Sample-based Synthesizer
Sample-based synthesis is a form of audio synthesis that can be contrasted to either subtractive synthesis or additive synthesis. The principal difference with sample-based synthesis is that the seed waveforms are sampled sounds or instruments instead of fundamental waveforms such as sine and saw waves used in other types of synthesis. History Before digital recording became practical, instruments such as the Welte (1930s), phonogene (1950s) and the Mellotron (1960s) used analog optical disks or analog tape decks to play back sampled sounds. When sample-based synthesis was first developed, most affordable consumer synthesizers could not record arbitrary samples, but instead formed timbres by combining pre-recorded samples from ROM before routing the result through analog or digital filters. These synthesizers and their more complex descendants are often referred to as ROMplers. Sample-based instruments have been used since the Computer Music Melodian, the Fairlight CMI and ...

Subtractive Synthesis
Subtractive synthesis is a method of sound synthesis in which partials of an audio signal (often one rich in harmonics) are attenuated by a filter to alter the timbre of the sound. While subtractive synthesis can be applied to any source audio signal, the sound most commonly associated with the technique is that of analog synthesizers of the 1960s and 1970s, in which the harmonics of simple waveforms such as sawtooth, pulse or square waves are attenuated with a voltage-controlled resonant low-pass filter. Many digital, virtual analog and software synthesizers use subtractive synthesis, sometimes in conjunction with other methods of sound synthesis. Examples of subtractive synthesis A human example The basis of subtractive synthesis can be understood by considering the human voice; when a human speaks, sings or makes other vocal noises, the vocal folds act as an oscillator and the mouth and throat as a filter. Consider the difference between singing "oooh" and "aaah" , a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Synclavier
The Synclavier is an early digital synthesizer, polyphonic digital sampling system, and music workstation manufactured by New England Digital Corporation of Norwich, Vermont. It was produced in various forms from the late 1970s into the early 1990s. The instrument has been used by prominent musicians. History The original design and development of the Synclavier prototype occurred at Dartmouth College with the collaboration of Jon Appleton, Professor of Digital Electronics, Sydney A. Alonso, and Cameron Jones, a software programmer and student at Dartmouth's Thayer School of Engineering. Synclavier I First released in 1977–78, it proved to be highly influential among both electronic music composers and music producers, including Mike Thorne, an early adopter from the commercial world, due to its versatility, its cutting-edge technology, and distinctive sounds. The early Synclavier I used FM synthesis, re-licensed from Yamaha, and was sold mostly to universities. The ...

Loop (music)
In music, a loop is a repeating section of sound material. Short sections can be repeated to create ostinato patterns. Longer sections can also be repeated: for example, a player might loop what they play on an entire verse of a song in order to then play along with it, accompanying themselves. Loops can be created using a wide range of music technologies including turntables, digital samplers, looper pedals, synthesizers, sequencers, drum machines, tape machine An audio tape recorder, also known as a tape deck, tape player or tape machine or simply a tape recorder, is a sound recording and reproduction device that records and plays back sounds usually using magnetic tape for storage. In its present- ...s, and digital delay, delay units, and they can be Programming (music), programmed using computer music software.

Computer Memory
In computing, memory is a device or system that is used to store information for immediate use in a computer or related computer hardware and digital electronic devices. The term ''memory'' is often synonymous with the term ''primary storage'' or '' main memory''. An archaic synonym for memory is store. Computer memory operates at a high speed compared to storage that is slower but less expensive and higher in capacity. Besides storing opened programs, computer memory serves as disk cache and write buffer to improve both reading and writing performance. Operating systems borrow RAM capacity for caching so long as not needed by running software. If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called ''virtual memory''. Modern memory is implemented as semiconductor memory, where data is stored within memory cells built from MOS transistors and other components on an integrated c ...

Polyphonic Synthesizer
Polyphony is a property of musical instruments that means that they can play multiple independent melody lines simultaneously. Instruments featuring polyphony are said to be polyphonic. Instruments that are not capable of polyphony are monophonic or paraphonic. Synthesizer Monophonic A monophonic synthesizer or ''monosynth'' is a synthesizer that produces only one note at a time, making it smaller and cheaper than a polyphonic synthesizer which can play multiple notes at once. This does not necessarily refer to a synthesizer with a single oscillator; The Minimoog, for example, has three oscillators which are settable in arbitrary intervals, but it can play only one note at a time. Well-known monosynths include the Minimoog, the Roland TB-303, the Korg Prophecy, and the Korg Monologue. Duophonic Duophonic synthesizers, such as the ARP Odyssey and Formanta Polivoks built in the 1970s and 1980s respectively, have a capability to independently play two pitches at a time. Thes ...

Physical Modelling Synthesis
Physical modelling synthesis refers to sound synthesis methods in which the waveform of the sound to be generated is computed using a mathematical model, a set of equations and algorithms to simulate a physical source of sound, usually a musical instrument. General methodology Modelling attempts to replicate laws of physics that govern sound production, and will typically have several parameters, some of which are constants that describe the physical materials and dimensions of the instrument, while others are time-dependent functions describing the player's interaction with the instrument, such as plucking a string, or covering toneholes. For example, to model the sound of a drum, there would be a mathematical model of how striking the drumhead injects energy into a two-dimensional membrane. Incorporating this, a larger model would simulate the properties of the membrane (mass density, stiffness, etc.), its coupling with the resonance of the cylindrical body of the drum, and ...

