Boss DR-220
The Boss DR-220 Dr. Rhythm is a series of two budget-priced digital drum machines developed and manufactured by Boss Corporation (a subsidiary of Roland Corporation) beginning in 1985. Origin The DR-220 derives from the earlier DR-110 (1983) without rotary controls but the same LCD "matrix" display panel, a much simplified version of that used in devices such as the Roland TR-707. Logic architecture Each DR-220 has 11 pulse-code modulation (PCM) synthesizer "voices" available, plus an Accent; each voice is directly available for realtime play using the four-by-three grid of miniature pads (though these do not sense either velocity or pressure). The voices are in 12-bit resolution, each occupying a 128 KB Read-only memory (ROM) bank. Because of "channel sharing" restrictions due to circuitry limitations, some voices cannot be sounded simultaneously; for instance, only one tom may be used per beat. With the DR-220, up to 16 steps are displayed (or 12 in 3/4 tempo mode). The "h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Audio
Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit sample depth. Digital audio is also the name for the entire technology of sound recording and reproduction using audio signals that have been encoded in digital form. Following significant advances in digital audio technology during the 1970s and 1980s, it gradually replaced analog audio technology in many areas of audio engineering, record production and telecommunications in the 1990s and 2000s In a digital audio system, an analog electrical signal representing the sound is converted with an analog-to-digital converter (ADC) into a digital signal, typically using pulse-code modulation (PCM). This digital signal can then be recorded, edited, modified, and copied using computers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boss Corporation
Boss is a manufacturer of effects pedals for electric guitar and bass guitar. It is a division of the Roland Corporation, a Japanese manufacturer that specializes in musical equipment and accessories. For many years Boss has manufactured a wide range of products related to effects processing for guitars, including "compact" and "twin" effects pedals, multi-effect pedals, electronic tuners and pedal boards. In more recent times, Boss expanded their product range by including digital studios, rhythm machines, samplers and other electronic music equipment. They also are now manufacturing solid-state amplifiers and speaker heads such as the Waza and the Katana. Both feature multi-effects units meant to emulate Boss' classic effects pedals. History The earliest Boss product was called ''B-100 The Boss'', released in 1974. This came with a clip-on pre-amp and a pickup to amplify acoustic guitars. At this point the Boss company had not been formed and it was still a Beckmen Musi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roland Corporation
is a Japanese manufacturer of electronic musical instruments, electronic equipment, and software. It was founded by Ikutaro Kakehashi in Osaka on 18 April 1972. In 2005, its headquarters relocated to Hamamatsu in Shizuoka Prefecture. It has factories in Malaysia, Taiwan, Japan, and the United States. As of 31 March 2010, it employed 2,699 people.

Boss Doctor Rhythm DR-110
The Doctor Rhythm DR-110 Graphic is a drum machine introduced in 1983 by the Boss product division of the Japanese Roland Corporation. It was the second entry in their DR series, following up on the much simpler DR-55. History Boss were better known for producing electric guitar accessories such as effects pedals, and the DR-110 is similarly small and lightweight in size (190×110×30mm, and only 450 g), and like most Boss equipment, could be run from a 9 V d.c. supply egative centreor batteries. Although not designed as a high-end studio product, The DR-110 nonetheless featured some noticeable advances in technology compared to previous Roland drum machines. It has an LCD graphic display, showing a step-programming grid for the various drum voices. Rubberized touchpads each represent one of the DR-110 voices, and can be used to build a pattern in realtime as well as to enter and edit note data. The DR-110's synthesized drum "voices" (synthesizer sounds) use analog synthesi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roland TR-707
The Roland TR-707 Rhythm Composer is a drum machine released by the Roland Corporation in 1985. Features The TR-707 has fifteen digitally sampled sounds. The instrument is capable of 10-voice polyphony. The alternate bass drum, snare, and hi-hat sounds cannot be triggered simultaneously. The instruments are labeled as Bass Drum, Snare Drum, Low Tom, Mid Tom, Hi Tom, Rimshot, Cowbell, Hand Clap, Tambourine, Hi-Hat (Closed or Open), Cymbal (Crash or Ride), as well as an additional function labeled accent, which serves to rhythmically modify the volume of the other instruments. The instruments on the TR-707 are samples of recordings of actual acoustic instruments, and not synthesized individually like the instruments on the TR-808. The TR-707 provides four levels of shuffle that operate globally on the rhythm, as well as flam that can be applied to any step. The device offers 64 programmable patterns, which are editable via step-write or tap-write, that can be sequenced togeth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse-code Modulation
Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM Stream (computing), stream, the amplitude of the analog signal is Sampling (signal processing), sampled regularly at uniform intervals, and each sample is Quantization (signal processing), quantized to the nearest value within a range of digital steps. Linear pulse-code modulation (LPCM) is a specific type of PCM in which the quantization levels are linearly uniform. This is in contrast to PCM encodings in which quantization levels vary as a function of amplitude (as with the A-law, A-law algorithm or the μ-law, μ-law algorithm). Though ''PCM'' is a more general term, it is often used to describe data encoded as LPCM. A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which i ...

Read-only Memory
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications (like video games) for programmable devices can be distributed as plug-in cartridges containing ROM. Strictly speaking, ''read-only memory'' refers to memory that is hard-wired, such as diode matrix or a mask ROM integrated circuit (IC), which cannot be electronically changed after manufacture. Although discrete circuits can be altered in principle, through the addition of bodge wires and/or the removal or replacement of components, ICs cannot. Correction of errors, or updates to the software, require new devices to be manufactured and to replace the installed device. Floating-gate ROM semiconductor memory in the form of erasab ...

Tempo
In musical terminology, tempo ( Italian, 'time'; plural ''tempos'', or ''tempi'' from the Italian plural) is the speed or pace of a given piece. In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and is usually measured in beats per minute (or bpm). In modern classical compositions, a " metronome mark" in beats per minute may supplement or replace the normal tempo marking, while in modern genres like electronic dance music, tempo will typically simply be stated in BPM. Tempo may be separated from articulation and meter, or these aspects may be indicated along with tempo, all contributing to the overall texture. While the ability to hold a steady tempo is a vital skill for a musical performer, tempo is changeable. Depending on the genre of a piece of music and the performers' interpretation, a piece may be played with slight tempo rubato or drastic variances. In ensembles, the tempo is ofte ...

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, wh ...

CV/gate
CV/gate (an abbreviation of ''control voltage/gate'') is an analog method of controlling synthesizers, drum machines, and similar equipment with external sequencers. The control voltage typically controls pitch and the gate signal controls note on-off. This method was widely used in the epoch of analog modular synthesizers and CV/Gate music sequencers, since the introduction of the Roland MC-8 Microcomposer in 1977 through to the 1980s, when it was eventually superseded by the MIDI protocol (introduced in 1983), which is more feature-rich, easier to configure reliably, and more readily supports polyphony. The advent of digital synthesizers also made it possible to store and retrieve voice "patches" – eliminating patch cables and (for the most part) control voltages. However, numerous companies – including Doepfer, who designed a modular system for Kraftwerk in 1992, Buchla, MOTM, Analogue Systems, and others continue to manufacture modular synthesizers that are increa ...
