Different results between Macro and MS macro command

You don't need the macro at the beginning of the command in the magic sheet.  If this is supposed to be an osc message you also don' need the send string in the magic sheet command.  

The macro interface needs to know what you are doing and if you want to send osc the current solution is the send string command.  The commands in magic sheet are a bit better at understanding osc and as such don't need as much qualifying the osc command.

There is also a local: command you can put before the osc.

If you hover your mouse over the command window it will show you examples.
