Monotimbral (from the root prefix ''mono'' meaning one, and ''timbre'' meaning a specific tone of a sound independent of its pitch) is usually used in reference to electronic synthesisers which can produce a single timbre at a given pitch upon pressing a single (if the synth is monophonic) or multiple keys (if the synth is polyphonic). An electronic musical instrument may be multitimbral, which means it can produce two or more ''timbres'' (also called ''sounds'' or ''patches'') at the same time. Instruments which may be multitimbral include synthesizers, samplers, and music workstations. A multitimbral instrument might be configurable in a variety of ways: *Splitting the keyboard at a given point allows a musician to play, for example, a bass guitar sound with the left hand and a piano sound with the right hand. *Layering timbres allows a musician to play, for example, a pipe organ sound and a string ensemble sound together. *Combinations of keyboard splits and layers may be possible. *An external sequencer might play an accompaniment of bass and drum sounds on the instrument (actuated through MIDI) while the musician plays a piano part on the keyboard of the same instrument. ==Background== Multitimbrality is achieved by having a synthesizer with more than one sound producing module. In a fully digital system, each sound module is virtual, since in reality algorithms combine samples together in real time for output to a single D-A (digital to analogue) circuit. Synthesizers that can combine ''n'' timbres together are called ''n'' voice multitimbral. For example, a synthesizer capable of playing eight voices or ''timbres'' at one time would be an ''eight voice multitimbral'' instrument. Multitimbrality is distinct from polyphony, which is the number of notes which can be played at the same time, not the number of different timbres. All multitimbral instruments are polyphonic, but not all polyphonic instruments are multitimbral. 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「Timbrality」の詳細全文を読む スポンサード リンク
