Hey Mate,
Having same "issue", well it is not issue, it is how it is in firmware.
Currently I'm trying to find workaround, I fight with pads to to substitute function but no success in ableton.
How ever I found that you can light up button via sysex messages
Firs button LED (Program change button)
F0 00 20 6B 7F 42 02 00 10 12 7F F7
Just 8 of them (from 1-8) button 9 and 10 (lsb and msb) are somehow "special", and I did not find proper message to light them up.
I would really request Firmware upgrade (I have 1.33), it will help me a lot in live performances.
I'll post video soon.
