LAU midiMassageReceived cause crash

[DMM]

Trying to get a modulator to update on patchdump.
As soon as i enable the lua code in the panel ctrlr crashes.[code:33cey2ja]–
— Called when a panel receives a midi message (does not need to match any modulator mask)
—

midiMessageReceived = function(midiMessage)
s = midiMessage:getSize()
if s == 67 then
out = panel:getModulatorByName("outputLabel")
out:getComponent():setPropertyString ("uiLabelText", midiMessage:toString())
console("received program data")

assignValues(midiMessage)
end
end

function assignValues(midiMessage)
console ("assignValues")
lastSavedProgram = midiMessage:getLuaData()
programData = midiMessage:getLuaData():getByte(
— unpackedData = utils.unpackDsiData(programData)

console ("RAW DATA: ")
console (programData:toHexString(1))
— console ("UNPACKED DATA: ")
— console (unpackedData:toHexString(1))

panel:getModulatorByName("modulator-1"):setModulatorValue(programData:getByte(, false, true, true)

end
[/code:33cey2ja]

Can anyone tel me why?
It’s a simple panel with just one modulator

[atom]

can you also paste the output from the console here ? have you tried removing more lines to see witch one causes the crash ?

[DMM]

Yes i’ve taken out some lines.
It’s a test panel with one modulator only (trying to get the code working for the JX-8P)
Ctrlr crashes with all midi input

The sysex when i press the preset button on the JX-8P:
[list:2l8igms2]

[/list:u:2l8igms2]

[atom]

that won’t work

[code:1rev88nr]
programData = midiMessage:getLuaData():getByte(
panel:getModulatorByName("modulator-1"):setModulatorValue(programData:getByte(, false, true, true)
[/code:1rev88nr]

programData is a byte (a number) you can’t call method on it.

[DMM]

Getrange does the same. Also gives a crash

[DMM]

Even with this little lua code ctrlr crashes[code:33riel45]–
— Panel executes when when a midi message is received
—
—

midiMessageReceived = function(midiMessage)

s = midiMessage:getSize()
— console(string.format ("I got the size of the message, here it is : %d",s))
end
[/code:33riel45]
I think console should show me the sysex byte lengt

[atom]

Can you tell me what revision of Ctrlr are u using. I’ll check and see if there is something wrong, but even if there is it will take some time to fix cause i dismantled Ctrlr and need to put it back together in a better way and that might take a while.

[DMM]

I’ve the latest build and tryed the stable one.
Both with the same behavior.

[DMM]

Windows version 32bit

[atom]

Can you try this piece of code as part of your method, and see what the console will tell you
[code:2r828jir]
data = midiMessage:getLuaData()
console (string.format ("midiIncomming size: %d", data:getSize()))
console ("HEX: "..data:toHexString(1))
for i=0,data:getSize()-1 do
console (string.format("BYTE[%d]: %d/%x", i, data:getByte(i), data:getByte(i)))
end
[/code:2r828jir]

[DMM]

if i input this in the console i’m getting an error.
ERROR: [string "data = midiMessage:getLuaData()…"]:1: attempt to index global ‘midiMessage’ (a nil value)

[atom]

No no, edit the method, and replace it with:
[code:asyo8m0r]
midiMessageReceived = function(midiMessage)
data = midiMessage:getLuaData()
console (string.format ("midiIncomming size: %d", data:getSize()))
console ("HEX: "..data:toHexString(1))
for i=0,data:getSize()-1 do
console (string.format("BYTE[%d]: %d/%x", i, data:getByte(i), data:getByte(i)))
end
end
[/code:asyo8m0r]

then try to generate some midi data to the panel and watch the LUA console for any events.

[DMM]

Haha you must be thinking ” title=”Wink” />

But there is no output in the console an ctrlr crashes.

[DMM]

What i’m finding strange is when i fire a random sysex string at other pannels
like the Virus or Blofeld, ctrlr doesn’t crash.

[atom]

That’s why i’m trying to figure out what is happening, have you tried my piece of code ?

[DMM]

Yes and also ctrlr crashes.

[atom]

Allright can you send the panel to me or attach it here so i can debug it ?

[DMM]

In the vst version ctrlr doesn’t crash but there is no byte length shown in the console

[DMM]

Here is the paneltext

[atom]

It’s weird, i think there is something weird happening with the naming scheme here. Try to create a new panel, add a method call it myMethod and paste the code from the old method, so that it look like this:
[code:6dx2hvce]

—
— Called when a panel receives a midi message (does not need to match any modulator mask)
—

myMethod = function(midiMessage)

data = midiMessage:getLuaData()

console (string.format ("midiIncomming size: %d", data:getSize()))
console ("HEX: "..data:toHexString(1))

for i=0,data:getSize()-1 do
console (string.format("BYTE[%d]: %d/%x", i, data:getByte(i), data:getByte(i)))
end

end
[/code:6dx2hvce]

but try it on a new panel and see if that keeps crashing.
