Sysex dump with parameters dumping to two bytes "ms" "ls"

[memorysplice]

I managed to get a working script using this thread.

Where I am at now, I there are parts of the sysex that require two separate bytes to update one parameter.

Here is a example of the message.

F0 41 10 00 00 00 7B 12 19 42 20 00 00 00 00 01 = first part of sysex

01 03 = "01" ms and "03" ls "These two bytes correspond to a 255 byte parameter."

00 0A = "00" ms and "0A" ls "These two bytes correspond to a 2nd 255 byte parameter."

and so on and so on

00 05 00 0B 00  00 02 04 03 02 00 00 00
20  00 00 00 00 00 15 F7                        

Here is the code that I am using. “Thanks to dasfaker

	elseif  ( midiMessage:getData():getByte(09) == 0x42) then

			modulator18= midiMessage:getData():getByte(11)

		panel:getModulatorByName("Patch_EFX_1"):setModulatorValue(modulator18, false, false, false)

My question is what kind of lua script do I need that will reference two separate bytes that will update a single parameter that has a range from 0-255?

After doing some digging around, I found this to possibly work with. Does anyone have any thoughts?

You commented out the name of your script and the “end”.. Those two elements should be like the bun of your sandwich, so to speak, and they shouldn’t be commented out with double dashes. One goes at the top, one goes at the bottom. This concept is important to grasp. When you start a function you must end a function.

it should be something like:

[code:1jfd3aiv]Patch Configure = function(modulator, newValue)

FilterMsb = midiMessage:getLuaData():getByte(54)
FilterLsb = midiMessage:getLuaData():getByte(55)

FilterValue = (FilterMsb*16)+(FilterLsb)

panel:getModulatorByName(“VCF Cutoff”):setModulatorValue(FilterValue, false, false, false)

end[/code:1jfd3aiv]

modvalue = 128 * programData:getByte(x) + programData:getByte(x+1)

Thank you. Will try now and get back.
