The velocity is at the bottom and as you can see on the left it is like a graph with each note having a value between 1 and 127.īut if your MIDI keyboard is too quiet you may want to push the average velocities up so you can hear them more clearly. See below a screenshot of a MIDI piano roll. If you are playing piano, for example, it is likely you will hit some notes harder than others, as a human you are unlikely to hit every single key with the same velocity. Having a range of different velocities throughout a piece of music is usually a good thing because it makes the music sound natural. With 127 being the loudest note and 0 being silence. The controller uses the velocity response to map the velocity to its volume output, and this is where most volume problems lie.Ī midi note velocity is basically a number between 0 and 127. Velocity measures how fast the voltage changes, and it directly corresponds to how fast and hard you press the key. It is this voltage that your MIDI controller converts into audio data. Instead, the key acts as a switch to turn on the voltage in a circuit. It just closes a circuit in the keyboard. However, pressing a MIDI keyboard key makes no sound by itself. Some may also include drum pads and other features, but they all work the same way. These electronic devices let you synthetically produce the sound of any instrument just by pressing keys. This situation is a byproduct of how a MIDI keyboard works. The issue lies in how your MIDI controller software handles inputs coming from the keyboard. When your MIDI keyboard fails to make a sound when you press a key, most of the time the problem is not with your keyboard. How to Adjust a MIDI Keyboard’s Velocity Parameter Therefore, you just have to find the velocity setting controls for your brand of MIDI keyboard and controller. It sets the keyboard’s response to how hard you press the keys.

The velocity parameter is what controls the MIDI keyboard’s output. So, how to fix a quiet MID keyboard? You fix a quiet MIDI keyboard by adjusting the velocity curve parameter of the keyboard in the MIDI settings. Fortunately, fixing a quiet MIDI keyboard is easy if you know the right parameters. It was a large, professional keyboard, but the volume was way too low when I brought it home to test it.

I once bought an excellent MIDI keyboard from a yard sale.
