    Hi,
    I have several groups of buttons defined as radio buttons.
    I want to set one button let’s say ButtonA as a default ON if none of them are ON.

    ButtonA, ButtonB and ButtonC are radio buttons in the same group.
    If ButtonA is ON and I press Button B, then ButtonA switch to OFF and B to ON. Perfect.
    But If Button A is ON and I press A again or, if Button A receives a Midi IN message to OFF, None of the Button from the Group Will be ON, it’s no longer a Radio button stack.
    How do I manage to have a fallback or default button from the group to be ON like Real Radio buttons that you can’t click twice?

    Thanks a lot

    Hi Damien,

    I did something similar in my JD-990 panel, but all in lua:
    ctrlr.org/roland-jd990-super-editor/
    I use similar code for the Tone Switch buttons.

    
    --
    -- Called when a mouse is down on this component
    --
    
    myRadio = function(--[[ CtrlrComponent --]] comp, --[[ MouseEvent --]] event)
    local modName=L(comp:getOwner():getName())
    
    local t={"ButtonA","ButtonB","ButtonC"}
    for _,v in ipairs(t)do
    	panel:getModulatorByName(v):getComponent():setValue(0,false)--set all other modulators to false
    	if v==modName then
    		-- do something
    		panel:getLabel("debug"):setText(v)
    	end
    end
    
    end --f
    

    Not sure if this is what you are after?

    You might have to initialise one of the buttons on startup to make sure one is engaged perhaps.

    Regards,

    Well it becomes difficult when you need to use these buttons as toggle buttons sending MIDI 0/1 or 0/127.

    Here is a more developed version:

    First I have an some initialising code in a function that runs when the panel loads.

    
    --
    -- Called when the panel has finished loading
    --
    -- @type the type of instance beeing started, types available in the CtrlrPanel
    -- class as enum
    --
    -- InstanceSingle
    -- InstanceMulti
    -- InstanceSingleRestriced
    -- InstanceSingleEngine
    -- InstanceMultiEngine
    -- InstanceSingleRestrictedEngine
    --
    init = function(--[[ CtrlrInstance --]] type)
    dontBlock=false
    panel:getModulatorByName("ButtonA"):setValue(1,false)
    panel:getModulatorByName("ButtonB"):setValue(0,false)
    panel:getModulatorByName("ButtonC"):setValue(0,false)
    myGlobal="ButtonA"
    globalValue=127
    end
    

    then a common mouse down function attached to each button:

    
    --
    -- Called when a mouse is down on this component
    --
    
    myRadio = function(--[[ CtrlrComponent --]] comp, --[[ MouseEvent --]] event)
    local modName=L(comp:getOwner():getName())
    dontBlock=true
    if dontBlock then
    local t={ButtonA=75,ButtonB=76,ButtonC=77}
    for k,v in pairs(t)do
    	panel:getModulatorByName(k):getComponent():setValue(0,false)--set all other modulators to false
    	if k==modName then
    	if myGlobal==tostring(k) and globalValue==127 then
    	globalValue=0
    else
    	globalValue=127
    	end
    		-- do something
    		panel:sendMidiMessageNow(CtrlrMidiMessage(string.format("B6 %.2x %.2x",v,globalValue)))
    		panel:getLabel("debug"):setText(k.."\nsending "..string.format("%.2X",globalValue))
    	myGlobal=tostring(k)
    
    	end
    end
    end -- dontBlock
    end --f
    

    Note the change in the t{} table to a hash table:

    Hi Dnaldoog,
    Thanks for the reply, I checked your exemple panel and it’s exactly what I want, same for the one you put on your JD990.
    I saw that on your tone selector in the JD990 you used the method on valueChange and in the exemple panel you assigned the method to onClick

    Can you explain me the difference and the benefits?

