Simple “Parameter Adjusters”
There are a number of simple “parameter adjuster” modules:
• A knob module for simple numeric values.
• An rfader module for “rotary” graphical display instead of numeric values.
• An hfader module for “horizontal” graphical display instead of numeric values.
• A vfader module for “vertical” graphical display instead of numeric values.
• A textknob module for “text-valued” parameters.
• A tapknob module for “tapered” (or non-linear) values.
• A percentknob module for percentage display that corresponds to fractional control output.
They have several things in common:
• All have a single control output and no other signal inputs or outputs.
• All have a userobject output that can be connected to a menupage, gang, or head module.
• All have a menu statement and an 8 char name.
These modules are used by connecting their userobject outputs
to a menupage module (using the
<modify>
SOFT KEY on the
menupage module as shown to the right)
or the head module (using the
<modify>
SOFT KEY on the head module). The PARAMETER area
menu pages will then show the text or graphic menu
statement
s for the connected “parameter adjuster” modules.
The following pages describe the simple “parameter adjusters." To play along at home, load the
program Interface Modules from the “Programming” bank.
Hfader Module
The hfader module creates a horizontal graphic on a
PARAMETER area menu page. In the example screen to the
right it is the highlighted, upper left parameter. The area taken
up by the graphic is one half of the width of the screen and one
text line long. Eight of these can fit on a single menu page.
Six characters of the 8 char name are presented on the display
to the left of the graphic. The menu statement is not used.
Refer to the Modules Section for complete information.
Knob module
The knob module is the most popular interface module (in
factory programs). It generates a 20-character text string,
including a very versatile numerical display from the menu
statement
. Eight of these can fit on a single menu page.
