This duration is decreased by one. As long as it still has +// not reached zero, the only thing that can happen is that the note is turned +// off depending on manual or automatic note spacing. Once the duration reaches +// zero, a new set of musical opcodes are executed. +// +// An opcode is one byte, followed by a variable number of parameters. Since +// most opcodes have at least one one-byte parameter, we read that as well.
