82-601: The Atari Mega STE is Atari Corporation 's final Motorola 68000 -based personal computer in the Atari ST series and the second to last model overall. Released in 1991, the Mega STE is a late-model STE mounted in the case of an Atari TT computer. It was followed by the higher end Atari Falcon in 1992. The MEGA STE is based on STE hardware. The 2 MB and 4 MB models shipped with a high-resolution mono monitor, and an internal SCSI hard disk (the 1 MB model includes neither
164-779: A Resource Interchange File Format (RIFF) wrapper, as RMID files with a .rmi extension. RIFF-RMID has been deprecated in favor of Extensible Music Files ( XMF ). The main advantage of the personal computer in a MIDI system is that it can serve a number of different purposes, depending on the software that is loaded. Multitasking allows simultaneous operation of programs that may be able to share data with each other. Sequencing software allows recorded MIDI data to be manipulated using standard computer editing features such as cut, copy and paste and drag and drop . Keyboard shortcuts can be used to streamline workflow, and, in some systems, editing functions may be invoked by MIDI events. The sequencer allows each channel to be set to play
246-413: A daisy-chain arrangement. Not all devices feature thru ports, and devices that lack the ability to generate MIDI data, such as effects units and sound modules, may not include out ports. Each device in a daisy chain adds delay to the system. This can be avoided by using a MIDI thru box, which contains several outputs that provide an exact copy of the box's input signal. A MIDI merger is able to combine
328-456: A sequencer or digital audio workstation to be edited or played back. MIDI also defines a file format that stores and exchanges the data. Advantages of MIDI include small file size , ease of modification and manipulation and a wide choice of electronic instruments and synthesizer or digitally sampled sounds . A MIDI recording of a performance on a keyboard could sound like a piano or other keyboard instrument; however, since MIDI records
410-403: A technical standard that describes a communication 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. 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
492-536: A 1.44 MB HD floppy support. Support for a third/middle mouse button is also included. A unique feature of the MEGA STE in relation to previous Atari systems is the software-switchable CPU speed, which allows the CPU to operate at 16 MHz for faster processing or 8 MHz for better compatibility with old software. An upgrade to the operating system was also produced after the first units were shipped that upgraded
574-423: A 2 MB of wavetable storage, a space too small in which to fit good-quality samples of 128 General MIDI instruments plus drum kits. To make the most of the limited space, some manufacturers stored 12-bit samples and expanded those to 16 bits on playback. Despite its association with music devices, MIDI can control any electronic or digital device that can read and process a MIDI command. MIDI has been adopted as
656-588: A Roland keyboard into a Yamaha synthesizer module. With MIDI, any MIDI-compatible keyboard (or other controller device) can be connected to any other MIDI-compatible sequencer, sound module, drum machine , synthesizer, or computer, even if they are made by different manufacturers. MIDI technology was standardized in 1983 by a panel of music industry representatives, and is maintained by the MIDI Manufacturers Association (MMA). All official MIDI standards are jointly developed and published by
738-452: A computer. In this way the device's limited patch storage is augmented by a computer's much greater disk capacity. Once transferred to the computer, it is possible to share custom patches with other owners of the same instrument. Universal editor/librarians that combine the two functions were once common, and included Opcode Systems' Galaxy, eMagic 's SoundDiver, and MOTU's Unisyn. Although these older programs have been largely abandoned with
820-427: A control protocol in a number of non-musical applications. MIDI Show Control uses MIDI commands to direct stage lighting systems and to trigger cued events in theatrical productions. VJs and turntablists use it to cue clips, and to synchronize equipment, and recording systems use it for synchronization and automation . Wayne Lytle, the founder of Animusic , derived a system he dubbed MIDIMotion in order to produce
902-479: A different sound and gives a graphical overview of the arrangement. A variety of editing tools are made available, including a notation display or scorewriter that can be used to create printed parts for musicians. Tools such as looping , quantization , randomization, and transposition simplify the arranging process. Beat creation is simplified, and groove templates can be used to duplicate another track's rhythmic feel. Realistic expression can be added through
SECTION 10
#1732773152188984-496: A full-band arrangement in a style that the user selects, and send the result to a MIDI sound generating device for playback. The generated tracks can be used as educational or practice tools, as accompaniment for live performances, or as a songwriting aid. Computers can use software to generate sounds, which are then passed through a digital-to-analog converter (DAC) to a power amplifier and loudspeaker system. The number of sounds that can be played simultaneously (the polyphony )
