I've got a live.observer monitoring the MAIN_MODES of the Launchpad so that I can restrict my device to only talking to the Launchpad when in 'user 2' mode.
When the LP is switched to 'user 2' mode from one of the other modes I need to refresh the button matrix. What I'm finding is that, although I'm sending the right set of messages to the Launchpad it's not updating the matrix. If I manually trigger an update that does work, and I confirmed that it's sending exactly the same messages as the update triggered by switching modes.
After a lot of head-scratching I put a Max delay module between my patcher detecting a switch to 'user 2' mode and the code that updates the Launchpad button matrix. Even a 1ms delay was enough, and the code started working properly.
Now I know to put in there it's not such a big problem but I am puzzled that you can't update the LP when it's already signalled it's in 'user 2' mode.
Anyone else come across this?