    I also cannot manage to make this script work on mine since it’s uiImageButton and not uiButton maybe it’s a bug from ctrlr for mac or my script is wrong, even with a striped down version to check onclick I don’t get anything in the console :

    UnitSelect = function(--[[ CtrlrComponent --]] comp, --[[ MouseEvent --]] event)
    console("Test Script UnitSelect")
    end
    
    

    Here’s my “intended” script:

    --
    -- Called when a mouse is down on this component
    --
    
    UnitSelect = function(--[[ CtrlrComponent --]] comp, --[[ MouseEvent --]] event)
    
    console("UnitSelect is fired")
    
    local modName=L(comp:getOwner():getName())
    console(modName)
    
    local t={"ViButComA","ViButComB","ViButComC","ViButComD"}
    
    for _,v in ipairs(t)do
    
    	panel:getModulatorByName(v):setModulatorValue(false, false, false, false)	-- Set all other modulators to false
    	
    	if v==ViButComA then
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, 0x00, 0xf7})) -- Press Button
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, 0x00, 0xf7})) -- Release Button
    		console("Unit Button Pressed"..toString(v))
    	elseif v==ViButComB then
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, 0x01, 0xf7})) -- Press Button
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, 0x01, 0xf7})) -- Release Button
    		console("Unit Button Pressed"..toString(v))
    	elseif v==ViButComC then
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, 0x02, 0xf7})) -- Press Button
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, 0x02, 0xf7})) -- Release Button
    		console("Unit Button Pressed"..toString(v))
    	elseif v==ViButComD then
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, 0x03, 0xf7})) -- Press Button
    		panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, 0x03, 0xf7})) -- Release Button
    		console("Unit Button Pressed"..toString(v))
    	end
    end
    
    end

    When I assign this script in the value change method it loops like crazy 🙂

    Any clue about what could be possibly wrong?

    I just need 1 shared script by 4 buttons with 4 different messages sent according to the button pressed and the radiobutton feature like in you demo. I am struggling to get this done.

    Thanks a lot

    Damien

    DnaldDoog,
    Don’t worry my friend. I know your post vanished in the abyss but I received it via mail. I’ll check your method tomorrow. My main concern is that “on mouse down” feature doesn’t work properly with images as button, it’s something wrong with the Ctrlr app itself.
    I’ll check and try what you posted.

    thanks a lot!

    Hi Damien,

    It’s probably a bug, but you can’t use mouse down functions with uiImageButtons. The label will pick up the mousedown, but not the main body of the image button.

    What I do sometimes is have an invisible uiButton sitting above in a separate layer. If you do this though, you won’t see the button image changing (like a red light on etc) so if you want all the visuals then you have to use a called when modulator value changes function which means the lua will be always firing ( which could create an infinite loop ) as was discussed here ctrlr.org/forums/topic/lua-scripts-in-positive-feedback-loop/ recently, so a redesign/rethink would be necessary.

    In your code if v==ViButComA then is viButComA a variable set to panel:getModulatorByName(“viButComA “)?

    If it is, then you are comparing a string ‘v’ to an object. Would need to be if v == "ViButComA "

    Also, I don’t think setModulator() can take a boolean – needs to be an integer.

    panel:getModulatorByName(v):setModulatorValue(false, false, false, false) -- Set all other modulators to false

    but better to use:

    panel:getModulatorByName(v):setValue(0, false,)I think

    And also, the if / else is not necessary in that loop, because you are running through each element anyway, so something like:

    
    for i,v in ipairs(t)do
    
    	panel:getModulatorByName(v):setValue(0, false)	-- Set all other modulators to false
    	
    -- not sure about what the above achieves
    	
    panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, i-1, 0xf7})) -- Press Button
    panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, i-1, 0xf7})) -- Release Button
    		console("Unit Button Pressed"..toString(v))
    end

    Hi Damien,

    Here is a panel that might do what you want to do using uiButtonImage.

    Previous post has been blocked again and is awaiting moderation.

