MPK261 lights sysex

Hi clever people of Cantabile.

I’ve got an mpk261 and I’m trying to control the lights on the unit using sysex. I’ve got the pads working great, can change the colour really well. However, I’m also in need of being able to turn the s1-s8 lights on and off as well. Trying to find the combination of address (2 bytes) and on/off switch by trial and error is proving pretty impossible, so I was wondering if any of you have worked it out? I know this is a pretty un-cantabile question, but I found the mpk pad lights rack on here, apologies, I can’t remember who created it, and also it seems Akai customer support is pretty non existent…

Thanks in advance for any help.


It was @BigTwisty who provided the Pads rack, any thoughts?
