simple lua combobox sysex

[howidoo]

hi everyone
I want to make a simple combox for example:

Reverb
Hall1
Hall2

every setting has a different sysex string i want to send via lua.
May someone can show me how to write this. That would be great.
I found this code but it doesnt work

`
-- Called when a modulator value changes
-- @mod http://ctrlr.org/api/class_ctrlr_modulator.html
-- @value new numeric value of the modulator

rev = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)

if
combobox == 1 then
SendMIDINow(F0 43 10 4C 02 01 00 10 00 F7)
elseif
combobox == 2 then
SendMIDINow(F0 43 10 4C 05 01 00 10 01 F7)
end`

thanks for your help

Hi, please try this one instead ;-)

--
-- Called when a modulator value changes
-- @mod http://ctrlr.org/api/class_ctrlr_modulator.html
-- @value new numeric value of the modulator

rev = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)

-- No action if the panel is in bootstrap or program states
if panel:getBootstrapState() == true or source==6 or source==1 then
	return
end	

msg = CtrlrMidiMessage({0xF0, 0x43, 0x10, 0x4C, 0x02, 0x01, 0x00, 0x10, value, 0xF7})
panel:sendMidiMessageNow(msg)

end

hey thanks for your replay. The code worked :)
But I need to change more then one value, Is it possible to change msb and lsb with the combobox

F0 43 10 4c 02 01 00 02 00 F7
F0 43 10 4c 02 01 00 03 01 F7

thank you

Everything is possible : )
... 02 00 ...
... 03 01 ...
... 04 02 ...
... 05 03 ...

Is the scheme always the same like ...MSB+1, LSB+1... ? If so

msg = CtrlrMidiMessage({0xF0, 0x43, 0x10, 0x4c, 0x02, 0x01, 0x00, value+2, value, 0xF7})
panel:sendMidiMessageNow(msg)

It works when i use buttons and send the full sysex string. I also tried
F0 43 10 4c 02 01 00 LS MS F7 without Lua
and write for instance: Hall2=257 in the combobox. But when i look at the Midimonitor it sends RAW:[f0 43 10 4c 02 01 00 01 02 f7] not RAW:[f0 43 10 4c 02 01 00 01 01 f7]

Here is a panel that doesn't use lua.

The sysex formula is F0 43 10 4C 02 01 00 MS LS F7 and the combo contents are:

NO EFFECT=0
HALL1=128
HALL2=129
ROOM1=256
ROOM2=257
ROOM3=258
STAGE1=384
STAGE2=385
PLATE=512
WHITE ROOM=1280
TUNNEL=1408
BASEMENT=1664

Here is a panel that uses lua.

The code is:

send_reverb = function(--[[ CtrlrModulator --]] mod --[[ number --]], value --[[ number --]], source)

    local bi = BigInteger(mod:getValueMapped())
    local msb = bi:getBitRangeAsInt(7, 14)
    local lsb = bi:getBitRangeAsInt(0, 7)
    local sysex = string.format("F0 43 10 4C 02 01 00 %.2x %.2x F7", msb, lsb)
    local m = CtrlrMidiMessage(sysex)
    panel:sendMidiMessageNow(m)

end

---

You could also use a lua lookup table in the function mapped to value.

send_reverb = function(--[[ CtrlrModulator --]] mod --[[ number --]], value --[[ number --]], source)
    local t={[0]=0 ,128 ,129 ,256 ,257 ,258 ,384 ,385 ,512 ,1280 ,1408 ,1664}
    local bi = BigInteger(t[value])
    local msb = bi:getBitRangeAsInt(7, 14)
    local lsb = bi:getBitRangeAsInt(0, 7)
    local sysex = string.format("F0 43 10 4C 02 01 00 %.2x %.2x F7", msb, lsb)
    local m = CtrlrMidiMessage(sysex)
    panel:sendMidiMessageNow(m)

end
