Sysex Dumps via LUA scripts…need help

[wildthing]

Hi guys, I decided to start a new project and i would like to build a controller panel for my jomox.
I’ve already built modulators and i would like to add 2 more buttons. The first to get edit buffer values from the synth to the panel modulators and the second to send actual panel values from CTRLR to jomox.
I would like to do it using SYSEX messages but i never manage that stuff before. I’ve understood the message structure but i need a little help to start.
Can someone be so kind to make an example on how can i settle LUA scripts to get those goals?
Any help would be much appreciated! Thanks in advance….

P.S. I’ve attached midi implementation table

Hi , you need to create LUA function and selest it in the main panel recive message method.
Example routine could be like this:

--
-- Called when a panel receives a midi message (does not need to match any modulator mask)
-- @midi   CtrlrMidiMessage object
--

Recivelist = function(midiMessage)

if panel:getRestoreState() == true or panel:getProgramState() == true then
		return
	end

	local messageType = midiMessage:getType()
	

	if (messageType == 5 and midiMessage:getSize()~=2) then

		local s = midiMessage:getSize() -- Size of the midi dump received
		console ("memory block is "..midiMessage:getSize().." bytes, data:")

		local recKPAID = midiMessage:getLuaData():getRange(1,3)
    	        local recFunctionCode = midiMessage:getLuaData():getByte(6)
		local Instance = midiMessage:getLuaData():getByte(7)
		local recNrpnMSB = midiMessage:getLuaData():getByte(8)
		local recNrpnLSB = midiMessage:getLuaData():getByte(9)

		if (recFunctionCode == 0x7e and Instance == 0x00) then
		
			if (recNrpnMSB == 04 and recNrpnLSB ==03) then

				local partialmessage=midiMessage:getData():getRange(10,s-12)

			
				
		
				elseif (recNrpnMSB == 06 and recNrpnLSB ==03) then

				else
			end
		
	    end
	end
end

I tried this on a d110. i request a dump, and an answer comes (as seen in the monitor), but i think my function never gets called. i put a console call in there, and i cant see anything. also, is there an api reference anywhere?

You have to select this method(function) in the right men in Panel Edit Mode “luaPanelMidiRecived” “Called when a panel recives midi message”.

Hi Daniel and Wildthing,

Maybe look through this source code for clues on how to do it – you’ll need a checksum function (for the Roland D-110) – there’s one in there you can use.
