I need to monitor the existence of clips in a 16 Track x 4 Clip grid. This will be used to control status LEDs on a floorboard, either by cc or note, doesn't matter. I know how to do this w/ live.observer, or perhaps by iterating through the tracks/clips and checking for id=0. My (limited) experience is that the live.observer route is strewn w/ deferlow potholes, especially in light of the fact that this is part of a much bigger device (a looper) that has a lot going on api-wise. I suspect there might be some tricky timing issues re: scanning through the 64 clips for id=0, etc. It seems to me that the framework/midiRemoteScripts must already have this functionality since all the "grid-style" controllers seem to have bidirectional communication with the Live clip grid. I don't know any python, but do I have to? Anyone been down this road who can advise on the wisdom of these various approaches? Needless to say, it has to be robust, since it is for live performance. Really appreciate any insight. Thanks, and Merry Christmas.
