Roland will surely not be the first company you will think of in case of mixers. But insiders esteem the excellent rack mixers from the M-Series offering many inputs at a minimum of width combined with fantastic channel separation.
As effects the popular tape echo machines of RE-Series first will be associated with Roland, on the other hand Roland is the origin of all chorus effects. Beside that Roland published the R-880 digital reverb in 1988, a serious competitor to studio standards of Lexicon and TC.
In the early 90s Roland presented the first "payable" Harddisk recording systems (DM-80) which is loved due to its excellent sound by some studios up to now. The VS-Series starting in the mid-90s became famous, because they have been a complete and portable studio, containing digital mixer, patchbay and effects.
Only insiders know and love the announcement recorders of AR-series, which you find working in several museums, sport arenas and other places with automatic announces. This series was taken over by Roland Systems Group (RSS) in 2007.
