ReaLearn: EN16 / MFT change LED colours with active mapping

[clinkingdog]

Apologies if this is answered somewhere but I have searched quite a lot and couldn't find an answer.

I want to set up ReaLearn with a specific controller to control the FX chain of the currently selected track. Each track would have a ReaLearn instance defining how to interpret the controls for the other FX on that particular track, and I can see that I can activate mappings based on which track is selected. So far so good.

However, I want to be confident about which mapping is currently active, ideally by using RGB LEDs on the controller. I know that it's possible to set colours on the MIDI Fighter Twister - but is it possible to change those colours based on what mapping is active? So far I've only seen a static colour editor and to be honest I didn't totally understand how to use it anyway.

Additional question: Is it possible to set the LED colours on the InTech Studio EN16? I haven't got either device yet and I will decide which one to get based on whether they support this use case. I have seen a lot about ReaLearn's MFT support but less about the EN16.

Thanks!

Yes, you can send MIDI messages when a mapping becomes active. There are multiple ways to do it. The currently best way (if you are not scared by Lua) is to use the MIDI script source. If y (the target value) is nil, you know the mapping is inactive. So you can react to those changes in your script and send the color sys-ex messages as you want.

I can't answer that question. It really depends on the device. If it supports changing colors via MIDI, then yes! If it doesn't, then probably no.

Thanks @helgoboss - actually I posted the question on the Reaper forums and you answered there! I got my MFT set up exactly how I want it and now both the controls and the colours update correctly every time I change track selection. It's wonderful!

Thank you for replying here though - hopefully it will be useful if someone else comes across this issue later.
