Send simple CC# value when changing tabs.

[Synthetech]

Hey all again,

Well I’ve been away so long that I’ve kinda forgotten how to use LUA/Ctrlr and could use some help again.

I want to call a method when I change tabs.
When I click on
Tab 0,
I want to send Midi Msg “Control Change #95/Value “1”.

Tab 1,
I want to send Midi Msg “Control Change #95/Value “127”.

Tab 2,
I want to send Midi Msg “Control Change #95/Value “2”.

I assume I need to use code like,

— Called when the current tab in an uiTabs component is changed
—

currentTabChanged = function(modulator,currentTabIndex)
console (string.format (“currentTabChanged tabIndex=%d”, currentTabIndex))
l = getComponent(“label-current-tab”)
if l ~= nil then
l:setPropertyString (“uiLabelText”, string.format (“Current tab=%d”, currentTabIndex))
end
end

and somehow put code like this in it..

selectTimber1 = {0xB0; 0x5F, 0x01}
panel:sendMidiMessageNow(CtrlrMidiMessage(selectTimber1))

but I havent messed with code for so long that I am lost in how to do this 🙁

can anyone help me get this to work. I’m hoping it’s very simple and all I need is a push in the right direction to get it to work..
Thanks!

well I managed to dig in again and think I figured it out…

—
— Called when the current tab in an uiTabs component is changed
—

timbreSelect = function(mod, tabIndex)
selectTimbre1 = {0xB0; 0x5F, 0x00}
selectTimbre2 = {0xB0; 0x5F, 0x7F}
selectTimbreSync = {0xB0; 0x5F, 0x01}

if tabIndex==0 then
panel:sendMidiMessageNow(CtrlrMidiMessage(selectTimbre1))

elseif tabIndex==1 then
panel:sendMidiMessageNow(CtrlrMidiMessage(selectTimbre2))

elseif tabIndex==2 then
panel:sendMidiMessageNow(CtrlrMidiMessage(selectTimbreSync))

end
end

seems to output the CC msg as needed.. now I just need to verify it on the microKorg soon.
I’m not sure if the above code is the most efficient, but it does appear to work.

Hi!
Yes this should work. I’m using similar code to display some help on the current tab…
You could also allocate your sysex to a single variable (msgTimbre for example) within each “if” then use sendMidiMessageNow outside at the end.
Anyway Lua is executed fast so this won’t make any difference…
Good luck!