    I’ll post it again here:


    This is how to do it using when modulator value changes with uiImageButton. It’s a bit more complicated.
    If I understand the sysex you’re trying to send that is,

    
    UnitSelect = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
    if source==4 then -- should stop this code running on start
    	
    	local n=L(mod:getName())
    	local t={ViButComA=0,ViButComB=1,ViButComC=2,ViButComD=3}
    	
    	for k,v in pairs(t)do
    		if k==n then
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, value*8, t[n], 0xf7}))
    		else
    			
    			panel:getModulatorByName(k):setValue(0,false) -- true can create an infinite loop
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0, v, 0xf7})) 
    			
    		end -- fi
    	end -- for
    	
    end -- source ==4 (user clicked on a button - not lua generated
    end
    

    In an init function:

    
    init = function(--[[ CtrlrInstance --]] type)
    
    panel:getModulatorByName("ViButComA"):setValue(1,true)
    panel:getModulatorByName("ViButComB"):setValue(0,true)
    panel:getModulatorByName("ViButComC"):setValue(0,true)
    panel:getModulatorByName("ViButComD"):setValue(0,true)
    end

    Hi Dnaldoog,

    This is awesome! it’s working perfectly.
    In my case pressing buttons requires 2 messages : pressing (00) and releasing (08), because there is combo with 2 or 3 button pressing at the same time. In the latter case, you have 2 “press” button registered then a 3rd one that defines the task to do like saving banks or switching FX from Unit A or B etc… the implementation of sysex in this DP4 is very complex.

    So the script is :

    UnitSelect = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
    if source==4 then -- should stop this code running on start
    	
    	local n=L(mod:getName())
    	local t={ViButComA=0,ViButComB=1,ViButComC=2,ViButComD=3}
    	
    	for k,v in pairs(t)do
    		if k==n then
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0, v, 0xf7})) -- press button
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, value*8, t[n], 0xf7})) -- release button
    		else
    			panel:getModulatorByName(k):setValue(0,false) -- true can create an infinite loop			
    		end -- fi
    	end -- for
    	
    end -- source ==4 (user clicked on a button - not lua generated
    end

    I wonder were did you get this “source” tag from and since manually is value = 4 I really want to know what other values represent. This is secret weapon.

    I blocked/allowed sending param value on refresh for all the knobs with a statement in my “send message” script :

    -- BLOCK UPDATE IF THE VALUE CHANGE IS FROM AN EDIT BUFFER REQUEST
    if AllowStatusUpdate == 0 then
    	console("Param BLOCKED Because AllowStatusUpdate is OFF")
    else
    	panel:sendMidiMessageNow(CtrlrMidiMessage(m:toHexString(1)))
    end
    

    So the parameter value message bond to the modulators is only sent by hand command.

    And added a mousedown method on every knobs

    
    ParamAllowStatusUpdate = function(--[[ CtrlrComponent --]] comp, --[[ MouseEvent --]] event)
    
    -------------------------------------------------------------------------
    --	BLOCK CTRLR TO SEND PARAM CHANGE AFTER RECEIVING EDIT BUFFER MESSAGE
    --	ONLY PARAM CHANGE FROM MOUSEDOWN ARE ALLOWED
    -------------------------------------------------------------------------
    
    AllowStatusUpdate = 1
    console("AllowStatusUpdare ON via MouseDown on Param Knob")
    end
    
    

    This source == 4 condition will help me a lot cleaning up my script at the final stage.

    Thank you so much for your help and sharing your knowledge, I really improved my logic skills with this project.

    I am sorry I’ve been to fast, I thought this was working… but in fact it wasn’t.

    The radio switching operates properly and the message is sent as well but if the image is clicked twice, the button position can be reset to OFF.
    If the button is ON and clicked a second time it has to stay on and it’s not.

    Check on your demo if you click a button twice, all set to OFF.

    thanks

    Alright, I fixed the issue with a statement based on the current value of the clicked modulator

    It sends the message only if the button was not ON before clicking on it.
    And it locks the position to ON if clicked a second time without sending the sysex message twice.

