the screen
to the right. The bar graph reads
100.00
, full maximum.
The next parameter we come to is
scale
. After all this discussion we may have forgotten that what we’re
actually doing is
modulating a parameter
, but that
is
what we’re doing. And parameters come in all shapes and
sizes (like people). For example, we must be able to modulate a delay time from 5 milliseconds to 25 milli-
seconds with a full rock of the foot pedal just as we must be able to modulate a pitch shift from 0 cents to -
4800 cents with a full rock of the foot pedal. The
scale
parameter allows us to do just that (
we had you change
scale
when modulating
Digital 1
so that the external controller could actually modulate it
!).
With
scale
set to
100%
, the external controller’s range corresponds to the full range of the parameter’s val-
ues
(different types of parameters will have different “full ranges”)
. With various settings of
scale
, the parameter being modu-
lated, and the external controller doing the modulation, it is possible to “pin” the parameter being modu-
lated at its minimum or maximum values. Adjust
scale
or the value of the parameter being modulated to
remedy this situation
(see the examples below)
. Note: It is also possible to set
scale
to a negative value. Doing so
allows the value of the parameter being modulated to
decrease
while the external controller is
increasing
.
The final parameter on the external modulation menu page is just a duplicate of the parameter we’re modu-
lating. Its value reflects the applied external modulation, so you can see the result of all your futzing as you
futz
(the external modulation’s value will be ADDED to the parameter’s value)
. Additionally, you can adjust the value of the pa-
rameter while you futz (we’ll see why you’d want to in the examples that follow).
If you modulate a gang of four or more
parameters, they will
not
be shown on the external modulation menu page because there isn’t enough room to fit them all!
There are two ways that you can obtain your desired range of modulation. The first involves educated
guesses and the second involves math. First, we’ll give an example using the “educated guess” method.
We’re
going to ditch the
Digital 1
parameter we’ve been modulating thus far. To avoid future headaches, change the
mode
to
off
and then press the
[*done*]
SOFT KEY
.
Load a simple delay program from the “
Delays
” bank if you
would like to follow along. We’re going to modulate the delay
time in this simple program. Highlight a “
delay
” parameter in
the
PARAMETER
area.
Press and hold the
SELECT
key until the menu page shown to the
right appears
(again, we’re “remote controlling” this parameter).
Let’s say we want to modulate it with the external controller
“mod wheel on MIDI channel 3.” We could either directly adjust
the
mode
and
channel
parameters, or we could use the
Capture
Midi
feature to select it.
Let’s also say that we want the
delay
to vary from
100.0 ms
to
300.0 ms
. With the mod wheel at
0
as shown above, we change
delay
to
100 ms
.
