Vst Sampler Free

[Dallas Querry]

Asampler is an electronic musical instrument that records and plays back samples (portions of sound recordings). Samples may comprise elements such as rhythm, melody, speech, sound effects or longer portions of music.

The mid-20th century saw the introduction of keyboard instruments that played sounds recorded on tape, such as the Mellotron. As technology improved, cheaper standalone samplers with more memory emerged, such as the E-mu Emulator, Akai S950 and Akai MPC.

Samples may be loaded or recorded by the user or by a manufacturer. The samples can be played back by means of the sampler program itself, a MIDI keyboard, sequencer or another triggering device (e.g., electronic drums). Because these samples are usually stored in digital memory, the information can be quickly accessed. A single sample may be pitch-shifted to different pitches to produce musical scales and chords.

Prior to computer memory-based samplers, musicians used tape replay keyboards, which store recordings on analog tape. When a key is pressed the tape head contacts the moving tape and plays a sound. The Mellotron was the most notable model, used by a number of groups in the late 1960s and the 1970s, but such systems were expensive and heavy due to the multiple tape mechanisms involved, and the range of the instrument was limited to three octaves at the most. To change sounds a new set of tapes had to be installed in the instrument. The emergence of the digital sampler made sampling far more practical.

The first commercially available sampling synthesizer was the Computer Music Melodian by Harry Mendell (1976), while the first polyphonic digital sampling synthesizer was the Australian-produced Fairlight CMI, first available in 1979. These early sampling synthesizers used wavetable sample-based synthesis.[8]

During the 1980s, hybrid synthesizers began to utilize short samples (such as the attack phase of an instrument) along with digital synthesis to create more realistic imitations of instruments than had previously been possible. Examples are the Korg M1, Roland U-110, Yamaha's SY series, and the Kawai K series of instruments. Limiting factors at the time were the cost of physical memory (RAM) and the limitations of external data storage devices, and this approach made best use of the tiny amount of memory available to the design engineers.

The 2010s-era music workstation usually uses sampling, whether simple playback or complex editing that matches all but the most advanced dedicated samplers, and also includes features such as a sequencer. Samplers, together with traditional Foley artists, are the mainstay of modern sound effects production. Using digital techniques various effects can be pitch-shifted and otherwise altered in ways that would have required many hours when done with tape.

In Japan, since the 1980s,[citation needed] digital samplers using pulse-code modulation (PCM)[8][unreliable source?] as on the forerunners in the 1970s mentioned above, have been used. The first PCM digital sampler[citation needed] for musical production in Japan may be Toshiba's LMD-649,[10][unreliable source?] created in 1981 by engineer Kenji Murata for Japanese electronic music band Yellow Magic Orchestra, who used it for extensive sampling and looping in their 1981 album Technodelic.[11] The LMD-649 played and recorded PCM samples at 12-bit audio depth and 50 kHz sampling rate, stored in 128 KB of dynamic RAM.[10] The LMD-649 was also used by other Japanese synthpop artists in the early 1980s, including Chiemi Manabe[12] and Logic System.[13]

Usually a sampler is controlled by an attached music keyboard or other external MIDI controller or source. Each note-message received by the sampler accesses a particular sample. Often multiple samples are arranged across the keyboard, each assigned to a note or group of notes. Keyboard tracking allows samples to be shifted in pitch by an appropriate amount, typically in semitones and tones. Each group of notes to which a single sample has been assigned is often called a "keyzone", and the resultant set of zones is called a keymap.

For example, in Fig 1, a keymap has been created with four different samples. Each sample, if pitched, should be associated with a particular center pitch. The first sample (Violin G#2) is distributed across three different notes, G2, G#2, and A2. If the note G#2 is received the sampler will play back the Violin G#2 sample at its original pitch. If the note received is G2 the sampler will shift the sample down a semitone while the note A2 will play it back a semitone tone higher. If the next note (Bb2) is input the sampler will select the Violin B2 sample, playing it a semitone lower than its center pitch of B2.

In general, samplers can play back any kind of recorded audio. Most samplers offer editing tools that allow the user to modify and process the audio and apply a wide range of effects. This makes the sampler a powerful and versatile musical tool.

