Split-8
The Split-8 is a polyphonic analogue keyboard synthesizer manufactured by Sequential Circuits. Built in Japan and going by the alternative name Pro-8 in some markets, this was one of the last synthesizers produced by the company and was assigned model number 608. It was released in 1985 at a list price of $1,199 (or $1,195; this number varied between advertisements). This and some other Sequential Circuits synthesizers (the Six-Trak, Multi-Trak and MAX) were built around the Curtis Electronics CEM 3394 "synth-on-a-chip" integrated circuit, and used a Z80 as their central microprocessor. Features and Cabinet Brief Summary of Features This electronic keyboard is an 8-voice polyphonic, bi-timbral analogue synthesizer with the ability to split or layer two sounds ("double" mode). It has 64 memory locations for sounds (" patches"). Patches may be "linked" in memory so that calling up one automatically calls up the second for a split or layer.

Sequential Circuits
Sequential is an American synthesizer company founded in 1974 as Sequential Circuits by Dave Smith. In 1978, Sequential released the Prophet-5, the first programmable polyphonic synthesizer; it became a market leader and industry standard, used by artists including Michael Jackson, Madonna, and John Carpenter. In the 1980s, Sequential was pivotal in the development of MIDI, a technical standard for synchronizing electronic instruments. In 1987, Sequential went out of business and was purchased by Yamaha. Smith continued to develop instruments through a new company, Dave Smith Instruments. In 2015, Yamaha returned the Sequential Circuits trademark to Dave Smith Instruments, which rebranded as Sequential in 2018. In 2021, Sequential was acquired by the British audio technology company Focusrite. History 1974–1980: Founding, first products and Prophet-5 The engineer Dave Smith founded Sequential Circuits in San Francisco in 1974. The first Sequential Circuits product wa ...

Sequential Circuits Six-Trak
The Six-Trak was an analogue synthesizer manufactured by Sequential Circuits in San Jose, California and released in January 1984. It is notable for being one of the first multi-timbral synthesizers, equipped with MIDI and an on-board six-track digital sequencer, hence the name. It was designed as an inexpensive and easily portable 'scratch-pad' machine for trying out arrangements. You can latch the arpeggiator and play along with sequences in real time. Also available is a unison mode which renders the keyboard monophonic but allows for very rich sounding timbres. The Six-Trak is prominently featured and can be heard on the 1998 minimalist space music CD release ''The Dream Garden'', by musician/composer Dane Rochelle. More recently it has been used by composeChristopher de Grootfor the 2012 soundtrack to Australian feature film "Sororal". The Six-Trak's more famous sibling is the Prophet 5, widely used in much of the 1970s progressive rock. A number of other synthesizers ma ...

Semitone
A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale. For example, C is adjacent to C; the interval between them is a semitone. In a 12-note approximately equally divided scale, any interval can be defined in terms of an appropriate number of semitones (e.g. a whole tone or major second is 2 semitones wide, a major third 4 semitones, and a perfect fifth 7 semitones. In music theory, a distinction is made between a diatonic semitone, or minor second (an interval encompassing two different staff positions, e.g. from C to D) and a chromatic semitone or augmented unison (an interval between two notes at the same staff position, e.g. from C to C). These are enharmonically equivalent when twelve-tone equal temperament is used, but are not the same thing in meantone temper ...

Aftertouch
Keyboard expression is the ability of a keyboard instrument, keyboard musical instrument to change tone or other qualities of the sound in response to velocity, pressure or other variations in how the performer depresses the keys of the musical keyboard. Expression types include: * ''Velocity sensitivity''—how fast the key is pressed * ''Aftertouch'', or ''pressure sensitivity'' — the amount of pressure on a key, once already held down * ''Displacement sensitivity''—distance that a key is pressed down Keyboard instruments offer a range of expression types. Acoustic pianos, such as upright and grand pianos, are velocity-sensitive—the faster the key strike, the harder the hammer hits the strings. Baroque-style clavichords and professional synthesizers are aftertouch-sensitive—applied force on the key after the initial strike produces effects such as vibrato or swells in loudness, volume. Tracker pipe organs and some electronic organs are displacement-sensitive—partly dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltage-controlled Oscillator
A microwave (12–18GHz) voltage-controlled oscillator A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by applying a modulating signal to the control input. A VCO is also an integral part of a phase-locked loop. VCOs are used in synthesizers to generate a waveform whose pitch can be adjusted by a voltage determined by a musical keyboard or other input. A voltage-to-frequency converter (VFC) is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages. Types VCOs can be generally categorized into two groups based on the type of waveform produced. * ''Linear'' or '' harmonic oscillators'' generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waveforms
In electronics, acoustics, and related fields, the waveform of a signal is the shape of its graph as a function of time, independent of its time and magnitude scales and of any displacement in time.David Crecraft, David Gorham, ''Electronics'', 2nd ed., , CRC Press, 2002, p. 62 In electronics, the term is usually applied to periodically varying voltages, currents, or electromagnetic fields. In acoustics, it is usually applied to steady periodic sounds—variations of pressure in air or other media. In these cases, the waveform is an attribute that is independent of the frequency, amplitude, or phase shift of the signal. The term can also be used for non-periodic signals, like chirps and pulses. The waveform of an electrical signal can be visualized in an oscilloscope or any other device that can capture and plot its value at various times, with a suitable scales in the time and value axes. The electrocardiograph is a medical device to record the waveform of the electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 hear ...

Voltage-controlled Filter
A voltage-controlled filter (VCF) is an electronic filter whose operating characteristics (primarily cutoff frequency) can be set by an input control voltage. Voltage controlled filters are widely used in synthesizers. A music synthesizer VCF allows its cutoff frequency, and sometimes its Q factor (resonance at the cutoff frequency), to be continuously varied. The filter outputs often include a lowpass response, and sometimes highpass, bandpass or notch responses. Some musical VCFs offer a variable ''slope'' which determines the rate of attenuation outside the bandpass, often at 6 dB/octave, 12 dB/octave, 18 dB/octave or 24 dB/octave (one-, two-, three- and four-pole filters, respectively). In modular analog synthesizers, VCFs receive signal input from signal sources, including oscillators and noise, or the output of other processors. By varying the cutoff frequency, the filter passes or attenuates partials of the input signal. In some popular electroni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuse (electrical)
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type. Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity, and response times, depending on the application. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. Short circuits, overloading, mismatched loads, or device failure are the prime ...
