IIRC when atomic == true Data() is expected to contain a single
and complete MIDI message. With atomic == false you could in
theory send a MIDI message in segments perhaps (for a large
sysex dump), but in practice I think the message callback will
not be called for messages sent with atomic == false.

If a member is declared mutable it can be changed by a member
function declared const.

I recommend "The C++ programming language" by Stroustrup.
