uiCombo not responding to MIDI CC

[lfo2vco]

Thanks for the feedback guys,

Possemo, I have taken on board your suggestion regarding the comments, I am currently going though and amending all my scripts putting the comments on a new line. When completed I will test to see what effect this has first, and then if necessary move onto adding the ‘nil’ value between ‘if’ and ‘elseif’ as you suggested.

Diamondamp, thanks for the pointer regarding MIDI messages being overwritten this hadn’t occurred to me. I will try the local variable and see if it makes any difference, once I have completed and tested the changes discussed with Possemo.
Regarding your last post, I have a working method to add bidirectional communication with iuCombos, thus I only required specific bytes of a CC message to achieve this. But thank you for the detailed suggestion and code.

I will report back and let you both know how I get on.

Here is some noise I organised into an acceptable format:

I didn’t knew the list diamondams posted. Yea that’s a nice way to do it. I should study the github page some more – thanks diamondamps.

with the line if midiCcID >= 0xB0 and midiCcID <= 0xBF then... you are checking if the message is a CC (Control Change). This could probably achieved with this:

if midiMessage:isController() == true then...

I don’t know if the syntax is correct but it must be something similar. You could leave the “== true”:

if midiMessage:isController() then...

Github repository is down :/ Good I have a copy.

Hi Guys,

Sorry Daimondamp I didn’t understand what you were posting, my skills in this area are limited so I fumble through with a lot of help from guys like Possemo and yourself.

I noticed the DMCA notice on Roman’s Github page the other day. I thought it was rather crap considering all the effort Roman has put into ctrlr and also taking into account it is non profit software.

One more thing . I think if you want first byte you have to use getByte(1) not getByte(0)
Lua arrays(tables) start at 1 instead of 0.
What i’ve posted are the methods for midiMessage object.
So you can use them as getData()or getByte().
You can check interesting type of message with methods like midiMessage:isSomething()
It will return true or false.

Well, I may have got to the bottom of this issue.

I removed the Index Bootstrap variable from most of my scripts to see what would happen. The result was that I encountered the same error message as was being created by the VST version. This speeded up debugging as I didn’t need to export a VST every time to check the results of my changes. I also noted that it only affected two scripts when I have multiples in a similar format.

Index Bootstrap Variable:

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

First action was to double check that the syntax was exactly the same on the two erroneous scripts as the other non problematic scripts; it was. This lead me leave the coding and look for other possible issues within the panel.

Upon inspection it turned out that one of the scripts was also assigned to a Modulator via the ‘Called when the modulator value changes’ menu. This was obviously wrong as the script is intended to assign a value to a Modulator not vice versa. I corrected this, it worked.

I could not find a similar problem for the other script, however assuming it was a similar problem I renamed it. This also worked, I guess as it broke any possible links to a Modulator via ‘Called when the modulator value changes’.

So now all I have is an issue with pop-up menus that launch at Panel Boot in the VST to sort out, but that is in another thread.

Thanks again for all your help Possemo and Daimondamp.

This does not work:

if midiMessage:isController() then...

Error message:
attempt to call method ‘isController’ (a nil value)

Has someone got this working?

It is a little bit tricky but is working for me :

midiMessageReceived = function(midi)
      ourMidiClassAndMessage= MidiMessage()
      if ourMidiClassAndMessage:isSysEx() then console("sysex") end;
end

Note that midi is not the same as MidiMessage() which is a class

You can check methods of x with what(ourMidiClassAndMessage)

I wonder if we could do the ourMidiClassAndMessage= MidiMessage() part on init only?

EDIT: MidiMessage() object is not working when recive callback is called. It doesn’t contain any data.
Maybe it was half implemented 🙁

Thanks diamondamps. This takes us a step forward. So MidiMessage() does not seem to be accessible via the receive callback. But CtrlrMidiMessage() has some useful options as well. I got it working with this:

midiReceived = function(midi)
  messageType = midi:getType()
  console(tostring(messageType))
end

type 5 seems to be sysex, type 0 seems to be CC. It would be nice if we could find a list that explains the various types.

Edit – another one: programChange is type 7
Edit2 – two more: noteOn = 3, noteOff = 4

lfo to vco you said in a previous message…I have a working method to add bidirectional communication with iuCombos, thus I only required specific bytes of a CC message to achieve this.

I’m interested by your method can you post it?

Also if someone could write a short document with a couple of working example, how to use the bunch function posted higher in this post would be fine for all of us instead to read spreaded part of post to try to understand if what is mention is working or not.

I think a such document would avoid a lot of questions on the forum.

Also why not to create in the forum a special section (Ex:Tutorial) showing samples of working things to help other developers to not reinvent the wheel if someone already found a way to solve particular situations.

This would avoid to dig all the forum to find solutions not spread everywhere.

Thanks from all of us, newbe and others!!!

Stay tuned. Quimquim

Hey there,

OK so I lost my iMac to the current heatwave we are having here in the UK, so at the moment I an computerless. Thus this is not the most up to date version, but it will work.

OK so the following message is attached to the ‘Called when panels receives a MIDImessage’ dropdown in the panel settings.

midiMessageReceived = function(midiMessage)

	-- Controller Byte
	midiCcID = midiMessage:getData():getByte(0)
	-- MIDI Channels
	if midiCcID >= 0xB0 and midiCcID <= 0xBF then

		-- Parameter Byte
		midiCcMod = midiMessage:getData():getByte(1)

		if midiCcMod == 0x08 then
			dcoOneRangeMessage(midiMessage)
		elseif midiCcMod == 0x10 then
			lfoModeMessage(midiMessage)
 		elseif midiCcMod == 0x67 then
			atLevelMessage(midiMessage)

		end

	end

end

So I don’t know how much you know already, so please excuse me if I’m telling you how to suck eggs. This method grabs the MIDI message via midiCcMod, then if midiCcID >= 0xB0 and midiCcID <= 0xBF identifies it as a continuous controller. Then midiCcMod = midiMessage:getData():getByte(1) grabs the parameter byte which identifies which modulator to assign it to. Then if midiCcMod == 0x08 then etc., passes to another method that acts on the modulator. Such as this:

dcoOneRangeMessage = function(midiMessage)

	-- Value Byte
	midiCcData = midiMessage:getData():getByte(2)
	if midiCcData >= 0x00 and midiCcData <= 0x23 then
		DCO1Range:setModulatorValue((0), false, false, false)
	elseif midiCcData >= 0x24 and midiCcData <= 0x53 then
		DCO1Range:setModulatorValue((1), false, false, false)
	elseif midiCcData >= 0x54 then
		DCO1Range:setModulatorValue((2), false, false, false)

	end

end

Here is some noise I organised into an acceptable format:

@diamondamps: thanks for the list

@quimquim: what do you want to do? In general all modulators have bidirectional functionality.

[Quimquim]

Possemo see in the topic “Decode tone from CC32 CC00 PC midi messages” to not mix replys from the actual topic.

Stay tuned. Quimquim

Hi,
I’m just busy to make my first VST versions of my panels and had the problem that no Lua code was launched as dll. Spent the whole afternoon reading the forum about VST preparation.
Found the issue and maybe it will also be interesting for you.

I discovered that we should not have getProgramState() in the condition in the isPanelReady function.
Removing that and thus only using
if panel:getBootstrapState() == false and bPanelLoaded == true then
solves the issue.

I will search further in the forum about the meaning of getProgramState().
All the startup phase of a panel is still a bit cryptic even if I understand it more and more.
