A song is a programmed sequence of preset patterns or user patterns that are played automatically. A song consists of multiple slots (called "steps"), each of which contains one pattern. The maximum length of a song is 99 steps. The maximum number of songs that can be stored in the MRT-3 is 99. (The actual number of available steps and songs will depend on the number of distinct sounds in user patterns and the number of steps in other songs.) Note that the number of steps is not equal to the number of measures. The length of each step depends on the pattern that is contained in the step. For example, in the song in the above illustration, if the length of the pattern U01 is 2 measures and the length of patterns U02 and U03 1 measure, the song will look as follows:
Step
1 uses pattern U01 and is 2 measures long.
Step
2 uses pattern U02 and is 1 measure long.
Step
3 uses pattern U03 and is 1 measure long.
Step
4 uses pattern U01 and is 2 measures long.
Step
5, the last step in the song, uses pattern U02 and is 1 measure long.
Therefore, the whole song is comprised of 5 steps with a total length of 7 measures.
Besides the pattern number, each song step can contain the following information.
Settings for entire song
•Song kit: Number of kit to be used for entire song
•Master tempo: Tempo information for entire song
Settings for individual patterns
•Tempo change: Information for changing the tempo within the song
•Volume change: Information for changing the volume within the song
It is also possible to not specify a song kit and memorize individual kits for each pattern. In this case, the kit will be switched together with the pattern.