    
    UnitSelect = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
    if source==4 then -- should stop this code running on start
    	
    	local n=L(mod:getName())
    	local UnitModValue = panel:getModulatorByName(n):getModulatorValue()
    	local t={ViButComA=0,ViButComB=1,ViButComC=2,ViButComD=3}
    	
    	console("Unit Selected Value : "..tostring(UnitModValue))
    
    	for k,v in pairs(t)do
    		if k==n and UnitModValue == 0 then
    			console("Unit Selected : "..tostring(k))
    			panel:getModulatorByName(k):setValue(1, true)
    		elseif k==n and UnitModValue == 1 then
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, v, 0xf7})) -- press button
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, v, 0xf7})) -- release button
    		elseif k~=n then
    			panel:getModulatorByName(k):setValue(0, true)
    
    		end -- fi
    	end -- for
    	
    end -- source ==4 (user clicked on a button - not lua generated
    end
    

    Hope it will help people having trouble with radio buttons like me 😉

    Hi Damien,

    You were right about clicking twice on the button. I could have sworn I had fixed that!

    Anyway, your code works beautifully.

    The only problem now could be updating the radio button array from incoming MIDI, because source==4 will block that too. source==5 will allow lua code to run, but then you would run into problems with the lua creating infinite loops. This source parameter was a recent discovery for me.

    Anyway I am re-posting another panel with your code for other people to look at in the future who might come across this problem.

    Buttons are updated via midi since LUA method do the work. On midiIn update, the source = 5 but still fires the buttons sysex.
    But I don’t wan’t my buttons to send values again on their update via MidiIn so I added a kind of callback value inside my midiReceived script :

    ReceivingBufferEdit = 1 — Block Active Unit Update
    script to update all the parameters on dump reception
    ReceivingBufferEdit = 0 — Allow Active Unit Update

    and on the radio type script I have :

    UnitSelect = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
    if source==4 then  -- should stop this code running on start
    
    console("Source for UnitSelect : "..(source))
    
    if ReceivingBufferEdit==0 then -- Send button values only if they are not updated via Midi dump
    
    	local n=L(mod:getName())
    	local UnitModValue = panel:getModulatorByName(n):getModulatorValue()
    	local t={ViButComA=0,ViButComB=1,ViButComC=2,ViButComD=3}
    	
    	console("Unit Selected Value : "..tostring(UnitModValue))
    
    	for k,v in pairs(t)do
    		if k==n and UnitModValue == 0 then
    			console("Unit Selected : "..tostring(k))
    			panel:getModulatorByName(k):setValue(1, true)
    		elseif k==n and UnitModValue == 1 then
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x00, v, 0xf7})) -- press button
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0x08, v, 0xf7})) -- release button
    		elseif k~=n then
    			panel:getModulatorByName(k):setValue(0, true)
    
    		end -- fi
    	end -- for
    
    end
    	
    end -- source ==4 (user clicked on a button - not lua generated
    
    end
    

    And it’s all good. Thank you for your help

    Excellent!

    I was thinking something like that would be necessary.

    I haven’t really tested this ‘source’ thing too much.

    Should be a good reference post for to others wanting to do this in future, because radio buttons aint easy!

    Regards,

    JG

    This is how to do it using when modulator value changes with uiImageButton. It’s a bit more complicated.
    If I understand the sysex you’re trying to send that is,

    
    --
    -- Called when a modulator value changes
    -- @mod http://ctrlr.org/api/class_ctrlr_modulator.html
    -- @value new numeric value of the modulator
    --
    UnitSelect = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
    if source==4 then -- should stop this code running on start
    	
    	local n=L(mod:getName())
    	local t={ViButComA=0,ViButComB=1,ViButComC=2,ViButComD=3}
    	
    	for k,v in pairs(t)do
    		if k==n then
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, value*8, t[n], 0xf7}))
    		else
    			
    			panel:getModulatorByName(k):setValue(0,false) -- true can create an infinite loop
    			panel:sendMidiMessageNow(CtrlrMidiMessage({0xf0, 0x0f, 0x40, 0x00, 0x00, 0x01, 0x00, 0x02, 0, v, 0xf7})) 
    			
    		end -- fi
    	end -- for
    	
    end -- source ==4 (user clicked on a button - not lua generated
    end
    

    In an init function:

