stateData

[atom]

This feature is in all types that Ctrlr supports, if there is some different behavior you need to let me know what exactly is different and i’ll have a look.

[zeoka]

Ok
I open ctrlr in maschine 2.2
I load the panel
I’ve my uiLabel with “SDFG” text and a “global data” custom comp that is “attached” to another uiLabel to memorise,update and load global data.

I save it in maschine instrument format

Then I rename “SDFG2” , change “global volume” so that change the “global hex “uiLabel and save it in maschine format

Now I can load maschine instrument presets and that works fine
(name of program and global setting are loaded,panels are not reloaded multiple times )
EXCEPT for the midi ports (I’ve set them to none) so I don’t have error now
but that means set the midi ports each time presets are loaded

But The main problem is all the state data doesn’t work in instances

always the first state (when instance is done) is loaded
whatever maschine instruments (with differents prog names and global settings) I save….

I precise I’ve also a uiLabel that “returns” the 2 statedata var() to see what happens. Ctrlr 5.3.57

[zeoka]

Hello Atom

Just tried the 5.3.77
restricted instances is still have stateData() not working

I think (my 2 cents theory) some codes are not here(the save option is not there on
the window bar menu so i think codes attached are not there) and nothing happen
the maschine file doesn’t take the data

With ctrlr.dll there is no problem

[atom]

I did a small fix for thix yesterday, check out the next nightly when it comes out, maybe it will fix the isse.

[zeoka]

yup !

[zeoka]

Hi
This is working fully now !

The maschine file is always 14 kb , the data is not uptated in my UIlabel that monitors the state data but this is working now. I can remove it now

Thank you

I’m facing a strange problem passing data from StateData to memory blocks.

In the console I put the following code:

Part1CommonSyx:loadFromHexString(myStateData:getProperty("Part1Common"))
console(Part1CommonSyx:toHexString(1))
Part2CommonSyx:loadFromHexString(myStateData:getProperty("Part2Common"))
console(Part2CommonSyx:toHexString(1))
Part3CommonSyx:loadFromHexString(myStateData:getProperty("Part3Common"))
console(Part2CommonSyx:toHexString(1))

and I get the correct result:
f0 41 10 6a 12 01 00 10 00 01 00 00 03 06 08 7f 40 38 f7
f0 41 10 6a 12 01 00 11 00 01 01 00 04 01 00 7f 40 76 f7
f0 41 10 6a 12 01 00 12 00 01 00 00 01 01 00 40 40 13 f7

But if I print again the two memoryBlocks, now the result is this:

console(Part1CommonSyx:toHexString(1))
console(Part2CommonSyx:toHexString(1))
console(Part3CommonSyx:toHexString(1))

f0 41 10 6a 12 01 00 12 00 01 00 00 01 01 00 40 40 13 f7
f0 41 10 6a 12 01 00 12 00 01 00 00 01 01 00 40 40 13 f7
f0 41 10 6a 12 01 00 12 00 01 00 00 01 01 00 40 40 13 f7

Part1CommonSyx and Part2CommonSyx are now equal to Part3CommonSyx. For some reason, the last string assigned to the last memoryBlock is assigned to the first and second memoryBlock.

Any idea of what’s going on?

[atom]

Well for start:
Part3CommonSyx:loadFromHexString(myStateData:getProperty(“Part3Common”))
console(Part2CommonSyx:toHexString(1))

you are writing to Part3CommonSyx and printing Part2CommonSyx.

Also i don’t see how the data can be altered on it’s own, unless your lua code modifies those parts of memory somehow and during the time you print them something changes this memory segments.

[dasfaker]

Finlay solved the issue (forgot to post it here). The above had a typo.

I was wrongly assuming that loadFromHexString was replacing the existing data in the MemoryBlocks, but in reality it was adding data at the end, leaving the existing data unaltered. I just needed to initialize the MB before loading the string to get the expected values.

