LM-1

In 1980, Roger Linn released the world's first drum machine to use digital samples, the LM-1 Drum Computer.^[7] The LM-1 was the first drum machine to use samples of a real drum kit, which Linn recorded with Los Angeles session drummer Art Wood.^[8] Examples of the LM-1 in use can be found on recordings by Prince, Gary Numan, and Michael Jackson.^[9]

LinnDrum

In 1982 Linn released the LinnDrum as the successor to the LM-1. It improved on the LM-1 in some ways like the addition of crash and ride cymbal samples. One drawback: on the LinnDrum, only the snare, tom, and conga samples can be tuned, whereas the LM-1 allows every sound to be individually tuned. Its high-quality samples, flexibility and affordability made the LinnDrum popular. It sold more units than its predecessor (the LM-1) and its successor (the Linn 9000) combined. The LinnDrum was used on countless recordings throughout the 1980s, including a-Ha's international hit "Take On Me".

Linn 9000

In 1984 Linn released the Linn 9000 as the successor to the LinnDrum. It was the first integrated digital drum machine and MIDI sequencer. The 9000 had innovative features, like dynamic sensitive rubber pads,^[10] and would influence many future drum machine designs.^[11] But chronic software bugs^[12][13] led to a reputation for unreliability and contributed to the eventual demise of the company.^[14][15] The 9000 can be heard on Michael Jackson's 1987 album, Bad, on the cuts such as "Bad" and "Liberian Girl".

LinnSequencer

In 1985, Linn released the LinnSequencer, a rack mount 32 track hardware MIDI sequencer. It used the same flawed operating system used in the Linn 9000.^[16] As a result, the machine earned a reputation for unreliability.^[12][13]

LinnDrum Midistudio

In January 1986, Linn debuted the LinnDrum Midistudio at the NAMM Winter Music & Sound Market as the successor to the Linn 9000. The Midistudio is essentially a rack mount version of the Linn 9000 with some improvements.^[17] It used the same flawed operating system used in the Linn 9000.^[18] It never went into production because Linn Electronics went out of business the following month.^[19]

Similarities between the LinnDrum Midistudio and the Akai MPC series lead some to perceive a family resemblance.^[20][21][22] Most notably, the Midistudio has sixteen dynamic sensitive rubber pads in the distinctive, four by four pattern, that would become the hallmark of the MPCs, starting with the MPC60.

Legacy

Linn Electronics went out of business in February 1986. Forat Electronics purchased their remaining assets,^[23] manufactured and sold the Forat F9000 and LinnSequencer until 1994 and provide service, sounds, customization and upgrades for the entire Linn Electronics line.

The LM-1, LinnDrum and Linn 9000 became synonymous with the music of the 1980s. The Linn 9000 and LinnDrum Midistudio pioneered the concept of the Music Production Center or MPC.

AdrenaLinn

The AdrenaLinn is a digital multi-effects unit with a drum machine and amp modeler all in one, designed by Roger Linn with some help from Dave Smith (credited with helping to conceive MIDI) and Tom Oberheim (designer of early analog synthesizers). Most notably, unlike other guitar pedals, the AdrenaLinn specializes in beat-synced effects, including modulation and delay but also a sequencer that provides looped patterns of filtered tones, all moving in sync to its internal drum machine or to midi. The drum section can also be affected by the filter section, allowing dance-style beats. Other unusual aspects of this pedal include note-triggered filter effects such as auto-wah, simulated talk box and guitar synthesizer sounds. The AdrenaLinn technology was also the basis of Roger Linn's partnership with M-Audio to create the Black Box guitar multi-effect and recording unit.^[1]

The AdrenaLinn can be heard on the following records (among many others):

• John Mayer – "Heartbreak Warfare", from the 2009 album Battle Studies, "Bigger Than My Body" from the 2003 album Heavier Things and "I Don't Trust Myself (With Loving You)" from the 2006 album Continuum
• Green Day – "Boulevard of Broken Dreams" from the 2004 album American Idiot
• Red Hot Chili Peppers – By The Way – Warner Bros. – 2002 (produced by Rick Rubin)
• Morcheeba – Parts Of The Process – Reprise Records – 2003
• Marillion – Marbles – 2004^[29]

The AdrenaLinn was followed-up with the AdrenaLinn II and AdrenaLinn III.

LinnDrum II

Roger Linn and Dave Smith announced co-development of a drum machine product, originally to be called BoomChik, but changed to LinnDrum II in December 2007, a reference to one of Linn's early popular drum machines: the LinnDrum. The LinnDrum II was renamed the Tempest, and co-released by Roger Linn Designs and Dave Smith Instruments in 2011.

LinnStrument

In late 2014, after several years of development, Linn released the LinnStrument, a music performance controller with 3D note expression. The grid based MIDI controller, playable with one or two hands, is velocity sensitive, but also senses three dimensions per finger, polyphonically. It can employ MPE, thereby using a full MIDI channel per note. Two versions are available, the larger original LinnStrument as well as the smaller LinnStrument 128.^[30]

Almost the entire surface of the controller is covered by its 8 by 25 (or 8 by 16 in the case of the LinnStrument 128) grid. The fingertip-sized fields are each able to measure and transmit velocity, aftertouch, x-position relative to the entire row (or any subset thereof), y-position within a field, as well as release velocity.^[31] It is highly adaptable and can also function in more traditional MIDI configurations, accommodating sound generators that don't yet support MPE and allowing them to be played more expressively.

The LinnStrument has several additional features, such as an arpeggiator, a velocity-sensitive step sequencer as well as freely assignable virtual MIDI faders. It is USB-powered and can communicate via USB or 5-pin MIDI.
