Otherwise, a song is played faster than expected in some cases.

For instance, we assume that 40 pan control change (CC#10) messages are
expressed in 12.5ms each,
 * Prior art omits fractions, i.e. 12ms + 12ms + ... = 480ms.
 * Proposal technique saves fractions, i.e. 12ms + 13ms + ... = 500ms.
Ideal duration is 500ms. So, the proposed method is better than prior one.
