HOW A PROGRAM INTERFACES WITH THE PARAMETER AREA
Simple Interface
Because you really shouldn’t be reading this manual if you haven’t
already read the User Guide, we’ll assume you’ve seen menu
pages in the
PARAMETER area.
A menu page, with an associated
SOFT KEY, is created by connecting a module’s userobject output to a
userobject input on something called the “head” module. Every program has one (and only one) head
module. The actual parameters that will appear on a menu page created this way depend on the module
being connected. They will usually be the values of all unconnected control inputs..
For example, consider the simple delay module connected to a filter module we started this chapter
out with
(again, as shown in VSigfile). Now that you’ve learned a little more, we’ve “unhidden” the control inputs
for these modules
(the unconnected ones on the left) and the userobject outputs (the ones on the lower right). As you can see,
we’ve connected their userobject outputs to the userobject inputs on the head module
(the disembodied “1” and “2” in
the lower right corner. The observant user will spot that the head “module” doesn’t really look like the other modules)
.
If we run this program and go to the
PARAMETER area, we see
the screen to the right. A menu page exists for each module that
contains parameters pertinent to its functioning.
Note that the order of the connections to the head module’s userobject inputs dictates the order of the SOFT
KEYS
.
Constructing programs this way is fast and easy. Just concentrate on the audio connections and then
connect every modules’ userobject output to the head module. However, the user interface isn’t very “slick”
and may be cumbersome to use. That’s where “custom” interface construction comes in. . .
