The sync between laptops is achieved using Precision Time Protocol. One of the machines must be assigned as a master to which all others will sync. Before the SC patch is evaluated, prepare clock sync in the following way.
Check if master machine is running ntp daemon:
ps waux | grep ntpd
If master is running ntp daemon (regardless if connection to internet is present), run PTPd in master mode:
sudo ptpd -C -G
If master has not ntp daemon, run
sudo ptpd -C -W
All other computers should run PTPd in slave mode:
sudo ptpd -C -g
Now all clocks of all laptops should be in tight sync and the SC patch can be evaluated. It is recommended that it is evaluated just before the performance.
To test the sync, all laptops should play "~white2", which is a short click at frequency 1Hz.
