All good midi files should have a fantastic intro and a good

ending. One effect that is often used by musicians is fading.

It produces a soft start and end of a song.

Only few sequencers support fade in/out of songs.

My keyboard sequencer has ability to manually play more louder

but automatic fading is not available.

This encouraged me to write a utility that fades a midisong

at given time and velocity parameters.

It is a new challenge for me to handle midi tempo commands

even when it changes anytime in any track.
