An Overview of the MC-909
Editing performance data
Unlike a cassette tape or MD, a sequencer records a
performance as musical data (not as sound). It’s easy to edit the
performance data to create your own original patterns.
The controller section
The “controllers” of the MC-909 are its velocity pads, D Beam
controllers, and the panel knobs and sliders. By operating these
controllers you can modify the performance and sound in various
ways.
Velocity pads
These pads function just like a music keyboard. They are also
used to trigger RPS (p. 28) and the arpeggiator (p. 30).
Normally, pad number 2 will be C4. The force with which you
strike a pad will control the velocity (dynamics) of the note.
D Beam controllers
By passing your hand over these controllers you can play or
modify sounds (p. 35).
Turntable emulation
These buttons and slider allow realtime synchronized
performance with sound sources such as a turntable, assisting
you with DJ performance (p. 36).
Realtime modify knobs
These knobs and sliders give you realtime control over sound
parameters such as filter cutoff frequency and resonance or LFO
speed.
The sampler section
A sampler is a device that captures sounds from a wave file or an
external source such as a CD.
On the MC-909, a sampled sound can be handled just like an internal
waveform of the sound generation section; you can change the pitch
of the sampled sound, apply a filter to it, or modify its envelope.
Adjusting the display
contrast
Use the [LCD CONTRAST] knob located at the right of the display to
adjust the contrast.
Turn the knob toward the right to darken the screen, or toward the
left to lighten it.
Editing a value
Use the [VALUE] dial to make large changes in a value, or use the
[INC]/[DEC] buttons to change a value in steps of one. Your
changes will affect the value that is displayed in white characters
within a black frame in the screen. This location is called the
“cursor.” If a screen contains more than one value that can be edited,
use the [CURSOR] buttons to move the cursor to the value you want
to edit.
Quickly changing a value
• If you hold down [SHIFT] while you turn the [VALUE] dial, the
value will change more rapidly.
Key Repeat function
• The value will continue changing if you press and hold [INC] or
[DEC].
• The cursor will continue moving if you press and hold a
[CURSOR] key.
Turbo Repeat function
• The value will increase rapidly if you hold down [INC], then
press and hold [DEC].
• The value will decrease rapidly if you hold down [DEC], then
press and hold [INC].
• The cursor will move rapidly if you hold down a [CURSOR]
button and then press the opposite [CURSOR] button.
Saving your data
After editing settings or recording a performance, you must save
your data if you want to keep the results. If you turn off the power
without saving, your settings or recorded performance will be lost.
For details on saving your data, refer to the following pages.
• Saving a pattern (p. 50)
• Saving a Patch/Rhythm Set (p. 77)
• Saving a song (p. 85)
• Saving a sample (p. 123)
• Saving a Pattern Set (p. 27)
• Saving an RPS set (p. 30)
• Saving an arpeggio style (p. 32)
• Saving a chord form (p. 33)
Saving takes several seconds. Do not turn off the power until saving
is completed. Doing so may cause the MC-909 to malfunction.
