Hey digital mike. The BCF2K is a great midi controller for the Compu live software. I have used it and it work perfectly. Unfortunetly I have not had the chance to use the software with a touch screen ever. I hope to change that one day. to answer your questions as I understand them:
1) I don't think the DMX operator would be ideal as a midi or even a external device for control for the compu live program as there is no map for it in the software. This is where I would recommend if you already had a BCF2K to use it instead of the DMX OP.
2) Over the dmx op? Yes.
3) To my knowledge no. But if any other forum users know of any please let us know as we will try to fix it.
Hope this helps and no your post was not that long. I have read longer.
Sincerely,
