input: A ribbon controller or other violin-like user interface may be used to control synthesizer parameters. The idea dates to Leon Theremin's 1922 first concept and his 1932 Fingerboard Theremin and Keyboard Theremin, Maurice Martenot's 1928 Ondes Martenot (sliding a metal ring), Friedrich Trautwein's 1929 Trautonium (finger pressure), and was also later utilized by Robert Moog. The ribbon controller has no moving parts. Instead, a finger pressed down and moved along it creates an electrical contact at some point along a pair of thin, flexible longitudinal strips whose electric potential varies from one end to the other. Older fingerboards used a long wire pressed to a resistive plate. A ribbon controller is similar to a touchpad, but a ribbon controller only registers linear motion. Although it may be used to operate any parameter that is affected by control voltages, a ribbon controller is most commonly associated with pitch bending. Fingerboard-controlled instruments include the Trautonium (1929), Hellertion (1929) and Heliophon (1936), Electro-Theremin (Tannerin, late 1950s), Persephone (2004), and the Swarmatron (2004). A ribbon controller is used as an additional controller in the Yamaha CS-80 and CS-60, the Korg Prophecy and Korg Trinity series, the Kurzweil synthesizers, Moog synthesizers, and others. Rock musician Keith Emerson used it with the Moog modular synthesizer from 1970 onward. In the late 1980s, keyboards in the synth lab at Berklee College of Music were equipped with membrane thin ribbon style controllers that output MIDI. They functioned as MIDI managers, with their programming language printed on their surface, and as expression/performance tools. Designed by Jeff Tripp of Perfect Fretworks Co., they were known as Tripp Strips. Such ribbon controllers can serve as a main MIDI controller instead of a keyboard, as with the Continuum instrument.

input: NBC kept Letterman under contract to try him in a different time slot. Late Night with David Letterman debuted February 1, 1982; the first guest on the first show was Bill Murray. Murray later went on to become one of Letterman's most recurrent guests, guesting on the show's 30th anniversary episode, which aired January 31, 2012 and on the very last show, which aired May 20, 2015. The show ran Monday through Thursday at 12:30 a.m. Eastern Time, immediately following The Tonight Show Starring Johnny Carson (a Friday night broadcast was added in June 1987). It was seen as being edgy and unpredictable, and soon developed a cult following (particularly among college students). Letterman's reputation as an acerbic interviewer was borne out in verbal sparring matches with Cher (who even called him an asshole on the show), Shirley MacLaine, Charles Grodin, and Madonna. The show also featured comedy segments and running characters, in a style heavily influenced by the 1950s and 1960s programs of Steve Allen. The show often featured quirky, genre-mocking regular features, including "Stupid Pet Tricks" (which had its origins on Letterman's morning show), Stupid Human Tricks, dropping various objects off the roof of a five-story building, demonstrations of unorthodox clothing (such as suits made of Alka-Seltzer, Velcro and suet), a recurring Top 10 list, the Monkey-Cam (and the Audience Cam), a facetious letter-answering segment, several "Film[s] by My Dog Bob" in which a camera was mounted on Letterman's own dog (often with comic results) and Small Town News, all of which would eventually move with Letterman to CBS. Other memorable moments included Letterman using a bullhorn to interrupt a live interview on The Today Show, announcing that he was the NBC News president and that he was not wearing any pants; walking across the hall to Studio 6B, at the time the news studio for WNBC-TV, and interrupting Al Roker's weather segments during Live at Five; and staging "elevator races", complete with commentary by NBC Sports' Bob Costas. In one infamous appearance, in 1982, Andy Kaufman (who was already wearing a neck brace) appeared with professional wrestler Jerry Lawler, who slapped and knocked the comedian to the ground (though Lawler and Kaufman's friend Bob Zmuda later revealed that the event was staged).

input: In March 1992, Black sued his manager, Bill Ham, for breach of contract; Black sought $2 million in damages and requested that Ham return $4 million in royalties. Under the terms of their initial contract, Ham controlled all publishing royalties for any song that Black wrote or co-wrote for his first eight albums. Because Black wrote all of his own music, this amounted to a fee of 20 to 30 cents per album sold. Industry standards generally counseled songwriters to form their own publication companies, so they would be able to retain more of the royalties. Ham promptly countersued, blaming the initial lawsuit on poor advice Black received from his new personal assistant, his mother-in-law Jonni Hartman. His lawyer told the press that "Mr. Ham invested $1 million of his own money in Clint Black's career at a time when nobody else would do so. For that commitment, Mr. Black should show a little gratitude and honor his contracts". By mid-1992, Black's first two albums had sold a combined 5 million copies. The difficulties with Ham caused a delay in the release of Black's third album, The Hard Way, which was released on July 14. The album had been expected the year previously, and during the delay the country music scene changed. Both Alan Jackson and Travis Tritt achieved greater success, and Billy Ray Cyrus became a teen idol. The competition that Black faced was now much stiffer than with his earlier albums. According to Black, he and producer James Stroud spent more time putting this album together than either of those preceding and were "a lot more aggressive in the way we cut and mixed the album". Black was also more satisfied with the vocals on this album. Several of the songs on The Hard Way, including "Burn One Down", were initially reported to be Black's responses to his situation with Ham. Co writer Nicholas refuted the rumors, maintaining that most of those songs were written in the late 1980s. To promote the album, Black launched The Hard Way Tour on June 26, 1992. The tour ran for 11 months. Reviewers noticed that with this album Black presented a "new, sexier image", wearing tighter clothing and in many cases leaving behind his trademark hat. Black commented simply that he was bored wearing the hat all the time.
