The Yamaha Motif is a series of music workstation synthesizers, first released by Yamaha Corporation in August 2001. The Motif replaced the EX series in Yamaha's line-up and was also based on the early Yamaha S series. Other workstations in the same class are the Korg Kronos and the Roland Fantom G. The series' successor is Yamaha Montage. Products MOTIF Classic Original MOTIF series, now called "MOTIF Classic", were released in four variants in 2001: The balanced hammer effect action is the same action found on Yamaha S90 series keyboards. MOTIF Rack is a sound module (with no keyboard) that is controlled by external MIDI instruments. It can be expanded with two Modular Synthesis Plug-in boards but has no sampling capabilities. MM In January (2007), Yamaha introduced two "retro" models; the MM6 (61 keys) and MM8 (88 keys), both based on the original 2001 Motif sound set and samples, with polyphony greatly reduced to fit the lower specifications. This synthesizer comes default with 418 patches and 22 drum kits. GHS (Graded Hammer Standard) action is the same action on Yamaha's high end digital pianos. MOTIF ES MOTIF ES, a successor to original MOTIF series, debuted at Summer NAMM Show in 2003: MO In January 2006, Yamaha launched two entry-level variants of the MOTIF ES - the 61 key MO6 and 88 key MO8. Though containing half the polyphony and fewer preset sound programs, these models contain all the MOTIF ES sample sets, along with arpeggios and a song and pattern sequencer. Lacking are the professional MOTIF ES features such as mLAN connectivity, Yamaha PLG integration, sampling and multiple foot controllers. MOTIF XS The XS versions were announced at NAMM 2007: MOTIF has a mLAN connection for transferring MIDI and sound to a PC. The MOTIF XS operating system is based on MontaVista Linux. MOX In 2011, Yamaha introduced an entry-level variant of the MOTIF XS: the 61-key MOX6 and 88-key MOX8. Though containing half the polyphony and fewer insert effects of the XS, the MoX series contains all the MOTIF XS Wave ROM and voice presets, along with arpeggios and a song and pattern sequencer. The number of performances in the MoX is reduced to 256. The MoX does not support user sampling, nor does it support the mLAN/FireWire expansion. The MoX feature a built-in 4-out/2-in USB audio interface users can use to record audio directly from the keyboard or