1066-481: A home environment, an artist can reduce recording costs by arriving at a recording studio with a partially completed song. In 2022, the Guardian wrote that MIDI remained as important to music as USB was to computing, and represented "a crucial value system of cooperation and mutual benefit, one all but thrown out by today's major tech companies in favour of captive markets". As of 2022, Smith's original MIDI design
1148-466: 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 the audience hears produced by a keyboard amplifier . MIDI data can be transferred via MIDI or USB cable, or recorded to
1230-507: A low latency through tight driver integration, and therefore could run only on Creative Labs soundcards. Syntauri Corporation's Alpha Syntauri was another early software-based synthesizer. It ran on the Apple IIe computer and used a combination of software and the computer's hardware to produce additive synthesis. Some systems use dedicated hardware to reduce the load on the host CPU, as with Symbolic Sound Corporation 's Kyma System, and
1312-513: A monitor, hard disk nor hard disk controller). While offering better ST compatibility than the TT, it also includes a number of TT features, from the ST-grey version of the TT case with a separate keyboard and system unit, optional FPU , a VMEbus slot, two extra RS232 ports (all 9-pin rather than 25-pin as previous models had), a LocalTalk / RS-422 port (no AppleTalk software was ever produced) and
1394-562: A more expandable PC-2 model at a higher price point, this being announced alongside the PC-3 in November 1987. Responding to the introduction of the low-cost Amstrad PC1512 in the UK, price points for the initial PC model were given as around £400 including VAT for a 512 KB floppy-only model supporting CGA, EGA and Hercules graphics, rising to £1000 including VAT for a hard drive model. Later,
1476-650: A note is played on a MIDI instrument, it generates a digital MIDI message that can be used to trigger a note on another instrument. The capability for remote control allows full-sized instruments to be replaced with smaller sound modules, and allows musicians to combine instruments to achieve a fuller sound, or to create combinations of synthesized instrument sounds, such as acoustic piano and strings. MIDI also enables other instrument parameters (volume, effects, etc.) to be controlled remotely. Synthesizers and samplers contain various tools for shaping an electronic or digital sound. Filters adjust timbre , and envelopes automate
1558-620: A role in mainstream music production. In the years immediately after the 1983 ratification of the MIDI specification, MIDI features were adapted to several early computer platforms. The Yamaha CX5M introduced MIDI support and sequencing in an MSX system in 1984. The spread of MIDI on home computers was largely facilitated by Roland Corporation 's MPU-401 , released in 1984, as the first MIDI-equipped sound card , capable of MIDI sound processing and sequencing. After Roland sold MPU sound chips to other sound card manufacturers, it established
1640-524: A simpler, cheaper alternative. While Smith discussed the concept with American companies, Kakehashi discussed it with Japanese companies Yamaha , Korg and Kawai . Representatives from all companies met to discuss the idea in October. Initially, only Sequential Circuits and the Japanese companies were interested. Using Roland's DCB as a basis, Smith and Sequential Circuits engineer Chet Wood devised
1722-447: A small LCD. Digital instruments typically discourage users from experimentation, due to their lack of the feedback and direct control that switches and knobs would provide, but patch editors give owners of hardware instruments and effects devices the same editing functionality that is available to users of software synthesizers. Some editors are designed for a specific instrument or effects device, while other, universal editors support
SECTION 20
#17327731521881804-539: A universal interface to allow communication between equipment from different manufacturers. Smith and Wood proposed this standard in a paper, Universal Synthesizer Interface, at the Audio Engineering Society show in October 1981. The standard was discussed and modified by representatives of Roland, Yamaha, Korg, Kawai, and Sequential Circuits. Kakehashi favored the name Universal Musical Interface (UMI), pronounced you-me , but Smith felt this
1886-465: A universal standard MIDI-to-PC interface. The widespread adoption of MIDI led to computer-based MIDI software being developed. Soon after, a number of platforms began supporting MIDI, including the Apple II , Macintosh , Commodore 64 , Amiga , Acorn Archimedes , and IBM PC compatibles . The 1985 Atari ST shipped with MIDI ports as part of the base system. In 2015, Retro Innovations released
1968-516: A user with no notation skills to build complex arrangements. A musical act with as few as one or two members, each operating multiple MIDI-enabled devices, can deliver a performance similar to that of a larger group of musicians. The expense of hiring outside musicians for a project can be reduced or eliminated, and complex productions can be realized on a system as small as a synthesizer with integrated keyboard and sequencer. MIDI also helped establish home recording . By performing preproduction in

