Midi note to pd number chart1/3/2024 Computer keyboards are not velocity sensitive, if you are using your computer's keys to play notes into a software sequencer, all the notes will have the same velocity. Something to remember- not all keyboards are velocity sensitive, if you hear no difference in the sound produced by a keyboard no matter how hard you hit the keys, then you are not sending variable velocity information from that instrument. For example, a violin playing quick, staccato notes has a must faster attack than longer, sustained notes. Attack is a measurement of how long it takes for a sound to go from zero to maximum loudness. Higher velocity may also shorten the attack of a MIDI instrument. Sometimes different velocities also create different timbres in an instrument for example, a MIDI flute may sound more frictional at a higher velocity (as if someone was blowing into it strongly), and more sinusoidal/cleaner sounding at lower velocities. " Velocity" is a number between 0 and 127 that is usually used to describe the volume (gain) of a MIDI note (higher velocity = louder). You can see that MIDI note 60 is middle C (C4). I've copied the table in fig 2 from NYU's website, it lists all the MIDI notes and their standard musical notation equivalents. " Note" describes the pitch of the pressed key with a value between 0 and 127. This message consists of two pieces of information: which key was pressed (called "note") and how fast it was pressed (called "velocity"). When a key is pressed the keyboard creates a " note on" message. These messages may be routed to a digital synthesizer inside the keyboard, or they may be patched to some other MIDI instrument, like your computer. The most common tool used to generate MIDI messages is an electronic keyboard.
