Some code that kill ctrlr and hung up windows

[darlock]

Last night i try to made debug panel (based on DEMO – Midi.panel) for sysex transmit and receive from my supernova 2.
I found that toString function dont work. May be becouse supernova transmitted 2 bulk dumps (297 and 99 bytes) at single programm sysex
I try to use char conversion but CTRL was unstable and my PC is hunged.

bugged panel:

2 sysex from 1 program request:

This panel is broken, and i’m afraid you broke it using LUA the wrong way. You need to be careful how you use LUA cause you can damage more that just the panel. If you look at the XML of your panel (just open the panel file in any text editor)
[code:e09wlm5z]
<modulator modulatorValueExpression="modulatorValue" modulatorValueExpressionReverse="midiValue"
modulatorIsStatic="1" modulatorGlobalVariable="-1" modulatorMuteOnStart="0"
modulatorExcludeFromSnapshot="0" modulatorLinkedToPanelProperty="– None"
modulatorLinkedToModulatorProperty="– None" modulatorLinkedToModulator="– None"
modulatorBaseValue="0" modulatorCustomIndex="0" modulatorCustomIndexGroup="0"
luaModulatorValueChange="" modulatorMax="65536" modulatorValue="97"
vstIndex="22" name="lcd_name" uiLabelText="block22" Label text="block111">
[/code:e09wlm5z]
the last property is "Label text" that’s and invalid property and breaks the entire XML document, that causes crashes all over the place. You did this in your lua function assignValues297

[code:e09wlm5z]
panel:getModulatorByName("lcd_name"):setPropertyString ("Label text", "block111")
[/code:e09wlm5z]

i don’t know where you got the "Label text" property name from, but it’s invalid, all the possible properties for each component/modulator/panel are documented in the API DOcs here: api/namespace_ids.html use only those.

Also you declared a LUA method like:
[code:e09wlm5z]
function Sn2 single program dump req ()
end
[/code:e09wlm5z]

you can’t do that, you need to at least grasp the basics of the LUA programming language (no spaces/tabs/newline in any of the variable,object,function names, ever i don’t think a programming language exists that allows this)

Thanks for answers. I wrote my last program more than 6 years ago. I think that i need some practice and good examples to make good ctrlr panels.
I have only one question now.
I tried to load sysex message in uiLCDLabel using yours DEMO – Midi.panel
My code is similar to yours (differs only size of message):
My:
[code:3ev0t66t]midiMessageReceived = function(midiMessage)
s = midiMessage:getSize()
if s == 297 then
out = panel:getModulatorByName("outputLabel")
out:getComponent():setPropertyString ("uiLabelText", midiMessage:toString())
console("received program data")
end
end[/code:3ev0t66t]
Yours:
[code:3ev0t66t]midiMessageReceived = function(midiMessage)
s = midiMessage:getSize()
if s == 300 then
out = panel:getModulatorByName("outputLabel")
out:getComponent():setPropertyString ("uiLabelText", midiMessage:toString())
console("received program data")
end
end[/code:3ev0t66t]

But when device send sysex i`m catch error:
http://www.speedyshare.com/files/30265282/error.jpg

panel:
http://www.speedyshare.com/files/302652 … i_ed.panel

Can you show simple way to display preset names using toString function.
I make some without toString function:
[code:3ev0t66t]pND = midiMessage:getLuaData():getRange(10,15) –extract name of preset
outname = panel:getModulatorByName("lcd_name") –choose component to display
presetname:getComponent():setPropertyString ("uiLabelText", string.char(pND:getByte(0),pND:getByte(1),pND:getByte(2),pND:getByte(3),pND:getByte(4),pND:getByte(5),pND:getByte(6),pND:getByte(7))) — this is my variant of replacement of notworking setPropertyString ("uiLabelText", pND:toString())[/code:3ev0t66t]
I know that string.char is not implemented in ctrlr but this work.

here is an example how you can get the ascii string if it’s encoded in the midi message
[code:3ilam9yx]
mod = panel:getModulatorByName("modulator-1") — first i find my modulator
midi = mod:getMidiMessage() — here i fetch it’s midi message (this will be available in the next build but you can use any MIDI message)
console (midi:toString()) — this is how the message looks like in HEX form
f0 52 6f 6d 61 6e f7

ascii = midi:getLuaData():getRange(1, 5) — i’m interested in 5 bytes starting from byte indexed 1 (second byte)
console (ascii:toString()) — since ASCII conversion is natural, a simple toString() should work

Roman — and there you go, my name in a MIDI Message
[/code:3ilam9yx]

This code (output to console) worked fine but i need to dispaly preset name (extracted from sysex dump) in editor.

[code:38x98niq]presetname = panel:getModulatorByName("labelx")
presetname:getComponent():setPropertyString ("uiLabelText", pND:toString())[/code:38x98niq]

I try to use toString function to assign text to label component and receive error.

Can you provide working example where hex dump is loaded in label as ascii text?

[atom]

i think this error is because the setPropertyString only takes a std::string and the toString() method return a String (internal juce String class), and since LUA does not know about casting i need to fix that, i’ll make it work with the new build. For now you can try
[code:1r7illfy]
text = pND:toString()
presetname:getComponent():setPropertyString ("uiLabelText", text)
[/code:1r7illfy]

I try to use intermediate variable before post my previous post. ” title=”Wink” />
I`m received similar error:
[code:11m70m0q]lua runtime error
[C]:-1(method setPropertyString) no matching overload found,
candidates:
void setPropertyString(CtrlrLuaObject&,std::string
const&,std::string const&)[/code:11m70m0q]

I`m wait next release.

Also i found next bugs:
1. Modulators work wrong when synth transmit NRPN. All modullators that tuned to transmit NRPN (cc99,cc98,cc6) affected by NRPN cc99 cc98.
For example
i used cc99=0 cc98=16 for knob1
and cc99=0 cc98=14 for knob2
My synth receive this perfectly. But when i`m try to rotate knob1 on my synth in panel rotated knob1 and knob2
2. When i use cc or NRPN in modulator and sysex window not empty next time when i`m load panel modulator transmit sysex instead of CC or NRPN

[atom]

1. this is true and i really don’t know if working around it is a good idea, a NRPN is built of 4 (or 3) CC messages so what Ctrlr does is valid, but i understand your problem, i’ll try to work around it but i can’t promise anything really it will be hard

2. i’ll have a look what’s wrong here.

I know this is an old thread, but I was wondering if the API docs are still available somewhere. This link is dead

all the possible properties for each component/modulator/panel are documented in the API DOcs here: api/namespace_ids.html use only those.

You should always look at the methods what() and how()

the how() just print all available regeistered classes

what(object)

prints all available methods on an object, just use it on a modulator/component/whatever and get some answers

[Puppeteer]

I can get what() to run (eg set a push button that runs what(panel))

But how(panel) returns this error

At line [-1]: [C]
What: C
Namewhat: global
Name: class_names
Error message: std::runtime_error: ‘Trying to use unregistered class’

This is my function

WhatMethod = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value)
how(panel)
end

Is that how it’s supposed to be used?

[atom]

Try to use the Lua Console for this like so:

how()
what(panel)[ENTER]

[Puppeteer]

Hi Atom,

how() in the console returns an error

ERROR: std::runtime_error: ‘Trying to use unregistered class’

what(panel) works fine though.

[zeoka]

how(panel:getModulatorByName()) gives wich parameters to put and in wich form.it ‘s like you do a LUA error ,this is the way i use how(). not sure it is correct

[Puppeteer]

Thanks, that works.