System Exclusive messages use the MIDI protocol to send information about the synthesizer's parameters. Patch librarians have the specialized function of organizing the sounds in a collection of equipment and exchanging entire banks of sounds between an instrument and
2132-584: Is available that can print scores in braille . Notation programs include Finale , Encore , Sibelius , MuseScore and Dorico . SmartScore software can produce MIDI files from scanned sheet music. Patch editors allow users to program their equipment through the computer interface. These became essential with the appearance of complex synthesizers such as the Yamaha FS1R , which contained several thousand programmable parameters, but had an interface that consisted of fifteen tiny buttons, four knobs and
2214-500: Is dependent on the power of the computer's CPU , as are the sample rate and bit depth of playback, which directly affect the quality of the sound. Synthesizers implemented in software are subject to timing issues that are not necessarily present with hardware instruments, whose dedicated operating systems are not subject to interruption from background tasks as desktop operating systems are. These timing issues can cause synchronization problems, and clicks and pops when sample playback
2296-476: Is interrupted. Software synthesizers also may exhibit additional latency in their sound generation. The roots of software synthesis go back as far as the 1950s, when Max Mathews of Bell Labs wrote the MUSIC-N programming language, which was capable of non-real-time sound generation. Reality, by Dave Smith's Seer Systems was an early synthesizer that ran directly on a host computer's CPU. Reality achieved
2378-591: Is possible to change the key, instrumentation or tempo of a MIDI arrangement, and to reorder its individual sections, or even edit individual notes. The ability to compose ideas and quickly hear them played back enables composers to experiment. Algorithmic composition programs provide computer-generated performances that can be used as song ideas or accompaniment. Some composers may take advantage of standard, portable set of commands and parameters in MIDI 1.0 and General MIDI (GM) to share musical data files among various electronic instruments. The data composed via
2460-515: Is serial, it can only send one event at a time. If an event is sent on two channels at once, the event on the second channel cannot transmit until the first one is finished, and so is delayed by 1 ms. If an event is sent on all channels at the same time, the last channel's transmission is delayed by as much as 16 ms. This contributed to the rise of MIDI interfaces with multiple in- and out-ports, because timing improves when events are spread between multiple ports as opposed to multiple channels on
2542-490: Is used to trigger dialogue, sound effect, and music cues in stage and broadcast production. With MIDI, notes played on a keyboard can automatically be transcribed to sheet music . Scorewriting software typically lacks advanced sequencing tools, and is optimized for the creation of a neat, professional printout designed for live instrumentalists. These programs provide support for dynamics and expression markings, chord and lyric display, and complex score styles. Software

