How to transmit sysex message by changing a tab

[memorysplice]

I am needing to know how to transmit a specific sysex message when I change a tab and how to change the sysex message for each tab. Does anyone have any ideas?

A tab is a modulator so you build a classical OnChange method related to it that you will connect to “Component – Called when current tab changes”
The start of your method is like:

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

value is the tab number. So you can just do something like

if value==0 then
sendmessage0
elseif value == 1 then
sendmessage1
elseif value ==2 then
sendmessage2
end

Is there a way to make a button to get the current tab’s parameters if I made a lua script pertaining to those parameters, the example being a multi-timbral synth?

Sorry, I don’t get you… What do you want to do?
With Lua you can retrieve any property of any modulator, thus including tabs.
Then you can store those in variables or set other modulators with the values or…

Sorry about the phrasing, Goodweather. I was up at 5am after an all night coding binge. What I was thinking of you have 3 tabs for an object with a button that request parameters based on the tab that you are on. How would I go about making it?

[memorysplice]

Never mind about the get button referencing the current tab. I am trying to get the method working using the tab onchange fuction and I am getting elseif errors. can you help with syntax?

[memorysplice]

I found a solution in the demo Panels! Thanks you for your help.

I was going to answer that you can do as follows:

• for your object you need to have some kind of button to trigger the read of the tab params. In that button, you set the OnChange property to a method you will call for example ReadTabParams()
• In ReadTabParams() you need to test the value of your uiTabs modulator using if-elseif-elseif-else-end and you read each property within each else

This should work fine…

Is there a way to do the inverse? Change a tab with an incoming sysex message?

[goodweather]

With a modulator having Midi properties and for example a CC message associated, you can connect an OnChange method as the one I provided above.
As you can see, the last parameter is Source and is a number.
Checking for Source==2 means that the change is coming from the hardware synth.

I’m using this all the time, to change tabs automatically when I’m turning a knob on my Pro2 so that I get the corresponding tab in Ctlr display (see Pro2 panel).

Code is like:

if source==2 then
	panel:getComponent("Pro2Tabs"):setProperty ("uiTabsCurrentTab", 0, false)
end

Replace 0 by the corresponding tab number…

To be tested if it also work when the Midi properties is on Sysex and when the sysex string is matching.