A sampler is organized into a hierarchy of progressively more complicated data structures. At the bottom lie samples, individual recordings of any sound, recorded at a particular sample rate and resolution. While a common sound to sample is a musical instrument being played (e.g., a pianist playing a piano note or an organist playing a pipe organ), a sample could be any sound, including "non-musical" sounds such as a typewriter clacking or a dog barking. A reference center pitch indicates the actual frequency of the recorded note. Samples may also be "looped" by defining points at which a repeated section of the sample starts and ends, allowing a relatively short sample to play endlessly. In some cases, a "loop crossfade" is indicated, allowing less obvious transitions at the loop point by fading the end of the loop out while fading its beginning in.

Keymaps are arranged into instruments. At this level parameters may be added to define how the keymaps are played. Filters can be applied to change the sound-color while low frequency oscillators and envelope generators can shape the amplitude, pitch, filter or other parameters of the sound. Instruments may have multiple layers of keymaps to play more than one sample at the same time and each keymap may have a different set of parameters so that the incoming note-events affect each layer differently. For example, two layers may have a different sensitivity to the velocity of the incoming note, altering the resulting timbre according to how hard the note is played.

At this level, there are two basic approaches to sampler organization. In a bank approach, each instrument is assigned to a different MIDI channel and multiple banks can be stored to reconfigure the sampler. A different and more powerful approach is to associate each instrument with a patch number or ID so that each MIDI channel can be configured separately by sending controller information on the individual channel.

Some phrase samplers are more optimised for triggering single "one-shot" sounds such as drum hits. Each keymap spans only a single key, requiring a large number of zones (61 on a five-octave keyboard), each with its own settings. "Phrase sampling" aims to simplify this, particularly on interfaces such as the 16 pads on the Akai MPC series: the fact that each pad is actually a note is hidden from the user. The sampling engine does not re-pitch samples, it only plays them back. The user interface is simplified. Phrase samplers often have a groovebox format, which makes them lightweight, easy to operate and light to carry.

Computer Music Inc. was started in New Jersey United States in 1972 by Harry Mendell and Dan Coren. The company was established to develop and market musical instruments based on computer software. The Melodian, developed in 1976,[14][15] was based on Digital Equipment Corporation's PDP-8 computer. It included hand-wired digital-to-analog and analog-to-digital conversion functions, as well as tracking anti-aliasing filters. The Melodian was first used by Stevie Wonder on his album Stevie Wonder's Journey Through "The Secret Life of Plants" (1979).

The Melodian was a monophonic synthesizer with 12-bit analog-to-digital sampling at rates up to 22 kHz. It was designed to be compatible with analog synthesizers and had a feature allowing it to synchronize to the pitch of an analog synthesizer, such as an ARP 2600. This meant that the Melodian captured all frequency modulation effects, including those produced through the ARP's touch ribbon control. It also could trigger off the ARPs keyboard, thus functioning somewhat as a hybrid of sampler and analog synthesizer and making the most of the technology available at the time.

The Fairlight CMI or Computer Music Instrument, released in 1979, started life as the Qasar M8. The M8 was handwired and legend has it that it took two hours to boot up. The CMI was the first commercially available polyphonic digital sampling instrument. The original Fairlight CMI sampled using a resolution of 8 bits per sample,[17] at a rate of 24 kHz, and used two 8-bit Motorola 6800 processors (later upgraded to the more powerful 16/32-bit Motorola 68000).[18] It was equipped with two six-octave keyboards, an alphanumeric keyboard, and an interactive video display unit (VDU) where soundwaves could be edited or even drawn from scratch using a light pen. Software allowed for editing, looping, and mixing of sounds which could then be played back via the keyboard or the software-based sequencer. It retailed for around US$25,000.

Fairlight later released the Series IIx, which increased the sampling rate to 32 kHz[18] and was the first to feature basic MIDI functionality. In 1985, the Series III was released with two significant upgrades: bit rate and sampling rate were increased to CD quality (16 bit/44.1 kHz) and SMPTE time code was now supported. Notable users of the Fairlight CMI include Peter Gabriel, Herbie Hancock, Trevor Horn, Art of Noise, Yello, Pet Shop Boys, Jean Michel Jarre, Duran Duran and Kate Bush. Horn, considered the "Man who invented the eighties", first used his well-known sampling techniques on the album Adventures in Modern Recording, the second studio album released under the name of his project The Buggles. Saying that he was "quite fascinated by Fairlight brass and all of those kind of things that Geoffrey and I had started messing around with before he went off to join Asia", the sampling techniques on Adventures would later be used for records Horn produced like Slave to the Rhythm by Grace Jones, Art of Noise's The Seduction of Claude Debussy and Frankie Goes To Hollywood's Welcome to the Pleasuredome.[19]
