Change Midi Speed, Change duration of Midi file

This tool can adjust the playback speed of MIDI files to become faster or slower. Therefore, the duration of the MIDI file is also changed. Some players can adjust the playback speed. But sometimes you need to change the MIDI file between. You can change MIDI files in batches.

For the “Speed” options, you can enter 0.1 to 16. If it is greater than 1, it will become faster, such as 3, which is 3 times faster. If it is less than 1, it will become slower, such as 0.5, which is 1 time slower. If it is equal to 1, it does not change.
