Functions of Front Panel Components
DX
y-1. [FREQ] (frequency) button
For displaying the Operator Frequency Set-
tings screen. If you flick at a certain speed or
greater, the setting will change to the closest
integer value. For example, if the current set-
ting is 9.29 and you flick quickly upward, the
value will change to 10.00.
Frequencies can be specified as either a ratio
or a fixed frequency. Refer to the “Reference
Manual” (a digital manual) for details on the
setting procedure.
y-2. [ALGO] (Algorithm) button
For displaying the Algorithm Setting screen.
On this screen, you can specify how the four
operators should be combined. A total of 12
algorithms are available.
y-3. [LEVEL] button
For displaying the Operator Level Settings
screen. On this screen, you can adjust the vol-
ume (for carriers) or the degree to which the
corresponding carrier is modulated (for mod-
ulators).
y-4. [FB] (Feedback) button
For displaying the Feedback Settings screen.
Waveforms can be changed by feeding some
of the signal generated by an operator back
through that operator.
The reface DX allows you to set feedback
levels for each of the operators. If, for exam-
ple, you were to select Algorithm No. 8 and
apply feedback to all of the operators, the sig-
nal flow would be as follows.
If you move the slider up from the center
position, the feedback type becomes saw-
tooth ( ) and the feedback level will
increase. As a result, the waveform morphs
from a sine to a sawtooth shape, and at the
maximum level, it is transformed fully into a
sawtooth wave. If you move the slider down
from the center position, the feedback type
becomes square ( ) and the feedback level
will increase. As a result, the waveform
morphs from a sine to a square shape, and at
the maximum level, it is transformed fully
into a square wave. At the center position, the
feedback level is “0.” Here, none of the signal
is fed back and a sine wave is produced.
NOTICE
Take special care when setting a low carrier
frequency in FIXED mode as this action can
damage the speakers.
