Zho:演奏音阶 () () 拍（积木）

The Play Note for  Beats 积木 is a 音效类积木 and a 条形积木. The block will play the specified note with a set MIDI instrument for the specified amount of beats.

Prior to Scratch 1.2, this block used to be called Play Note for  Secs, but was changed because the length of a beat can now be changed with the 演奏速度设为  bpm block.

用法示例
