C4 Commander
<Param>
This tag defines a single parameter el-
ement which specifies all data needed to control
that function. If a mask attribute is present, the
specified mask will be applied to the parameter
message before it is sent to the instrument. If
a valuetext attribute is present, the appropri-
ate substitution will be made to the parameter
value displayed in the C4 commander.
<ParamMask>
This calls out which mask is to
be used for this parameter. It is possible (but
not very efficient) to have a different parameter
mask for each parameter (see <Param> above).
<ParamID>
The ID associated to the given func-
tion. It can be text or numerical. Normally this
should reflect the device manufacturer’s sysex
message parameter ID, so that if one is looking
up “parameter 34 – LFO” from the manufac-
turer’s spec, a simple search for PARAMID 34
would result in the display of this function for
editing.
<FunctionName>
Name of the given function,
e.g., Master volume. The FunctionName is
displayed as the default name in the C4 Com-
mander screen. Since the physical C4 is limited
to displaying only 7-8 characters, the C4 will au-
tomatically truncate this name to fit its display.
It is usually best to keep this parameter as de-
scriptive as possible and use the Layout rename
function to create good-looking onscreen text.
<Message>
The HEX message that will be sent
to the C4 when a V-Pot action is triggered.
<ValueRangeMin>
Minimum value for given
parameter.
<ValueRangeMax>
Maximum value for given
parameter.
Parameters
<ParamTable>
This tag defines the beginning
(and end) of the parameter table. All instru-
ment parameters must be contained withint
the begininning and ending ParamTable tags.
ParamTable contains a list of all parameters
(functions) that the C4 can control. The order
of the parameters determines the correspond-
ing default instrument layout order, so the first
parameter value is placed on the first C4 V-Pot
slot when dragging te entire instrument defini-
tion file onto the C4 Commander’s screen.
