Crumar was an Italian electronic musical instrument manufacturer established by Mario Crucianelli in the 1970s,[1] which manufactured synthesizers and keyboards during the 70s and 80s. Its name stands for "CRUcianelli and MARchetti", the names of Crucianelli and business partner Marchetti.[1]

History and products[edit]

Crumar started out manufacturing electronic pianos and string synthesizers, such as the Compac-piano (1972/1973), Compac-string (1973), Pianoman (1974) and Stringman (1974), the functions of which were combined in 1975 with the Multiman (also known as the Orchestrator), and in 1977 with the Multiman-S.[1] The company was also known for "clonewheel" organs made in the 70's and 80's, such as the Organizer (1974), Organizer T1 (1978) and T1/C (1981), T2 (1978), and T3 (1981).[1]

In 1978, Crumar released their first full-fledged synthesizer, the DS-2, which had one of the earliest digitally controlled oscillators (DCO).[2] Crumar synthesizers are comparable and contemporaneous to Moog synthesizers and other analog synthesizers; in fact, the Crumar Spirit synthesizer (1983) was designed by Bob Moog himself, along with Minimoog co-designer Jim Scott and Tom Rhea (who wrote Moog manuals).[3] In 1984,[1] Crumar began producing polyphonic synthesizers utilizing DCOs under the Bit name (Unique in the US).[3]

In the early '80's, Crumar formed a design/distribution collaborative with New York-based Music Technology (MT) in an effort to commercialize the Bell Labs Digital Synthesizer. Crumar and the MT designers worked in conjunction with some respected names in electronic music to produce the Crumar GDS (General Development System)[4] in 1980, and the Digital keyboards Synergy[5] in 1981. These synthesizers, which used additive synthesis technology and phase modulation, were bulky and cumbersome, but were state-of-the-art at the time. The complexity of this project, along with Japanese competition (notably from the Yamaha DX7) contributed to the company's eventual downfall.

Crumar ceased trading in 1987, just as they were about to launch a high-quality sampler at the lower end of the market.

In 2008 the Crumar brand was acquired by a new Italian company that soon began producing new keyboards under the Crumar name, including the Baby Grand piano (introduced at the 2008 Musikmesse), Bassman bass synth, and Mojo clonewheel organ.

Crumar users[edit]

Italian band Pooh heavily used the Crumar Compac in 1973. Keyboardist Derek Sherinian records with a Multiman-S. Space jazz musician Sun Ra occasionally played the Crumar DS-2. Duran Duran keyboardist Nick Rhodes used the Crumar Performer, known for having a string section that rivaled the more expensive ARP Solina. Pioneering Berlin School electronic musician Klaus Schulze used several Crumar instruments over his career, particularly on the albums Timewind and Moondawn; the album Dig It heavily features the Crumar GDS.[6] It can also be seen in the Mark Ronson's Bang Bang Bang music video. Composer Wendy Carlos used the GDS on the soundtrack of the film Tron, where it was employed to augment badly recorded orchestra cues. She also used both it and its sister keyboard, the Synergy, on her album Digital Moonscapes, programming all of the sounds used on it. Those sounds were later offered for the Synergy. Carlos still uses the GDS to this day. This instrument has been heard in Latin Music as well, particularly in "grupero" bands of the 70s, 80s, and 90s, like that of the Regional Mexican band Grupo Bronco (known for some time as "El Gigante de America") where the Crumar "Multi-Man" Orchestrator is the notable instrument that defines the identity of the band.
