How do I change the velocity of a single midi note at the very end?

A velocity is how hard/loud the note is played. You can't change the velocity after the note is played (eg you hit a guitar string with a certain force to play a note - you can't then "hit it with less force" half way through the note - it's already been hit.)

 

What you probably want to do is automate the volume of the instrument while the note is playing.

Would you not do it as automation in the piano roll?

No. The velocity value (ONE velocity value) is an attribute of the note event. Velocity means speed, and that value is a measure of how fast you hit the key on the keyboard. Because you hit one note only once, there's only one velocity value for one note (for example, a MIDI Note event will be Note-pitch=C2-Velocity=83). You don't change how fast you hit a key on your keyboard after you've hit the key, so there's no changing the velocity of a note after you've hit the note.

 

It's kind of like measuring how hard you hit a baseball, you don't change how hard you've hit the baseball while the ball has already been hit and is flying through the air — same thing.

Oh, I wondered what the difference between velocity and volume was. Thanks!

I meant volume then. Zipfunk, you are right, the piano roll has its own automation! That should work... how ever, you cannot change the volume of one single note at the end, can you? It affects the whole chord insted

I see. Yes velocity is really a performance measure: how fast the key was traveling downward on the keybed, which pretty much translates to how hard you were hitting the key. Then depending on the instrument that performance nuance may be doing nothing, or changing the volume, or changing other things (sometimes volume and brightness, envelope attack and/or release times etc...).

 

Gianni you're right, the volume automation affects the entire instrument, not individual notes. The only workaround to automating the volume of a single note independently of the others would be to duplicate the instrument track (Command-D) and move that note to the new track.

Hate to confuse things and spoil your simile but what about note off velocity?
