'''Roland D-50''' is a LA synthesizer released in 1987. LA synthesis is a method that combines PCM samples and subtractive analog waveforms (square or sawtooth).
The '''Roland D-50''' is a synthesiser released in 1987. It is notable for being the first synthesiser to employ the ''linear arithmetic synthesis'', or LA synthesis for short, as a method of producing sound, which employs 2 analog-like voices with subtractive filtering, and two PCM tones, usually reserved for transients or short acoustic type sounds. A rackmount version, known as the ''D-550'', was released as well.


It was regarded as an influential synthesizer in the late 1980s - many presets like Fantasia, Staccato Heaven, Pizzagogo, and DigitalNativeDance have been used in the pop songs of that era.
The D-50 and D-550 could interface with Roland's own PG-1000 synthesiser programmer, designed to provide hands-on control to all synthesis parameters. Nowadays it is also possible to upgrade the firmware to various third-party solutions to give it more features.<ref>[https://web.archive.org/web/20150606075921/http://www.soundonsound.com/sos/1997_articles/jul97/rolandd50.html Paul Ward via Sound on Sound, June 1997 issue (archived)], "Several operating-system upgrades were made available by third-party companies.

It was, and is still regarded as an influential synthesiser.

The Roland D-50 is a synthesiser released in 1987. It is notable for being the first synthesiser to employ the linear arithmetic synthesis, or LA synthesis for short, as a method of producing sound, which employs 2 analog-like voices with subtractive filtering, and two PCM tones, usually reserved for transients or short acoustic type sounds. A rackmount version, known as the D-550, was released as well.

The D-50 and D-550 could interface with Roland's own PG-1000 synthesiser programmer, designed to provide hands-on control to all synthesis parameters. Nowadays it is also possible to upgrade the firmware to various third-party solutions to give it more features.[2]

It was, and is still regarded as an influential synthesiser. Many of its presets, such as Fantasia, Pizzagogo, DigitalNativeDance and so on have seen a lot of use throughout the late 80s and 90s media, and the synthesis engine would go on to inspire the creation of the D-70, which itself would go on and ultimately lay a foundation to the Roland JV series. Its synthesis methods would also be transformed and shrunk down for use on the Roland MT-32 and other related products.

Rereleases

Roland D-05

The Roland D-50 would get a reissue in 2017 starting with the Roland Boutique D-05 synthesiser - it is in essence a compact module variant, still exposing all the controls of the keyboard, and includes an extra 5 banks of patches, as well as user storage space for up to 8 banks of 64 patches each.[3]

Otherwise, the feature set would stay the same, with the same polyphony limit and same selections of sounds and filters.

Roland Cloud D-50

Also in 2017, Roland would reissue the D-50 in software form via their Roland Cloud subscription service.[4] This is the first time that Roland would officially issue a complete emulation of the D-50 in software form. It allows for SysEx files from the D-50 to be loaded as banks of patches as well.