The low-fidelity reproduction of these ubiquitous cards was often assumed to somehow be a property of MIDI itself. This created a perception of MIDI as low-quality audio, while in reality MIDI itself contains no sound, and

Then in 1986, Atari Corp. launched two consoles designed when Atari was under Warner's control: Atari 2600 Jr and Atari 7800 (which had a limited release in 1984). Atari Corp. rebounded, producing a $ 25 million profit for 1986. The Atari ST line proved very successful (mostly in Europe, not

The ability to construct full MIDI arrangements entirely in computer software allows a composer to render a finalized result directly as an audio file. Early PC games were distributed on floppy disks, and the small size of MIDI files made them a viable means of providing soundtracks. Games of

These cards used FM synthesis , which generates sound through modulation of sine waves . John Chowning , the technique's pioneer, theorized that the technology would be capable of accurate recreation of any sound if enough sine waves were used , but budget computer audio cards performed FM synthesis with only two sine waves. Combined with

In the final quarter of 1987, Federated lost $ 6.4 million in day-to-day operations. A post-acquisition audit ended on February 15, 1988, and identified $ 43 million in adjustments to Federated's balance sheet, far more than Atari anticipated. The net worth of its acquisition

However, a shortage of parts kept the system from being released nationwide for the 1989 Christmas season; the Lynx lost market share to Nintendo 's Game Boy , which had only a monochrome display, but a much better battery life, and was widely available. As the fortunes of Atari's computers faded, video games again became

On March 13, 1998, JTS Corporation sold the Atari name and assets to Hasbro Interactive for $ 5 million, less than a fifth of what Warner Communications had paid 22 years earlier. The transaction primarily involved the brand and intellectual property rights, which Hasbro Interactive largely used as a brand name for retro game releases. On January 29, 2001, Hasbro Interactive

In addition, the Tramiel family wanted out of the business. On February 13, 1996, Atari agreed to merge with JTS Inc. , a short-lived maker of hard disk drives, in a reverse takeover to form JTS Corporation . The reverse merger
3526-513: The MIDI Manufacturers' Association standardized the wiring. The MIDI-over-minijack standards document also recommends the use of 2.5 mm connectors over 3.5 mm ones to avoid confusion with audio connectors. Most devices do not copy messages from their input to their output port. A third type of port, the thru port, emits a copy of everything received at the input port, allowing data to be forwarded to another instrument in

Some computer sound cards include a standard MIDI connector, whereas others connect by any of various means that include the D-subminiature DA-15 game port , USB , FireWire , Ethernet or a proprietary connection. The increasing use of USB connectors in the 2000s has led to the availability of MIDI-to-USB data interfaces that can transfer MIDI channels to USB-equipped computers. Some MIDI keyboard controllers are equipped with USB jacks, and can be connected directly to computers that run music software. MIDI's serial transmission leads to timing problems. A three-byte MIDI message requires nearly 1 millisecond for transmission. Because MIDI

In 2016, the MMA established The MIDI Association (TMA) to support a global community of people who work, play, or create with MIDI. In the early 1980s, there was no standardized means of synchronizing electronic musical instruments manufactured by different companies. Manufacturers had their own proprietary standards to synchronize instruments, such as CV/gate , DIN sync and Digital Control Bus (DCB). Ikutaro Kakehashi ,

Rather, it is a set of instructions – for example, for pitch or tempo – and can use a thousand times less disk space than the equivalent recorded audio. Due to their tiny filesize, fan-made MIDI arrangements became an attractive way to share music online, before

Still, after initially outselling the Amiga line, its closest competitor in the marketplace, the Amiga outsold it 3 to 2 in the end. Atari eventually released a line of inexpensive IBM PC compatibles , announcing a budget model at "a record-breaking price of under $ 599" in early 1987, to be followed by
3936-449: The advent of broadband internet access and multi-gigabyte hard drives. The major drawback to this is the wide variation in quality of users' audio cards, and in the actual audio contained as samples or synthesized sound in the card that the MIDI data only refers to symbolically. Even a sound card that contains high-quality sampled sounds can have inconsistent quality from one sampled instrument to another. Early budget-priced cards, such as

Wavetable daughterboards that were later available provided audio samples that could be used in place of the FM sound. These were expensive, but often used the sounds from respected MIDI instruments such as the E-mu Proteus . The computer industry moved in the mid-1990s toward wavetable-based soundcards with 16-bit playback, but standardized on

One of the first entries in the fifth generation of game consoles , the Jaguar was marketed as the world's first 64-bit console. However, due to a games library which was low in both quantity and quality, as well as being extremely difficult to program games for the system because of its multi-chip architecture, it

The Standard MIDI File ( SMF ) is a file format that provides a standardized way for music sequences to be saved, transported, and opened in other systems. The standard was developed and is maintained by the MMA, and usually uses a .mid extension. The compact size of these files led to their widespread use in computers, mobile phone ringtones , webpage authoring and musical greeting cards. These files are intended for universal use and include such information as note values, timing and track names. Lyrics may be included as metadata , and can be displayed by karaoke machines. SMFs are created as an export format of software sequencers or hardware workstations. They organize MIDI messages into one or more parallel tracks and time-stamp

