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

, 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.

Applications

Inexpensive multitimbral synthesizers combined with a

equipped computer made home studio recording much more accessible to the digital musician, particularly

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 Reel-to-reel audio tape recording, also called open-reel recording, is magnetic tape audio recording in which the recording tape is spooled between reels. To prepare for use, the ''supply reel'' (or ''feed reel'') containing the tape is plac ...

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.
