have a midi transport that sends a midi clock signal plus masterclock and it is used as a control in more than one place with or without patches that have it also

to get them to not trigger each other when you start from one transport ,
send $0-masterbpm to where $0-masterbpm is needed in the patch then send out also plain old master bpm. this way if you want to start and stop  the clock from multiple places you can.  i probably ought to put back on the thinking cap about the matters but it worked to not  start up 2 clocks for me when having 2 transports
