So, I finally have the chance to film a project with the 760. I have read so much about it here and only played with it once. But now have a client that wants the zoom... Cool. Well, I have it all hooked up with the mk lanc cable. I am also using the gr-12 to connect (in channel 4). I have it working, zoom works on left stick, although it only works on horizontal. Would like to get the record button to fire on switch one. The mk docs say it defaults to channel 11. My lack of knowledge is vast when it comes to configuring the mx-12. I just want to put the record on switch one and would prefer to get the zoom to move with vertical on the left stick. None of these are show stoppers, just stumped on how to customize the controller. Forgive me if this is a newb question, or painfully obvious.
