The Korg M1 is a synthesizer and music workstation manufactured by Korg from 1988 to 1995. It is one of the bestselling synthesizers in history, selling an estimated 250,000 units. The M1 was widely used in popular music and stock music in the late 80s and early 90s. The piano and organ presets were used in 1990s house music, beginning with Madonna's 1990 single "Vogue".
Development
Korg's chief engineer, Junichi Ikeuchi, led the hardware engineering design of the M1.[4] Whereas previous synthesizers had shipped with sounds chosen for different markets, the Korg chairman, Tsutomu Kato, and his son Seiki decided that their synthesizers should use the same sounds internationally. Korg assembled an international team to develop the sounds for the M1. To create a deep blown bottle sound, the team played a pan flute over a large sake bottle.[5]
Features
The M1 features a 61-note velocity- and aftertouch-sensitive keyboard, 16-note polyphony, a joystick for pitch-bend and modulation control, an eight-track MIDI sequencer, separate LFOs for vibrato and filter modulation, and ADSR envelopes.[5] Data can be stored on RAM and PCM cards.[5]
The M1 has a ROM with four megabytes of 16-bit PCM tones — a large amount at the time — including instruments that had not been used extensively in mainstream music.[5][6] The sounds include sampled attack transients, loops, sustained waveforms and percussive samples. The timbres include piano, strings, acoustic guitar, woodwinds, sitar, kalimba, wind chimes and drums.[5] Fact described the sounds as "wonderfully, endearingly wonky ... each one managed to sound simultaneously realistic and synthetic all at once".[6]
The M1 also features effects, including reverb, delay, chorus, tremolo, EQ, distortion, and Leslie simulation, an innovative inclusion at the time.[5] According to Sound on Sound, none of the M1's features were unique, but were implemented and combined in a new way.[5]
Reception
The M1 was released in 1988 and was manufactured until 1995, selling an estimated 250,000 units.[5] Reviewing it for Sound on Sound in 1988, Tony Hastings wrote that it was "destined to be big, very big", with "sensational" sounds and extensive features that outperformed its competitors.[7] It was widely used in popular music and stock music in the late 80s and early 90s.[6] The piano and organ presets were used in 1990s house music, beginning with Madonna's 1990 single "Vogue".[6]
In 2002, the Sound on Sound journalist Mark Vail wrote that the M1 was the bestselling synthesizer in history, though he noted that Korg had not verified the sales figures.[5] Both Sound and Sound and Fact described it as the most popular synthesizer of all time.[5][6] Fact attributed the success to its sampling and sequencer features, which allowed musicians to produce entire tracks without a studio before the rise of digital audio workstations.[6]
