This message is not sent by this Instrument.
Receive
Receipt change the value of Parameter7 [0-7] (7-Bit Parameter) explained under “21.3 DSP Parameters”. Any message
received that corresponds to the parameter of a number not being used by the currently selected DSP is ignored.
Note 1:
Received values and parameter setting values
The range of the value of each DSP Parameter 7 array element depends on the selected DSP or array number.
Unlike manipulation of a DSP parameter using a System Exclusive Message, a value received by this control change message
is always in the range of 0 to 127, but the range is changed in accordance with the setting range of the applicable parameter
setting. Because of this, it is impossible for a value to be outside of the range.
Conversion to the parameter setting value from the value received with the message can be represented in general terms
by the expression shown below.
For details about Parameter 7 of each DSP, see the explanations under “VI DSP Parameter List”.
