An overview of the MC-808
Overview
Songs
fig.02-006.e
A song consists of one or more patterns connected in the
desired playback order.
You can specify a playback order consisting of up to fifty
patterns.
Patterns and Parts
fig.02-007.e
A pattern contains 1–998 measures of performance data that
plays the sounds (patches or rhythm sets) of up to sixteen parts.
The MC-808 provides 256 patterns.
Each part is analogous to a musician in a band or orchestra. The
MC-808 has sixteen parts, meaning that you can use sixteen
different patches or rhythm sets to play sixteen different
performances simultaneously.
Patches and Tones
fig.2-008.e
A patch corresponds to a single instrument such as a piano or
guitar. Each patch consists of up to four tones. The MC-808
provides 896 different patches, giving you a wide variety of
sounds that you can enjoy simply by selecting and playing
them.
Tones are the building blocks of which a patch is made. The
MC-808 provides 622 waveforms, and two waveforms can be
assigned to a tone. (They can be assigned in stereo, with one for
the L side and one for the R side.)
Rhythm sets
fig.02-008.e
A rhythm set assigns a separate instrumental sound to each
note. (You can’t play scales or melodies using each instrumental
sound.) The MC-808 provides 128 rhythm sets.
Effect processors
The effect processors let you add a variety of effects to the
sounds of the patches or rhythm sets. You can use six different
effects simultaneously, using the six independent effect
processors: Compressor (which evens-out irregularities in the
level), Reverb (which adds reverberation), two Multi-effects
(each of which lets you choose one of 47 effect types such as
equalizer, overdrive, and delay), an External Input effect, and a
Master effect (which is applied to the final output of the MC-
808, making the overall volume more consistent).
Sampler
A sampler is a device that captures wave files or external audio
sources such as a CD as “samples.”
The MC-808 lets you change the pitch of a sampled sound,
apply a filter to it, or modify its envelope, treating sampled
sounds in the same way as the waveforms provided by the
sound generator section.
