Midi Channel (0y or yy) in LUA

[m.tarenskeen]

What’s the LUA code to get the value of the MIDI channel that is set in the MIDI->Output->Channel menu in Ctrlr?

In the sysex editor in the properties window in my Panel I can do something like
FO 42 3y 31 10 24 F7 (just an imaginary example) where y is the MIDI channel value between 0x00 and 0x0F – if I understand correctly. Correct me if I am wrong.
Now I need to construct a similar SysEx string in my LUA code.

What’s the LUA version of this y variable?

I solved this by adding a method that I use with “called when a MIDI channel changes for a panel”, using the values that are automatically passed as arguments there and storing the channel number in a global variable.
Works for what I want to do.

Yes, I do the same.
Only issue : you don’t get the initial value after Ctrlr is launched and restores the previously selected value.

panel:getPropertyString(“panelMidiOutputChannelDevice”)

Thanks. I knew it had to be something like that! But rather than asking friendly and skilled Ctrlr/Lua users in this forum to tell me things like this I’d rather know where I can find such information myself?

Just open or create a new panel. Enter Edit mode. To the right you have the panel properties. Click on tab “Utility”. There’s the list of all panel variables. The same with every modulator.

Thanks dasfaker!
I have used the feature a lot while working on the newest version of my Korg DS-8 editor.
The DS-8 has a Multi FX section. There are 6 parameters/knobs. But both the function, visible name, and even SysEx command for 5 of the 6 parameters changes when the first parameter (which selects the Effect mode) is changed. This needed some serious Lua+Ctrl magic to get right 🙂
Now in the Panels download section for who is interested.
