A means of generating a control signal based on how much pressure is applied to the keys of a MIDI keyboard. Most instruments that support this do not have independent pressure sensing for all keys, but rather detect the overall pressure by means of a sensing strip running beneath the keys. Aftertouch may be used to control such functions as vibrato depth, filter brightness, loudness and so on.
The amount of pressure applied to a key at any given point while the key is being held down. Pressure sensitive keyboard can have varying presure levels WHILE beingheld down.
A feature of a MIDI keyboard that makes a key pressure-sensitive even after the key has initially been pressed.
is a keyboard effect produced by pushing a key down further than the point at which the key's note sounds. Channel aftertouch applies to all currently sounding notes where polyphonic aftertouch effects only the pressed note.
A MIDI control that measures the pressure placed on a key after it is fully depressed. The resultant value can be used to alter the volume, pitch, or timbre of the sound (for example, adding tremolo or vibrato) in real time. Technically, aftertouch is called "channel pressure" since it affects all notes being played on the same MIDI channel. (See "Polyphonic Aftertouch," "Tremolo" and "Vibrato")
1: Continued pressure on an instrument's keys after the initial strike, which may affect the TIMBRE or volume of sustained notes. 2: MIDI MESSAGES that communicate the amount of aftertouch exerted on the keys.
Pressure applied to a synthesizer keyboard after the key is depressed, and used as MIDI data.
A type of control data generated by pressing down on one or more keys on a synthesizer keyboard after they have reached and are resting on the keybed. See channel pressure, poly pressure.
A type of pressure controlled MIDI data determined by how hard you press a key or group of keys on a keyboard AFTER the initial attack. Sometimes called Poly Pressure.
The name used for the method used by synthesizers to detect whether a key is being pressed harder after the initial strike, alternatively known as Pressure Sensitivity.
