From the forum archives, I see that last December the following bug was confirmed: using the Space bar to play or stop Pro Tools from the VE Pro server does not work when both programs are on the same computer.
I'm having the same issue, but it's with Logic 9.1.7. The menu item works, the transport triangle button works, but space bar doesn't work. Also, remotely on a separate computer, space bar DOES start or stop Logic.
Is this bug confirmed for Logic as well as PT? Many thanks.
