AFAIK a timestamp can only be prepended an OSC-bundle (which contains
OSC messages or recursively bundles again), but not a single message?
so the only way to set a certain execution time is by sending a
bundle:
#bundle <timestamp> <sizecount> /midi/<channel>/ and so on...
there is another way if we use the "timetag" data type, which is also
defined:
/midi/<channel>/noteon <pitch> <velocity> <timetag>
but then the timetag information is defined by the semantics of the
OSC address (AKA channel), not by the protocol.

i could not found any hint about the license of matt wright's library,
he always says "OpenSource", which is not necessarily "free". will
ask him about this.
