Eng:Change Tempo by () (block)

The Change Tempo by  block is a Sound block and a Stack block. The block changes the project's tempo by the specified amount. Changing the tempo affects how long the Play Drum for  Beats block and the Play Note  for  Beats block will play, due to the tempo affecting the length of a beat.

Example Uses
As this block changes the tempo (which determines how long each beat is), it is mainly used to speed up and slow down the Play Drum for  Beats block and the Play Note  for  Beats block.

Some common uses for the Change Tempo by block:
 * Changing the speed of songs made with the Sound blocks
 * A music mixer
 * In a project, using a record player and setting the speed of the music to match the speed of the needle

Workaround
The block can be replicated with the following code:
