Macro Commands In MIDI Scripts

This family of MIDI commands allows access to selected main Daqarta macro commands that may be useful in MIDI Changes scripts.

Each command starts with 'G' followed by a 2-letter code to specify the corresponding macro command. In addition, the first two commands in the table (corresponding to TiltdB and Tilt macros) use a period and a 2-letter suffix to specify the channel: .LI, .RI, .LO, .RO for Left In, Right In, Left Out, Right Out. (These same 2-letter channel selectors are given as prefixes in the macro versions.)

Please note that all of these MIDI commands require numerical values, even though the macro equivalents for some "radio button" controls may allow optional text versions. For example, SpectWind=Bkmn to set a Blackman spectrum window must here use the numerical equivalent GST=2.

The table below shows commands to set values, but MIDI scripts can also read these values or use them in MIDI IF statements. For example, to display the Left Out Tilt dB value as a decimal, you could use oLf=GCT.LI.

For additional information, click on the macro links for each command.
