Define a sequence of commands to control other machines.
Numbers(s) are the node numbers, the command shall sent to.
The commands 'on'/'off' are used for machines and other nodes.
2018-03-19 21:45:08 +01:00
Offset is the time to the next line in seconds (1..999).
2018-03-10 22:14:57 +01:00
If endless is set, the Sequencer restarts again and again.
The command ' ' does nothing, only consuming the offset time.