Hi
I would create a node per property then I could call them by index and name the prop
string.format(“%x”,myvalue) ,that way I never need to call a name and I can do a loop

But not sure about property
I started something but it seems I’m wrong
I believe the node name and the property name is the same but not sure

I added after “SINGLE” identifier as ctrlr wants an extra value
The formula in not the same in juce
edit:
I’ve done :

myMethod = function(stateData)
stateData:addChild("SINGLE",0,nil)
stateData:addChild("MULTI",1,nil)

 for r = 0,47 
  do if r <= 3 
     or r >= 16
   then s = string.format("Buffer%x",r)
        stateData:getChild(0):addChild(s,r,nil)
        t =  stateData:getChild(0):getChild(r)
        t:setProperty(s,string.format("Hello%x",r),nil) 
    end
 end
 for r = 0,47 
  do s = string.format("Buffer%x",r)
     stateData:getChild(1):addChild(s,r,nil)
     t =  stateData:getChild(1):getChild(r)
     t:setProperty(s,string.format("Hello%x",r),nil) 
 end

end

but still the same error

Anyone oO ?

[atom]

The first argument in this error message is an indication of the type it’s executed on (something like “this” parameter, you don’t pass it in, it’s already there).

You should do something like

parent = ValueTree("parent")
parent:setProperty ("parent_property_name", "value", nil)
child = ValueTree("child")
child:setProperty ("childs_property_name", "value", nil)
parent:addChild (child, -1, nil)
xml = parent:createXml()
console (xml:createDocument("", false, false, "", 0))


-1 means just append the next node, i wouldn’t attempt to index those nodes without further reading and testing this, i don’t know what happens when you remove them and add new ones, there are some JUCE internals that i don’t know that could mangle those numbers for you.

make sure you know what you are doing.

Thank you
I get the structure , a node is not automatically a value tree , that was wrong to believe that Now I would add more nodes but I am getting wrong with getProperty

because the var() returned or inserted by setProperty() prefer so much to be a string ! impossible to get the property value if it is a memoryblock

in the picture k is nil if the value is in memoryblock form but a string only
MySingle[?] are valid memoryblocks
what I’m missing ?

Ok I get it

Hi,
maybe you can help me with this?
I’m trying to save state data with a example script(called when DAW save state):

KIPRString=""
SaveStateData = function(stateData)

stateData:setProperty("KIPRenc64", 1234, nil)
end

Script for loading data:

function LoadStateData(stateData)

KIPRString=stateData:getProperty("KIPRenc64")

end

And it is working.
But when I close and reopen the panel I have following error (and the method is disabled):
What: C
Namewhat: method
Name: setProperty
Error message: No matching overload found, candidates:
void setProperty(CtrlrLuaObject&,Identifier const&,var const&,bool)

Cannot try it right now, but try with KIPRString=stateData:getPropertyInt(“KIPRenc64”), as you are storing an integer value

[daimondamps]

Thanks dasfaker, but getPropertyInt not working.
Besides SaveStateData method is disabled when panel is loading.
I’ve tried to use string to store but with the same error.

SaveStateData = function(stateData)

stateData:setProperty("KIPRenc64", "StringToStore", nil)
end

I’ve tried what(stateData) in console and it gives me :

>>> what(stateData)
Object type [nil]

EDIT:
I’ve renamed (removed and created again) my SaveStateData(stateData) to savedata(stateData)
and now is working 🙂
Something must went wrong with name SaveStateData for the method.

Sometimes I just need to sleep with the problem to solve it:D

The panel tree is not flushed to disk with every save, it’s only updated in memory, if you want to flush it to disk you do save ctrlr state (this is the equivalent of saving your project when host ctrlr as a VST). This is done for performance reasons.

Hi Atom and dasfaker,
can we be more precise here?
Let’s imagine we have a user of a panel and the developer has foreseen a way to store some key values (last used sound and bank for example) in statedata.
What should the programmer do (what to write and where) to secure that this data is saved when the user close the panel or quit Ctrlr and what should the programmer do to secure that this is loaded into variables and that the variables containing the key values can be used at panel opening.
I think that with that precision, the statedata read/write will be better understood.
Thx to both!

[dasfaker]

Ctrlr: Closing the panel don’t save the stateData. You should do Ctrl+Alt+S (save Ctrlr state) or close Ctrlr with the panel opened to save stateData

Exported Instance Standalone: Closing the instance saves stateData

Exported Instance VST: Saving the DAW project save the stateData.

The state of every modulator is saved in those cases. If you need to store other data (memoryBlocks, variables…) you need to use “Called when Ctrlr state is saved” to store data and “Called when Ctrlr is loaded” to retrieve data.
