I have this issue.
Im trying to disconnect a component on the launchpad using "call set_launch_button id 0". It works if i bang it or open the device (with a live.thisdevice in it). But it does not work on set startup. I tried everything but i have to open the device in order to execute. I try it on Live 8.3 with max 5.1.9 and on Live 9 with Max 6, with the same result.
Any idea or workaround please.
