Monotimbral (from the root prefix ''mono'' meaning one, and ''
timbre
In music, timbre ( ), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musica ...

Monaural or monophonic sound reproduction (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduc ...

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

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

s 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
Polyphony ( ) is a type of musical texture consisting of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice, monophony, or a texture with one dominant melodic voice accompanied by chords, ...

players. By capturing information digitally via MIDI, one could play back an entire work with several voices on a single multitimbral synthesizer. This, combined with a relatively cheap four track tape machine or higher-end 16 and 24 track
reel-to-reel machines would allow a musician to layer a number of keyboard tracks digitally, and then use a single track for MIDI information and the rest for analogue sounds, without requiring intermediate mix-downs to gain additional needed synth tracks.