These tools allow composers to audition and edit their work much more quickly and efficiently than did older solutions, such as multitrack recording . Compositions can be programmed for MIDI that are impossible for human performers to play. Because a MIDI performance is a sequence of commands that create sound, MIDI recordings can be manipulated in ways that audio recordings cannot. It

6068-477: Was formed to continue overseeing the standard. In 2017, an abridged version of MIDI 1.0 was published as international standard IEC 63035. An initiative to create a 2.0 standard was announced in January 2019. The MIDI 2.0 standard was introduced at the 2020 Winter NAMM Show. The BBC cited MIDI as an early example of open-source technology. Smith believed MIDI could only succeed if every manufacturer adopted it, and so "we had to give it away". MIDI's appeal
6150-441: Was originally limited to professional musicians and record producers who wanted to use electronic instruments in the production of popular music . The standard allowed different instruments to communicate with each other and with computers, and this spurred a rapid expansion of the sales and production of electronic instruments and music software. This interoperability allowed one device to be controlled from another, which reduced
6232-725: Was published in August 1983. The MIDI standard was unveiled by Kakehashi and Smith, who received Technical Grammy Awards in 2013 for their work. In 1983, the first instruments were released with MIDI, the Roland Jupiter-6 and the Prophet 600. In 1983, the first MIDI drum machine , the Roland TR-909 , and the first MIDI sequencer , the Roland MSQ-700, were released. The MIDI Manufacturers Association (MMA)
6314-585: Was purportedly to offset the unanticipated losses in the purchase of Federated. In March 1989, Atari announced that it would treat Federated as a discontinued operation and took an additional one-time charge of $ 57 million. Federated was eventually sold to Silo in 1989. In 1988, Stewart Alsop II said that Atari was among several companies that "have already been knocked out" of the GUI market by Apple , IBM / Microsoft , and others, but Atari's sales hit their peak that year, at $ 452 million. In 1989, Atari released
6396-591: Was reduced by $ 33 million. Atari's CFO later claimed that they would never have done the deal had they known at the time. Federated's operational losses increased, reaching $ 67 million for its first full year under Atari in 1988. The FBI began an investigation of Atari in May of that same year for an ongoing scheme involving the profitable import and resale of Japanese DRAM chips in the US, "in violation of U.S. import laws and contrary to import agreements." This alleged DRAM scheme
6478-468: Was sold to Infogrames , which renamed it Infogrames Interactive and then the Atari Interactive name in 2003. The present day Atari Interactive , through Atari SA, continues to hold and license all Atari trademarks as well as produce many new games, some based on Atari's original properties, to this day. MIDI MIDI ( / ˈ m ɪ d i / ; Musical Instrument Digital Interface ) is
6560-451: Was still in use. MIDI was invented so that electronic or digital musical instruments could communicate with each other and so that one instrument can control another. For example, a MIDI-compatible sequencer can trigger beats produced by a drum sound module . Analog synthesizers that have no digital component and were built prior to MIDI's development can be retrofitted with kits that convert MIDI messages into analog control voltages. When
6642-512: Was to design and sell a next-generation home computer. On July 1, 1984, TTL bought the Consumer Division assets of Atari, Inc. from Warner, and TTL was renamed Atari Corporation. Warner sold the division in exchange for $ 240 million in stock in the new company. Under Tramiel's ownership, Atari used the remaining stock of game console inventory to keep the company afloat while they finished the development of their 16-bit computer system,
6724-538: Was unable to compete effectively against the incumbent fourth generation consoles ; the Sega Saturn and Sony PlayStation would outsell the Jaguar in very large numbers late in its lifespan. Atari sustained a net loss of $ 49.6 million for 1995, with $ 27.7 million in losses during the last quarter of the year alone. In December 1995, Sam Tramiel suffered a mild heart attack, forcing him to step down as Atari's president, causing Jack Tramiel to come back and lead
