Roland XP-50
The Roland XP-50 is a music workstation that combines the synthesizer engine of Roland's JV-1080 sound module with the sequencing capabilities of their MRC-Pro sequencer and a 61-note keyboard. First released in 1995, the XP-50 and the Roland XP-10 were the first two Roland XP-series products, later joined by the XP-80 and XP-30. Sound Engine The XP-50's sound engine utilizes a custom 32-bit RISC chip to accommodate its sound generation and effects processing. There are 640 patches and 128 performances on board. The XP-50's internal memory includes 512 waveforms, which can be expanded with up to four user-installable SR-JV80 expansion boards. Presets include a General MIDI soundset, and a wide selection of sounds, including ambient and techno sounds representative of the time of the XP-50's release. The sample + synthesissound engine's structure consists of "tones," each with a waveform, amplifier, filter, three envelope generators, and a pair of LFOs. Up to four "tones" c ...

Filter (signal Processing)
In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal. Most often, this means removing some frequencies or frequency bands. However, filters do not exclusively act in the frequency domain; especially in the field of image processing many other targets for filtering exist. Correlations can be removed for certain frequency components and not for others without having to act in the frequency domain. Filters are widely used in electronics and telecommunication, in radio, television, audio recording, radar, control systems, music synthesis, image processing, and computer graphics. There are many different bases of classifying filters and these overlap in many different ways; there is no simple hierarchical classification. Filters may be: *non-linear or linear *time-variant or t ...

Polyphonic Synthesizers
Polyphony ( ) is a type of musical texture consisting of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice, monophony, or a texture with one dominant melodic voice accompanied by chords, homophony. Within the context of the Western musical tradition, the term ''polyphony'' is usually used to refer to music of the late Middle Ages and Renaissance. Baroque forms such as fugue, which might be called polyphonic, are usually described instead as contrapuntal. Also, as opposed to the ''species'' terminology of counterpoint, polyphony was generally either "pitch-against-pitch" / "point-against-point" or "sustained-pitch" in one part with melismas of varying lengths in another. In all cases the conception was probably what Margaret Bent (1999) calls "dyadic counterpoint", with each part being written generally against one other part, with all parts modified if needed in the end. This point-against-point conception is opposed to "su ...

Roland Synthesizers
Roland (; frk, *Hrōþiland; lat-med, Hruodlandus or ''Rotholandus''; it, Orlando or ''Rolando''; died 15 August 778) was a Frankish military leader under Charlemagne who became one of the principal figures in the literary cycle known as the Matter of France. The historical Roland was military governor of the Breton March, responsible for defending Francia's frontier against the Bretons. His only historical attestation is in Einhard's ''Vita Karoli Magni'', which notes he was part of the Frankish rearguard killed in retribution by the Basques in Iberia at the Battle of Roncevaux Pass. The story of Roland's death at Roncevaux Pass was embellished in later medieval and Renaissance literature. The first and most famous of these epic treatments was the Old French ''Chanson de Roland'' of the 11th century. Two masterpieces of Italian Renaissance poetry, the ''Orlando Innamorato'' and ''Orlando Furioso'' (by Matteo Maria Boiardo and Ludovico Ariosto respectively), are even further ...

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks. Floppy disk ...

MIDI
MIDI (; Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper ''Universal Synthesizer Interface'' published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and loudness. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, which t ...

Chorus Effect
Chorus (or chorusing, choruser or chorused effect) is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device. When the effect is produced successfully, none of the constituent sounds are perceived as being out of tune. It is characteristic of sounds with a rich, shimmering quality that would be absent if the sound came from a single source. The shimmer occurs because of beating. The effect is more apparent when listening to sounds that sustain for longer periods of time. The chorus effect is especially easy to hear when listening to a choir or string ensemble. A choir has multiple people singing each part ( alto, tenor, etc.). A string ensemble has multiple violinists and possibly multiples of other stringed instr ...

Reverb Effect
A reverb effect, or reverb, is an audio effect applied to a sound signal to simulate reverberation. It may be created through physical means, such as echo chambers, or electronically through audio signal processing. Echo chambers The first reverb effects, introduced in the 1930s, were created by playing recordings through loudspeakers in reverberating spaces and recording the sound. American Producer Bill Putnam is credited for the first artistic use of artificial reverb in music, on the 1947 song "Peg o' My Heart" by the Harmonicats. Putnam placed a microphone and loudspeaker in the studio bathroom to create a natural echo chamber, adding an "eerie dimension". Plate reverb A plate reverb system uses an electromechanical transducer, similar to the driver in a loudspeaker, to create vibrations in a large plate of sheet metal. The plate's motion is picked up by one or more contact microphones whose output is an audio signal which may be added to the original "dry" signal. Plat ...

Low-frequency Oscillation
Low-frequency oscillation (LFO) is an electronic frequency that is usually below 20  Hz and creates a rhythmic pulse or sweep. This is used to modulate musical equipment such as synthesizers to create audio effects such as vibrato, tremolo and phasing. History Low-frequency oscillation was introduced with modular synthesizers of the 1960s, such as the Moog synthesizer. Often the LFO effect was accidental, as there were myriad configurations that could be "patched" by the synth operator. LFOs have since appeared in some form on almost every synthesizer. More recently other electronic musical instruments, such as samplers and software synthesizers, have included LFOs to increase their sound alteration capabilities. Overview The primary oscillator circuits of a synthesizer are used to create the audio signals. An LFO is a secondary oscillator that operates at a significantly lower frequency (hence its name), typically below 20 Hz - that is, below the range of human heari ...

Timbrality
Monotimbral (from the root prefix ''mono'' meaning one, and ''timbre'' meaning a specific tone of a sound independent of its pitch) is usually used in reference to electronic synthesizers which can produce a single timbre at a given pitch when pressing one key (if the synth is monophonic) or multiple keys (if the synth is polyphonic). An electronic musical instrument may be multitimbral, which means it can produce two or more ''timbres'' (also called ''sounds'' or ''patches'') at the same time. Instruments which may be multitimbral include synthesizers, samplers, and music workstations. A multitimbral instrument might be configurable in a variety of ways: *Splitting the keyboard at a given point allows a musician to play, for example, a bass guitar sound with the left hand and a piano sound with the right hand. *Layering timbres allows a musician to play, for example, a pipe organ sound and a string ensemble sound together. *Combinations of keyboard splits and layers may be possib ...
