Using velocity to control dynamics is useful for any kind of instrument where you want to be able to change dynamics from one note to the next. No doubt you've seen and used this countless times so it will not require much discussion.
speed with which the key is being hit), the louder the note. Similarly with MIDI the higher the velocity (i.e. The harder you hit a piano key, the louder the note. Think of the principle as being based on a real piano. The most basic and common use for velocity is to control the volume of an instrument. The tools may look different, but the principles are the same. Although all of the examples I'm giving are specific to Logic, the techniques can be applied to any software that allows you to manipulate velocity.
I'll begin by briefly explaining what velocity can be used for and then dive in and show you many various ways velocity can be edited. This tutorial was first published in September of 2009. Every few weeks, we revisit some of our reader's favorite posts from throughout the history of the site.
