public class Velocity

extends MidiNumber

Velocity is the rate of a keypress or keyrise.

This indicates with how much force the note should be played (where 127 is the most force). It's up to a MIDI device how it uses velocity information. Often velocity is be used to tailor the VCA attack time and/or attack level (and therefore the overall volume of the note). MIDI devices that can generate Note On messages, but don't implement velocity features, will transmit Note On messages with a preset velocity of 64.

A Note On message that has a velocity of 0 is considered to actually be a Note Off message, and the respective note is therefore released. See the Note Off entry for a description of such. This "trick" was created in order to take advantage of running status.

A Logarithmic Scale would be appropriate.

Velocity	CMN
0	Off
1	ppp
3	pp
10	p
32	mp
45	mf
64	f
90	ff
127	fff

Alternate Logarithmic Scale

Velocity	CMN
0	Off
1	pppp
2	ppp
3	pp
5	p
9	mp
15	mf
25	f
43	ff
74	fff
127	ffff
