An Overview of the MC-909
 
Basic structure of the MC-
 
909
 
This section provides an overview of the sequencer section, sound 
generator section, controller section, and sampler section, which 
make up the main parts of the MC-909.

The sound generator section
 
This is the section that actually generates the sound. It produces 
sounds in response to data received from the MC-909’s Controller or 
Sequencer sections. You can also play the sound generator by 
sending it performance data from an external MIDI device.
Since the sound generator section of the MC-909 is able to play up to 
64 notes simultaneously, it can easily handle multiple parts.
 
Song
 
Two or more patterns connected in the order of playback are 
called a song.
In one song, you can register up to 50 patterns in the desired 
order of playback.
 
Pattern
 
A pattern is 1–998 measures of performance data consisting of 
sounds (patches or rhythm sets) for up to 16 parts.
The MC-909 provides 215 different preset patterns.
 
Part
 
A part corresponds to a single musician in a band or orchestra. 
Since the MC-909 has sixteen parts, you can use sixteen 
different patches or rhythm sets to play as many as sixteen 
performances simultaneously.
 
Patch
 
A patch corresponds to a single instrument such as a piano or 
guitar. A patch consists of up to four “tones.” The MC-909 
provides 800 different patches, and you can enjoy an enormous 
variety of sounds simply by choosing from these patches.
 
Rhythm set
 
A rhythm set assigns a separate instrumental sound to each 
note of the keyboard. These instrumental sounds are not played 
as a scale. The MC-909 provides 64 preset rhythm sets.

Tones
 
Tones are the raw materials of sound that are combined to 
create a patch. The MC-909 provides 693 different waveforms, 
and two waveforms can be assigned to each tone. (Waveforms 
can be assigned in stereo; one for L and one for R.)
You can install separately sold wave expansion boards (SRX 
series) to add more waveforms, and sounds that you sample 
can also be used as waveforms.
 
Effects
 
Effects let you apply a variety of special effects to patches or 
rhythm sets. You can use four effects simultaneously: 
compressor (an effect that makes the sound more consistent), 
reverb (which adds reverberation), and two multi-effects (each 
selectable from 47 types such as equalizer, overdrive, and 
delay).
 
The sequencer section
 
 
sequencer
 
 is a device that records musical performance data, and 
can play back the performance data that was recorded.
The MC-909 is a sequencer that plays back patterns and adds 
changes to the playback method. This type of sequencer is referred 
to as a 
 
pattern sequencer
 
.
 
Recording/playing a performance
 
The MC-909 comes with 215 previously prepared patterns 
(
 
preset patterns
 
). These preset patterns can be played back 
easily.
You can also create your own original patterns, either by 
modifying preset patterns or by creating a pattern from scratch.
 
Simultaneous playback of multiple parts
 
The MC-909 is able to play multiple sounds (patches) 
simultaneously. For example, with the following part 
configuration, you can simultaneously play drums, bass, piano 
and guitar; and the resulting performance will sound like a 
band.
