Toggle two SysEx strings

[Pulse505]

Hi everyone,

I couldn’t find it anywhere on the forums so I will post my question here.

Is there a simple way to make a toggle button for two SysEx strings.

I want it to be like this
on(1) = F0 41 12 3A 12 70 01 09 01 05 F7
off(0) = F0 41 12 3A 12 70 01 09 00 06 F7

Is this possible whitout LUA?

Kind regards

Hi Pulse,

to my knowledge this is not possible without Lua, but with Lua it is a dead easy task. I will post the code this evening when I’m at home.

Hi Poss, was chatting with Pulse and proposed him to post this question on the forum as I thought that maybe it is possible to use the sysex Midi properties of the component for that. I now how to get the value of the button in the sysex string (explained by Atom in his Getting started doc) but don’t think it is possible to make a calculation on one byte (second to last byte would be 06 – button value).

Hi Pulse, here is the code and instructions I spoke in our chat…

– Check my Step by Step guide for some introduction to Lua and some references
– Open your panel then open Lua editor (in Panel menu)
– Create a method isPanelReady()

--
-- Check if the panel is not busy to load or receiving a program
--
isPanelReady = function()

	if panel:getBootstrapState() == false and panel:getProgramState() == false then
		return (true)
	else
		return (false)
	end

end

– Save and compile
– Create a method Mute_OnChange with luaModulatorValueChange selected in the Initialize from template combo

--
-- Called when a modulator value changes
-- @mod   http://ctrlr.org/api/class_ctrlr_modulator.html
-- @value    new numeric value of the modulator
--
Mute_OnChange = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)

	-- No action if the panel is in bootstrap or program states
	if not isPanelReady() then
		return
	end

	if value==1 then
		-- Mute ON
		msg = CtrlrMidiMessage({0xF0, 0x41, 0x12, 0x3A, 0x12, 0x70, 0x01, 0x09, 0x01, 0x05, 0xF7})
	else
		-- Mute OFF
		msg = CtrlrMidiMessage({0xF0, 0x41, 0x12, 0x3A, 0x12, 0x70, 0x01, 0x09, 0x00, 0x06, 0xF7})
	end
	panel:sendMidiMessageNow(msg)

end

– Save and compile
– Select your toggle and select the Mute_OnChange method in the property Called when the modulator value change

Should work fine 🙂
Good luck!

Hi Goodie, sorry Pulse I was too tired yesterday. I wanted to give you the code now but goodweather was faster. I would have done it the same way, I maybe would have shortended the script to the max like this:

Mute_OnChange = function(mod, value)

 if value==1 then
  -- Mute ON
  panel:sendMidiMessageNow(CtrlrMidiMessage("F0 41 12 3A 12 70 01 09 01 05 F7"))
 else
  -- Mute OFF
  panel:sendMidiMessageNow(CtrlrMidiMessage("F0 41 12 3A 12 70 01 09 00 06 F7"))
 end
end

I only insert checks like isPanelReady() and getBootstrapState() when I run into problems. But it surely is not a bad thing to do it as a preventive measure.

Well, I’m putting isPanelReady in all _OnChange and _OnClick methods otherwise you get soon or later issues…
Also, I’m avoiding putting too many functions in functions even if it works perfectly. More a visual matter and more for code readability.

Now, to shorten even further the code, you can just have everything in one line in fact…

Mute_OnChange = function(mod, value)

panel:sendMidiMessageNow(CtrlrMidiMessage(string.format("F0 41 12 3A 12 70 01 09 %.2x %.2x F7", value, 6-value)))

end

Have a nice w-e 🙂

Thanks for the help guys!

I will have a lot of reading to do now. Let’s get into that LUA. I have 17 different buttons with this functionality to make for my panel 🙂

Kind regards

Hi Goodie, now that’s really short! Very smart, I like short code.

Hey Possemo,

Your code seems to be working very nicely. I don’t know why goodweathers code isn’t working for me but none the less the button is working! 😀

Thanks a lot for the help!

Kind regards

the question is old but maybe someone else will have the same question.
Answer is yes, use msb/lsb in uiButton:

sysex: F0 41 12 3A 12 70 01 09 ms ls F7 (ms = msb, ls=lsb)

button content : value = ms*16 + ls
OFF = 6 (= 0x06 = 0*16 + 6)
ON = 21 (= 0x15 = 1*16 + 5)

Very nice! Didn’t know that!

[goodweather]

Yes indeed! Very good proposal and a new thing I didn’t know 🙂
