toggled the Þrst time. The list of available controllers is the same as for the continuous
controllers, and can be accessed the same way.
Then comes On Value: the value of the Controller when the switch is on. In the case of
conventionally-switched functions, such as sustain, the On Value will be 127. (For example, the
default for Switch Pedal 1 is Controller #64 Ñ Sustain Ñ with an On Value of 127.) However,
you might want to use a button or pedal as a ÒsoftÓ switch, in which case you might set On Ctrl
to 7 (Volume) and On Value to 50. On Value can also be set to ÒNoneÓ, so that turning on the
switch has no effect at all in this Zone, which can be useful when you are using one switch for
multiple functions in different Zones.
Off Ctrl is the MIDI Controller or other message that is sent when the switch is turned off Ñ
either released or toggled a second time. Whenever you set the On Controller, it automatically
sets this parameter as well to match. If you want the Off Controller to be something else,
however, you can change it after setting the On Controller. A situation where this might come
in handy is when you want to switch a synth between Mono and Poly mode. The On Ctrl
would be 126 (MonoOn) and the Off Ctrl would be 127 (PolyOn).
Off Value is the value of the Controller when the switch is off. The default value is 0. You might
want to change this, as in the Òsoft switchÓ example above: in order to bring the Zone up to full
volume when you release the pedal, set Off Value to 127. ÒNoneÓ is also a choice here.
Entry State determines whether an initial setting for the switch will be sent when the Setup is
selected. There are three choices: None (no message), Off (the Off controller and value), and On
(the On controller and value). In a button, if the entry state is ÒOnÓ, the light will glow as soon
as you select the Setup.
Exit State similarly determines whether a setting for the switch will be sent when the Setup is
left, either for another Setup or for the Internal Voices mode. The same three choices are
available. Very useful for turning off Sustains when changing Setups.
Do These Parameters Always Mean Something?
Be careful not to set up parameters that will do crazy things. When in doubt, leave things off, or
at the factory default settings. All of the Special Function controllers should have their Entry
and Exit values set to ÒNoneÓ.
On some of the higher-numbered MIDI controllers and Special Function controllers, the on
and/or off values donÕt have any meaning, because the controllers have very limited
functionality. The following list shows these. Ò>0Ó means you can use any value thatÕs greater
than zero. Ò=0Ó means the value should be 0. ÒxÓ means you can use any value, except ÒNoneÓ.
ÒÖÓ means the value does count for something:
On Value Off Value
120 All Sound Off >0 x
121 Reset All Controllers >0 x
122 Local Control Off >0 =0
123 All Notes Off >0 x
124 Omni mode Off >0 x
125 Omni mode On >0 x
126 Mono mode On Ö x
(the On value, in some synths, speciÞes the number of MIDI channels to respond to, with one voice on each)
127 Poly mode On >0 x
