I'm interested,... but the LED window is way to small for me. So I don't think this is an option for me, although I understand the feeling about the shining through the neighbour knobs.
Last weekend I did my first gig with the sequencer, There was a lot of smoke, lasers and other flashing lights and I totally loved the big coloured buttons, it felt very sturdy/secure! So obvious what you are doing :)...
