Understanding MIDI Keyboards
To fully appreciate the role of aftertouch in MIDI keyboards, it's important to first understand the basics of these essential music production tools. MIDI keyboards are highly valued by music producers for their versatility and integration with digital audio workstations (DAWs).
Introduction to MIDI Keyboards
A MIDI keyboard, also known as a controller keyboard, is a piano-style electronic musical keyboard used to send Musical Instrument Digital Interface (MIDI) commands to other musical devices or computers. This can be done over a USB or a traditional 5-pin MIDI cable. MIDI keyboards do not produce sound on their own but act as controllers that manage software instruments and other MIDI-compatible devices.
Some MIDI keyboards are integrated with a sound module, allowing them to produce sound without the need for external devices. This makes them incredibly versatile in both live settings and studio environments.
Most MIDI keyboards feature a range of controls aside from keys, such as knobs, sliders, and pads, which can be assigned to various parameters in a DAW. This makes them highly customizable, enhancing their suitability for intricate music production tasks.
Functionality of MIDI Keyboards
MIDI keyboards serve primarily two functions: sending MIDI commands and controlling software instruments. This includes note on/off commands, velocity (the force with which a key is pressed), and other control signals such as modulation and pitch bends. These functions are crucial for dynamic play and creating expressive music compositions.
| Function | Description |
|---|---|
| Note On/Off | Sends signals when keys are pressed or released. |
| Velocity | Measures the force used to press the keys. |
| Modulation | Controls specific parameters like vibrato or filter cut-off. |
| Pitch Bend | Smoothly varies the pitch of the note being played. |

Digital and analog hardware keyboards like digital pianos, stage pianos, and synthesizers can also be used as MIDI controllers if they possess MIDI capability. However, these might not offer the same level of software integration and number of MIDI-mappable controls as a dedicated MIDI keyboard.
MIDI keyboards are commonly utilized by a broad range of individuals, from hobbyists to professional musicians, in various settings, including home studios, recording studios, and concert stages (Wikipedia). Their integration with DAWs and software instruments makes them indispensable for modern music production.
Understanding the core functionalities of MIDI keyboards gives a foundation for appreciating the advanced features, such as aftertouch, that further enhance their capability and versatility in music production.
Importance of Aftertouch in Music Production
Aftertouch enhances the expressive capability of MIDI keyboards, offering musicians a means to infuse their performances with greater dynamism and nuance.
Aftertouch Explained
Aftertouch, an often overlooked feature of the MIDI protocol, allows musicians to adjust the pressure applied to the keys or pads after initially striking a note, altering the sound produced via MIDI control change (CC) messages (eMastered). This capability enables the modulation of various sound parameters, such as vibrato, volume, and pitch, providing a more organic method of sound manipulation compared to post-recording edits in a digital audio workstation (DAW).
When a key is pressed down, the initial force sends a velocity signal, but continued pressure after the initial strike—known as aftertouch—enables further alteration of the sound. Using aftertouch, musicians can create more expressive and dynamic performances, crucial for both live and studio settings.
Types of Aftertouch
Different types of aftertouch offer varying levels of control and expressiveness. Each type has its own set of applications and benefits.
Channel Aftertouch
Channel aftertouch, also known as monophonic aftertouch, applies the pressure data to affect all notes being played on the same channel uniformly. This means that applying pressure to one key will result in the same modulation effect on all keys currently being pressed.
| Feature | Description |
|---|---|
| Affects | All notes on one channel |
| Control | Uniform modulation |
| Usage | Simpler effect, less hardware complexity |
| Example | Sustain pedal effect |
Polyphonic Aftertouch
Polyphonic aftertouch, or poly pressure, allows each key to send its own individual pressure data. This type of aftertouch provides a higher degree of control and expressiveness, as different keys can modulate parameters independently.
| Feature | Description |
|---|---|
| Affects | Individual keys |
| Control | Independent modulation for each key |
| Usage | Complex, more expressive sounds |
| Example | Different vibrato rates on multiple notes |
However, polyphonic aftertouch tends to be more expensive and less common due to the complexity of required hardware.
In summary, channel aftertouch is ideal for simpler, uniform modifications, while polyphonic aftertouch offers detailed and nuanced control, catering to more complex and expressive performances. Understanding these two types is essential when selecting a MIDI keyboard with aftertouch for music production.
