MIDI Thru has a special function. It allows the sender to transmit to several receivers. It routes the incoming signal to the next device without modifying it. Another device is simply connected to this jack, thus creating a chain through which the sender can address a number of receivers. Of course it is desirable for the sender to be able to address each device individually. To achieve this, a MIDI channel message is sent with each MIDI event.

MIDI Channel

This is a very important element of most messages. A receiver can only respond to incoming messages if its receive channel is set to the same channel as the one the sender is using to transmit data. Subsequently, the sender can address specific receivers individually. MIDI Channels 1 through 16 are available for this purpose.

MIDI Clock

The MIDI Clock message transmits real-time tempo information to synchronize processes among several connected devices, e.g., a sound generator’s delay time to a MIDI sequencer.

Modulation

A modulation influences or changes a sound-shaping component via a modulation source. Modulation sources include envelopes, LFOs or MIDI messages. The modulation destination is a sound-shaping component such as a filter or a VCA.

Note On / Note Off

This is the most important MIDI message. It determines the pitch and velocity of a generated note. A Note On message will start a note. Its pitch is derived from the note number, which can range from 0 to 127. The velocity lies between 1 and 127. A velocity value of 0 is equivalent to a "Note Off" message.

Normalize

Normalize is a function to raise the level of a sample to its maximum (0 dB) without causing distortion. This function automatically searches a sample for its maximum level and consequently raises the entire sample’s level until the previously determined maximum level reaches 0 dB. In general this results in a higher overall volume of the sample.

Panning

The process or the result of changing a signal's position within the stereo panorama.

Pitchbend

Pitchbend is a MIDI message. Although pitchbend messages are similar in function to control change messages, they are a distinct type of message. The resolution of a pitchbend message is substantially higher than that of a conventional Controller message. The human ear is exceptionally sensitive to deviations in pitch, so the higher resolution is used because it relays pitchbend information more accurately.

Program

A Program is a file that contains a list of all samples to be used, and settings for each sample (i.e., pad assignments, loop points, pitch tuning, effects, etc.) The MPC’s PROGRAM EDIT mode is where you can edit and assign samples. The MPC software can have a total of 128 programs in a Project.

MPC specifications

The Akai MPC, or Music Production Center, has become a legendary piece of equipment in the realms of music production and performance. Originally conceived in the late 1980s, the MPC has evolved through various models, maintaining a core philosophy of combining sampling, sequencing, and beat-making capabilities. Its versatility has made it a staple for musicians across genres, from hip-hop to electronic music.

One of the defining features of the Akai MPC is its drum pad interface. The pads are highly responsive and velocity-sensitive, allowing for expressive drum programming and live performance. The tactile feedback of the pads has earned the MPC a reputation for being intuitive and user-friendly. Artists can create intricate rhythms and beats simply by tapping the pads, making it a favorite for both studio work and live shows.

The MPC utilizes a powerful sampling engine that enables users to capture sounds and manipulate them in real-time. This includes features like time-stretching, pitch-shifting, and layering, which allow for creative sound design. The ability to import and export audio files enhances its utility, making the MPC a versatile tool for music production.

Another key technology in the MPC lineup is its sequencer. The sequencer is capable of handling complex arrangements, providing artists with a flexible platform to construct their compositions. The ability to record and sequence MIDI makes it easy to integrate external instruments, allowing musicians to expand their sonic palette.

Modern iterations of the MPC, such as the MPC Live and MPC X, incorporate advanced technologies including touchscreens, built-in effects, and standalone functionality. This means that users can create music without the need for a computer, making it a portable solution for on-the-go production. The inclusion of Wi-Fi connectivity and MIDI over USB further enhances its compatibility with other devices and software.

The Akai MPC also features robust storage options, including SD card support, enabling artists to save and organize their projects with ease. This is essential for producers who work with large sample libraries or engage in extensive live performances.

In summary, the Akai MPC stands out due to its combination of intuitive drum pads, powerful sampling and sequencing capabilities, standalone functionality, and modern connectivity options. Its impact on music production is undeniable, shaping the way artists create and perform music in contemporary settings. As technology continues to advance, the MPC is likely to remain at the forefront of the music production landscape, inspiring new generations of musicians.