    
    --
    -- Called when the panel has finished loading
    --
    -- @type the type of instance beeing started, types available in the CtrlrPanel
    -- class as enum
    --
    -- InstanceSingle
    -- InstanceMulti
    -- InstanceSingleRestriced
    -- InstanceSingleEngine
    -- InstanceMultiEngine
    -- InstanceSingleRestrictedEngine
    --
    init = function(--[[ CtrlrInstance --]] type)
    
    panel:getModulatorByName("ViButComA"):setValue(1,true)
    panel:getModulatorByName("ViButComB"):setValue(0,true)
    panel:getModulatorByName("ViButComC"):setValue(0,true)
    panel:getModulatorByName("ViButComD"):setValue(0,true)
    end

    Hi JG,
    I am working on a preset popup populated with tables containing the preset names.
    Everything is working perfectly but I have some issues with a statement between label names and what it should equals for the statement to be true.

    It’s a method fired when some labels are clicked :

    
    --  GET THE LABEL CLICKED SOURCE
    	local n = L(comp:getOwner():getName())
    	console ("name of the display label"..(n))
    
    --	MAIN MENU
    		--PstSelectMain:addSectionHeader ("Select Unit Type")
    		if n==lblPrstUA or n==lblPrstUB or n==lblPrstUC or n==lblPrstUD then
    			PstSelectMain:addSubMenu("1 Unit RAM", Algo1UnitRamPreset, true, Image(), false, 0)
    			PstSelectMain:addSubMenu("1 Unit ROM", Algo1UnitRomPreset, true, Image(), false, 0)
    		end
    		if n==lblPrstUA or n==lblPrstUC then
    			console("U2 submenu")
    			PstSelectMain:addSubMenu("2 Unit RAM", Algo2UnitRamPreset, true, Image(), false, 0)
    			PstSelectMain:addSubMenu("2 Unit ROM", Algo2UnitRomPreset, true, Image(), false, 0)
    		end
    		if n==lblPrstUA then
    			console("U4 submenu")
    			PstSelectMain:addSubMenu("4 Unit RAM", Algo4UnitRamPreset, true, Image(), false, 0)
    			PstSelectMain:addSubMenu("4 Unit ROM", Algo4UnitRomPreset, true, Image(), false, 0)
    		end
    		if n==lblProgramName or lblAdditionalInfo then
    			console("Config submenu")
    			PstSelectMain:addSubMenu("Config RAM", ConfigRamPreset, true, Image(), false, 0)
    			PstSelectMain:addSubMenu("Config ROM", ConfigRomPreset, true, Image(), false, 0)
    		end
    
    

    I don’t know why but even if n returns lblPrstUA i.e the statement if n==lblPrstUA is never true.

    My script is alright if I remove all the above statements.

    Thanks for your help, have a nice weekend

    Damien

    Hi Damien,

    You need to surround those if statements with quotes (single or double) else lua is interpreting those as object names.

    if n=="lblPrstUA" or n=="lblPrstUB" or n=="lblPrstUC" or n=="lblPrstUD" then

    In the hash table example local t={ButtonA=75,ButtonB=76,ButtonC=77} ButtonA etc are variable names so no quotes needed. In a regular lua table of elements, you need quotes (unless it is a table of objects) local t={"ButtonA","ButtonB","ButtonC"}

    Regards.


    PS
    Be careful with if n==lblProgramName or lblAdditionalInfo – the second part of the if statement is checking for boolean truth.

    if n=="lblPrstUA" or n=="lblPrstUB" or n=="lblPrstUC" or n=="lblPrstUD" then

    Thank you very much, it makes sense. I changed it and it worked right away, like magic!
    take care

    Damien
