Push tempo-related commands only before a note or loop command
Push tempo-related commands only before a note or loop command

Keep track of state changes and push a sequence of commands before a
note or loop command.  This only works with stateless commands, e.g.
note length or quantization length (Octave Command has state in the
player because there's Increment/Decrement Octave Commands).
