Why do MIDI note off messages have velocities?

Asked by: Ryan Peterson

The note off velocity is basically how “hard” you release the key. Like, if you let it up gently or suddenly. Some synthesizers/patches may use this information to change the release, cutting off the sound more gradually or suddenly. Not all MIDI controllers will transmit this.

Does MIDI record velocity?

When you play in performances with a MIDI controller, the software you’re using assigns a value between zero and 127 to each note depending on how hard or soft you hit the key. This parameter is called velocity, and it’s meant to mimic the natural strength variations in our playing.

What information is included in a MIDI note on message?

MIDI message includes a status byte and up to two data bytes. The most significant bit of status byte is set to 1. The 4 low-order bits identify which channel it belongs to (four bits produce 16 possible channels). The 3 remaining bits identify the message.

How do I change my MIDI velocity?

Getting started with how to Change MIDI Velocity in Pro Tools

  1. Double click on the MIDI clip to open the MIDI editor and see the MIDI information: …
  2. Click and drag over the MIDI notes to select them: …
  3. On the top menu bar, click on: Event -> Event Operations -> Change Velocity:

What is MIDI velocity curve?

A velocity curve is essentially a way to customize what MIDI note velocity (between 0 and 127) results from an amount of force with which you play your MIDI controller. Velocity curves allow you to alter the feel of your MIDI controller.

What velocity should MIDI notes be?


Velocity indicates how hard the key was struck when the note was played, which usually corresponds to the note’s loudness (the MIDI velocity range is from 0–127, with 127 being the loudest).

What is note off velocity?

Note-off velocity means the speed with which a pressed-down key is released back up. This information can be used for at least Rhodes electric piano sounds, so that the keys make a different release sound depending on if the keys are released softly or ”hard”.

What is the difference between MIDI channel messages and MIDI system messages?

Different Kinds of MIDI Messages

Channel messages are those which apply to a specific Channel, and the Channel number is included in the status byte for these messages. System messages are not Channel specific, and no Channel number is indicated in their status bytes.

How many degrees of velocity are there?

Some performers feel that the 127 possible values of velocity in the note on message does not provide sufficient resolution to express all of the subtlety of certain large-sample-set instruments (such as large piano sample sets).

Do MIDI channel voice messages contain time related information?

The note will sound until a message to turn off the same note number is received, since MIDI note messages do not include rhythmic durations. Simultaneous events in MIDI must be sent as a string of serial commands.

What are velocity curves?

The force-velocity curve is simply a relationship between force and velocity and can, therefore, be displayed on an x-y graph (Figure 1). The x-axis (i.e. horizontal axis) indicates velocity, for example, this may represent muscle contraction velocity, or velocity of movement (measured in meters per second).

How do you change the velocity on a MIDI keyboard logic?

But of course I want them to be higher. So I can simply drag this to the max. Now now all of these are 127 velocity trick number seven boost your accents.

What is velocity sensitive keyboard?

Velocity sensitivity refers to the mechanism that allows the keys to respond to the force or speed with which they’re pressed. In other words, keys react differently when they’re played in different ways. Playing a keyboard gently will result in softer sounds, while literally playing harder produces more volume.

How do velocity sensitive keys work?

Velocity sensitivity

The piano, being velocity-sensitive, responds to the speed of the key-press in how fast the hammers strike the strings, which in turn changes the tone and volume of the sound. Several piano predecessors, such as the harpsichord, were not velocity-sensitive like the piano.

How do velocity sensitive buttons work?

Usually, velocity-sensitive keyboards have two buttons underneath each key. By having a microcontroller measure the time difference between when each button is pressed, it’s possible to sense how fast each key was pressed.

Are velocity sensitive keys weighted?

Keys are not weighted but are touch sensitive and normal size.

Is touch sensitive better than weighted keys?

Touch Sensitive – No resistance to the touch but the harder you strike the key the louder the tone. Semi-weighted – Lightly weighted. Some resistance but not at all similar to an acoustic piano. Weighted – Feels at least similar to an acoustic piano.

Is touch sensitive keys same as weighted?

No they aren’t. It’s sound vs feel. Touch sensitive means they respond to how much pressure you put on them ( how hard you hit the keys) by increasing the volume of the note making it sound more like a real piano. Weighted means there’s a resistance/ push back that makes it feel more like a real piano.
