A class implementing meter changes for output to event streams. While meter allows complex meter divisions, some output formats such as MIDI files do not support this. Slots available in meter:

numerator {integer} | symbol}

The number of beats per measure of the meter. To specify complex meters, use symbols such as 3+2 or 2+3+2.

denominator {integer}

The number of beats (or divisions) per measure of the meter.
