increases. As you move the controller up from the bottom of its travel, the output will increase
faster than normal until you reach its midpoint, at which point it will start to increase slower
than it would normally. Cos+ sets the curve to resemble a cosine wave, in which the ÒbulgeÓ
goes the other way: the response is less than normal as you approach the controllerÕs midpoint,
and then increases faster than normal as you move higher.
Entry and Exit Values
Entry value allows you to specify an initial value for a controller in a Setup that will be sent
whenever you select that Setup. For example, if you want to make sure that a voice in a Zone is
panned to the center whenever you select the Setup, you would assign MIDI Controller 10 to
one of the physical controllers, and then set an Entry Value of 64. Or perhaps you want to make
sure that all of the modulation in a Zone is turned off when you select a Setup. Assign MIDI
Controller 1 to a physical controller and set its Entry Value to 0.
Entry values ignore the current position of the physical controller when the Setup is selected. In
fact, if the physical controller is above or below the Entry Value when the Setup is selected
(which it often is), moving the controller will have no effect until it is past its entry value. In the
modulation example, moving the assigned controller wonÕt turn on any modulation until itÕs
pushed all the way down, and then up again.
An Entry Value of None is quite different from a value of Ò0Ó. ÒNoneÓ means that there will be
no initial controller command when the Setup is selected, and any subsequent movement of the
physical controller will be effective. (The position of the physical controller when the Setup is
Þrst selected, however, is still ignored.)
Exit Value tells the PC88 to send a value for that controller whenever you leave the Setup,
either by selecting another Setup or by switching to Internal Voices mode. It can be very useful
when a controller is doing something special to the sound which you donÕt want to continue
after you leave the Setup. For example, if you want to make sure a ZoneÕs pan position is
centered whenever you leave a Setup, you would give an Exit Value of 64 to any controller
assigned MIDI Controller 10. Or, if you wanted to make sure a channel was playing at full
volume when you left a Setup, you would give an Exit Value of 127 to a controller assigned
MIDI Controller 7. Again, ÒNoneÓ means no command is sent.
The Switch Controllers
Switch (physical) controllers have only two states: on and off. They are found after the
Continuous controllers when you are scrolling the menu. They are:
• Buttons E, F, and G
• Switch Pedals (ÒSwitchPdlÓ) 1 and 2
The parameters for Switch controllers are slightly different from those for continuous
controllers. The Þrst parameter is Switch Type (SwType). The choices available are Momentary
in which a switchÕs action lasts only as long as you are pushing it, and Toggle, in which the
switchÕs action lasts until you press it again. The Momentary mode is used for functions like
sustain or portamento, while the Toggle mode is used for functions such as arpeggiator start
and stop or latch, program GotoÕs, and transpositions. The buttons show which mode they are
in by the behavior of their lights: if a button is in Momentary mode, its light glows only as long
as you are holding it, while if it is in Toggle mode, the light stays on until you press it again.
Bear in mind that button assignments are independent per zone, and since thereÕs just a single
light per button, the light only shows the state of the button for the current zone. When you
press the button, however, it executes its assignments for all four zones.
The next parameter for the Switch controllers is On Controller (On Ctrl). This determines what
MIDI Controller or other message will be sent when the switch is ÒonÓ Ñ either pressed or
