faust2faustvst [midi:clock] [midi:start] [midi:stop] not working

[timpauli]

Hi,

thanks a lot for creating Faust. It is of great help.

When I use [midi:clock], [midi:start] or [midi:stop] with the faust2faustvst command. None of these are working.
For example the following simple code is not working as expected:

import("stdfaust.lib");
play = checkbox("ON/OFF [midi:start] [midi:stop]");    
process = os.osc(440) * play;

I would expect it to play the sine, when I hit the start button in my DAW and be silent when stopping the transport.

This is also connected to #357

Thanks a lot
Best
Tim
