I made a special config for the Launchpad mk2 to use with a 4 track song
It has a 4*8 gridpie, 4 solo, 4 mute, 4 track select, transport and a mini keyboard, plus dedicated pads for the repeater.
i made it cause i wanted all those functions on a single layer without switching configurations (playing a live set wtih 4 instruments /tracks)
If anyone 's interested i can share it.
Please do share it!