Wavetable Synthesis
Wavetable synthesis is a sound synthesis technique used to create Periodic function, quasi-periodic waveforms often used in the production of musical tones or Musical note, notes. Development Wavetable synthesis was invented by Max Mathews in 1958 as part of MUSIC-N, MUSIC II. MUSIC II “had four-voice polyphony and was capable of generating sixteen wave shapes via the introduction of a wavetable oscillator.” Hal Chamberlin discussed wavetable synthesis in Byte (magazine), Byte's September 1977 issue. Wolfgang Palm of Palm Products GmbH (PPG) developed his version in the late 1970s and published it in 1979. The technique has since been used as the primary synthesis method in synthesizers built by PPG and Waldorf Music and as an auxiliary synthesis method by Ensoniq and Access Music, Access. It is currently used in hardware synthesizers from Waldorf Music and in software synthesizers for PCs and tablets, including apps offered by PPG and Waldorf, among others. It was also ...

Multimedia PC
The Multimedia PC (MPC) was a recommended configuration for a personal computer (PC) with a CD-ROM drive. The standard was set and named by the "Multimedia PC Marketing Council", which was a working group of the Software Publishers Association (SPA, now the Software and Information Industry Association). The MPMC comprised companies including Microsoft, Creative Labs, Dell, Gateway, and Fujitsu. Any PC with the required standards could be called an "MPC" by licensing the use of the logo from the SPA. CD-ROM drives were just coming to market in 1990, and it was difficult to concisely communicate to a consumer all the hardware requirements for using "multimedia software", which mostly meant "displaying video synced with audio on a PC via a CD-ROM drive". The MPC standard was supposed to communicate this concisely, so a consumer buying hardware or software could simply look for the MPC logo and be assured of compatibility. The MPC program had mixed results primarily because of th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sound Card
A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term ''sound card'' is also applied to external audio interfaces used for professional audio applications. Sound functionality can also be integrated onto the motherboard, using components similar to those found on plug-in cards. The integrated sound system is often still referred to as a ''sound card''. Sound processing hardware is also present on modern video cards with HDMI to output sound along with the video using that connector; previously they used a S/PDIF connection to the motherboard or sound card. Typical uses of sound cards or sound card functionality include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection. Sound cards are also used for computer-base ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Music Workstation
A music workstation is an electronic musical instrument providing the facilities of: *a sound module, *a music sequencer and *(usually) a musical keyboard. It enables a musician to compose electronic music using just one piece of equipment. Origin of concept The concept of a music sequencer combined with a synthesizer originated in the late 1970s with the combination of microprocessors, mini-computers, digital synthesis, disk-based storage, and control devices such as musical keyboards becoming feasible to combine into a single piece of equipment that was affordable to high-end studios and producers, as well as being portable for performers. Prior to this, the integration between sequencing and synthesis was generally a manual function based on wiring of components in large modular synthesizers, and the storage of notes was simply based on potentiometer settings in an analog sequencer. Multitimbrality Polyphonic synthesizers such as Sequential Circuit Prophet-5 and Yamaha DX7 we ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Korg M1
The Korg M1 is a synthesizer and music workstation manufactured by Korg from 1988 to 1995. According to ''Sound on Sound'', it is one of the bestselling synthesizers, selling an estimated 250,000 units. Development Korg's chief engineer, Junichi Ikeuchi, led the hardware engineering design of the M1. Whereas previous synthesizers had shipped with sounds chosen for different markets, the Korg chairman, Tsutomu Kato, and his son Seiki decided that their synthesizers should use the same sounds internationally. Korg assembled an international team to develop the sounds for the M1. To create a deep blown bottle sound, the team played a pan flute over a large sake bottle. Features The M1 features a 61-note velocity- and aftertouch-sensitive keyboard, 16-note polyphony with 1-oscillator Programs (or 8-note polyphony with 2-oscillator Programs), a joystick for pitch-bend and modulation control, an eight-track MIDI sequencer, separate LFOs for vibrato and filter modulation, and ADSR ...

Roland D-50
The Roland D-50 is a synthesizer produced by Roland and released in April 1987. Its features include subtractive synthesis, on-board effects, a joystick for data manipulation, and an analogue synthesis-styled layout design. The external Roland PG-1000 (1987-1990) programmer could also be attached to the D-50 for more complex manipulation of its sounds. It was also produced in a rack-mount variant design, the D-550 (1987-1990), with almost 450 user-adjustable parameters. The D-50's capabilities could be modified through the addition of third-party products by Musitronics, most notably the M-EX which made the D-50 multitimbral (the D-50 was bi-timbral) and expanded the patch memory, as well as a chip that improved the D-50's response to incoming MIDI commands. The D-50 was used in popular music by many artists including Jean-Michel Jarre, Prince, Sting, Michael Jackson, Queen, and Enya.
