Sampler (musical instrument)

A sampler is a special tool for music.

It can record many kinds of sounds. You can record a piano or a dog bark. It can even record someone talking.

Once you record a sound, you can play it back. You can play these sounds on a keyboard. This lets you turn any noise into music.

You can change how the sounds feel. You can make a sound higher or lower. You can even make a sound play over and over.

Some samplers can play many notes at once. This helps you play big chords. This makes the music sound very full.

Today, many people use them to make songs. They are great for making new sounds. It is a fun way to be a musician.

A sampler is a cool electronic musical instrument.

It works by recording small pieces of sound. These pieces are called samples. A sample can be a melody or a drum beat. It can even be a dog barking or a typewriter clacking.

Once you have a sample, you can play it back. Many people use a keyboard to control the sounds.

You can spread one sound across many keys. This is called a keymap. If you play a high note, the sampler makes the sound higher. If you play a low note, it makes the sound lower.

Early samplers were very expensive. One model cost $30,000! Later, new samplers became much cheaper. This helped more people make music. In the 1980s, the Akai MPC became very famous in hip hop music.

Some samplers can also play many notes at once. This is called polyphony. It helps musicians play big, full chords. Today, samplers are used to make many different sound effects.

A sampler is a versatile electronic musical instrument. It works by recording and playing back small pieces of sound called samples.

These samples can be many things. They might be a melody, a rhythm, or a single note from a piano. A sample can even be a non-musical sound, like a dog barking or a typewriter clacking. Musicians use these sounds to create new music. They can change the pitch to make scales or chords. Many samplers are polyphonic, meaning they can play more than one note at once. They can also be multitimbral, which means they play different sounds at the same time.

Using a sampler involves several steps to shape a sound. First, a user loads or records a sample. This can be done by the user or a manufacturer. Once the sound is in the digital memory, it can be accessed very quickly. A musician might use a MIDI keyboard or electronic drums to trigger the sounds. The user can then use tools to change the sound. They might use filters to change the color of the sound. They can also use effects or modulation to make it unique. Some people use looping to make a short sound play forever. They can even use a loop crossfade to make the transition smooth.

Before digital memory, musicians used tape replay keyboards. The most famous model was the Mellotron. This instrument used analog tape to play recorded sounds. When a player pressed a key, a tape head touched the moving tape. These machines were very heavy and expensive. They also had a limited range of only three octaves. To get new sounds, you had to install a whole new set of tapes. Early digital sampling changed everything. In 1969, Peter Grogono, David Cockerell, and Peter Zinovieff developed the EMS Musys system.

This system used two mini-computers called PDP-8s. It was used to create the piece "Chronometer" in the early 1970s.

Newer machines made sampling more practical for everyone. The first commercial sampling synthesizer was the Computer Music Melodian in 1976. Later, the Australian Fairlight CMI arrived in 1979. It was the first polyphonic digital sampling synthesizer. Early models were very pricey, with the Fairlight costing $30,000. In 1981, Toshiba released the LMD-649 in Japan. Engineer Kenji Murata made it for the band Yellow Magic Orchestra. By 1985, instruments like the Ensoniq Mirage became much more affordable. They cost less than $2,000. In 1987, the E-mu SP-1200 helped make sampling popular in hip hop. The Akai MPC60, released in 1988, became very influential in that genre too.

Samplers link many different types of music together. In the 1980s, hybrid synthesizers used short samples to sound more like real instruments. This helped musicians create very realistic sounds. Today, almost all music workstations use sampling. It is a main tool for making modern sound effects. Whether a musician is in a studio or performing live, samplers are essential. The Ensoniq EPS was one of the first designed specifically for live shows. From tiny drum hits to huge orchestral sounds, samplers help us explore sound. They turn any noise into a musical tool.

A sampler is a versatile electronic musical instrument used to record and play back portions of sound recordings. These recorded segments are known as samples.

A sample can be many different things. It might be a rhythm, a melody, or a speech. It could even be a non-musical sound, like a dog barking or a typewriter clacking. Musicians use these sounds to build complex musical pieces. They can change the pitch of a sample to create musical scales and chords. Many samplers are polyphonic, meaning they can play more than one note at the same time. They are also often multitimbral, which allows them to play different sounds simultaneously.

To understand how a sampler works, one must look at its data hierarchy. At the very bottom are the individual samples. These are recordings captured at a specific sample rate and resolution. A sample might have a reference center pitch to indicate its original frequency. To make a short sound last longer, users can create a loop. This involves defining specific points where a section of the sound repeats. A loop crossfade can make these transitions sound smooth by fading the end out while fading the beginning in.

These samples are organized into keymaps. A keymap is a set of keyzones, which are groups of notes assigned to a single sample. By using keyboard tracking, the sampler shifts the pitch of the sample by semitones as the player moves across the keys.

Users control these instruments through various interfaces. A musician might use a MIDI keyboard, a sequencer, or electronic drums to trigger the sounds. Once a note is received, the sampler accesses the digital memory to play the assigned sample. Beyond simple playback, samplers offer powerful editing tools. Users can apply filters to change the "color" or timbre of a sound. They can also use low frequency oscillation (LFO) to create modulation. This allows for the shaping of amplitude, pitch, and filter settings. These processes allow a single recorded sound to be transformed into something entirely new.

Before digital memory, musicians used analog tape replay keyboards. The most famous example was the Mellotron. In these machines, pressing a key caused a tape head to contact moving analog tape.

However, these systems were heavy and very expensive. They were also limited to a range of only three octaves. To change the sounds, a musician had to install an entirely new set of tapes. The shift to digital sampling made the process much more practical and flexible for creators.

Digital sampling began in earnest with the EMS Musys system. This was developed around 1969 by Peter Grogono, David Cockerell, and Peter Zinovieff. The system ran on two Digital Equipment PDP-8 mini-computers. It utilized 12,000 bytes of core memory (RAM) and a 32k hard drive. This technology was used to realize Harrison Birtwistle's "Chronometer" in the early 1970s. Later, the first commercially available sampling synthesizer arrived in 1976, called the Computer Music Melodian. By 1979, the Australian Fairlight CMI became the first polyphonic digital sampling synthesizer.

This early Fairlight used wavetable sample-based synthesis at an 8-bit audio depth.

The history of samplers is also a history of changing costs and accessibility. Early professional machines were extremely expensive. For example, the Fairlight CMI could cost as much as $30,000. In 1981, Toshiba released the LMD-649 in Japan. This was an early digital sampler that used 12-bit pulse-code modulation (PCM) and 128 KB of RAM. It was used extensively by the band Yellow Magic Orchestra. As technology improved, prices began to drop. The E-mu Emulator brought costs below $10,000. By 1985, the Ensoniq Mirage and the E-mu Emax offered prices under $2,000. This allowed more musicians to use the technology.

Specific samplers helped define entire musical genres. In the late 1980s, the E-mu SP-1200 percussion sampler helped popularize sampling within hip hop music. The Akai MPC60, released in 1988, became one of the most influential tools in that genre. While most samplers were studio tools, the Ensoniq EPS was designed specifically for live performance. Today, sampling is a core part of modern music workstations. It is also a primary tool for Foley artists who create sound effects. From simple playback to complex digital editing, the sampler remains a fundamental part of how we interact with sound.
