I need a ‘delete clip’ function which ofcourse doesn’t exist. I use the shell object to send the ‘delete’ key to application live – which works well but I must be 100% that in LIVE there is indeed just a clip selected before I send the ‘delete’ key. (For example if a track was selected in Live, and i sent the delete key, it would all end in tears and unimpressed audiences)

So I do some checks before I send the delete key command, in Max for Live. This is what it does:
1) Checks that a clip is selected (by verifying the ‘detail_clip’ Id is not “Id 0″)
2) focus the view on ‘session’ (by calling a function)
3) They I wait (currently 300ms) – but I want to get rid of this step

Next send the delete key.

I want to be 1000% sure that the right view is in focus, and just a clip selected. So now I just give it a lot of time and hope it’s enough for the execution of the commands. But much rather I’d have the feedback from Live ‘yes.. this action has been executed’ so I can make the whole delete function a lot faster.[

is there a way to know when the function has been executed so I can proceed??

hope this makes sense!
