Problem: A synthesizer (often abbreviated as synth, also spelled synthesiser) is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate traditional musical instruments like piano, Hammond organ, flute, vocals; natural sounds like ocean waves, etc.; or generate novel electronic timbres. They are often played with a musical keyboard, but they can be controlled via a variety of other input devices, including music sequencers, instrument controllers, fingerboards, guitar synthesizers, wind controllers, and electronic drums. Synthesizers without built-in controllers are often called sound modules, and are controlled via USB, MIDI or CV/gate using a controller device, often a MIDI keyboard or other controller.

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.

Problem: Willie Nelson was born in Abbott, Texas on April 29, 1933, during the Great Depression, to Myrle Marie (nee Greenhaw) and Ira Doyle Nelson. He was born on April 29, but his birth was recorded by doctor F. D. Sims on April 30. He was named Willie by his cousin Mildred, who also chose Hugh as his middle name, in honor of her recently deceased younger brother. His parents moved from Arkansas in 1929, to look for work.

Nelson has been arrested several times for marijuana possession. The first occasion was in 1974 in Dallas, Texas. In 1977 after a tour with Hank Cochran, Nelson traveled to The Bahamas. Nelson and Cochran arrived late to the airport and boarded the flight without luggage. The bags were later sent to them. As Nelson and Cochran claimed their luggage in the Bahamas, a customs officer questioned Nelson after marijuana was found in a pair of his jeans. Nelson was arrested and jailed. As Cochran made arrangements to pay the bail, he took Nelson a six-pack of beer to his cell. Nelson was released a few hours later. Inebriated, he fell after he jumped celebrating and was taken to the emergency room. He then appeared before the judge, who dropped the charges but ordered Nelson to never return to the country. In 1994, highway patrolmen found marijuana in his car near Waco, Texas. His requirement to appear in court prevented him attending the Grammy awards that year. While traveling to Ann W. Richards' funeral in 2006, Nelson, along with his manager and his sister, Bobbie, were arrested in St. Martin Parish, Louisiana and charged with possession of marijuana and hallucinogenic mushrooms. Nelson received six months probation. On November 26, 2010, Nelson was arrested in Sierra Blanca, Texas, for possession of six ounces of marijuana found in his tour bus while traveling from Los Angeles back to Texas. He was released after paying bail of US$2,500. Prosecutor Kit Bramblett supported not sentencing Nelson to jail due to the small amount of marijuana involved, but suggested instead a US$100 fine and told Nelson that he would have him sing "Blue Eyes Crying in the Rain" for the court. Judge Becky Dean-Walker said that Nelson would have to pay the fine but not to perform the song, explaining that the prosecutor was joking. Nelson's lawyer Joe Turner reached an agreement with the prosecutor. Nelson was set to pay a US$500 fine to avoid a two-year jail sentence with a 30-day review period, which in case of another incident would end the agreement. The judge later rejected the agreement, claiming that Nelson was receiving preferential treatment for his celebrity status; the offense normally carried a one-year jail sentence. Bramblett declared that the case would remain open until it was either dismissed or the judge changed her opinion.
