Yamaha CX5M is an MSX-system compatible computer that expands upon the normal features expected from these systems with a built-in eight-voice FM synthesizer module, introduced in 1984 by Yamaha Corporation.〔 (【引用サイトリンク】 url = http://www.sonicstate.com/synth/cx5m/ )〕 This FM synth itself has stereo audio outputs, an input for a purpose-built four-octave keyboard, and a pair of MIDI Input/Output ports that could be used for normal MIDI on the second revision of the CX5M but only management of data from a Yamaha DX7 on the first model. ==Specification== The CX5M was built to the MSX standard, which included slots for inserting programmed cartridges. These extended the machine's capability, accepting a range of games, office applications and so on. Yamaha produced a range of cartridges including a programmer for Yamaha's DX range of FM keyboards and a real-time sequencer. Two of these, the ''Voice Editor'' and ''Music Composer'', allowed the user to program a bank of 48 sounds for the CX5's own built in synthesizer and to sequence up to eight channels of music, controlling the built-in module or external instruments via MIDI, in step-time using a musical-stave input screen. Three versions of the CX5M were released. The first contained as its FM module the SFG-01, which did could not receive MIDI note information from externally; it required a proprietary keyboard and only used its MIDI port as an output to send data to Yamaha's then-flagship DX7. The second version, the CX5M II (or CX7M/128 in Japan〔 (【引用サイトリンク】 url = http://jp.yamaha.com/product_archive/music-production/cx7m_128/?mode=model ) — for details, see CX7/128.〕〔 (【引用サイトリンク】 url = http://jp.yamaha.com/product_archive/music-production/cx7_128/?mode=model ) 〕), upgraded the FM system to the SFG-05, which supported MIDI input and thus allowed the internal FM synth to be played by any external MIDI keyboard. There was also a later CX5M II with some smaller differences.〔 (【引用サイトリンク】 title = CX5M FAQ )〕 Later, Yamaha released the Yamaha FB-01 module, which was effectively an SFG-05 in a standalone, portable case.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yamaha CX5M」の詳細全文を読む スポンサード リンク
