FUNCTIONS & FEAT U R E S
The DFX-1 effect processor was designed for easy and effective real-time
control over the music in live applications - although it works really well in
a studio environment too. The trackball controls the effect parameters for
easy single handed control in live situations when many things often need
to happen at the same time.
PROGRAMS
The DFX-1 features 85 unique effect programs constructed from 8 main
effects: Echo, Auto Pan, Transformer, Flanger, Manual Filter, Auto Filter,
Reverb, and Pitch Shifter. Aside from these 8 single effects, the other pro-
grams are combinations. in which 2 of the above effects are daisy
chained in the signal path. For these combination presets, only the first
effect in the chain can be controlled while the second remains static. The
list below shows the speed of the second effects in beats. For example,
for Program 01, the audio will be panned left to right every 1/2 beat
according to the BPM counter readout.
PROGRAM WHEEL
The Program wheel is used to search and select the effect Programs.
There are 85 Programs in the DFX-1. To scroll through the Program bank,
just turn the wheel in either direction. When the Program wheel is turned,
the Program number on the LCD display will begin flashing with the new
Program number. Push down to select the desired Program. The display
will keep flashing until a new Program is selected. If a new Program is not
selected within 5 seconds, the display will return to the current Program.
To select a program:
1. Rotate the program wheel
to the desired program
2. Press wheel down to select.
FUNCTIONS & FEAT U R E S
FUNCTION KEYS
The 5 Function keys located under the LCD display serve two purposes.
They control the same effect parameter as the Trackball’s X axis (see
control chart) and are also used for various functions when the SHIFT key
is held down. More about the SHIFT key on the next page.
For all effects (except the Manual filter and the Reverb), the X parameter
equals the speed of the effect. In this case, the function keys will act as
“Beat Selectors” to change the speed of the effect in time with the music
(according to the BPM count). From left to right, the keys are marked 1/2,
3/4, 1/1, 2/1, and 4/1. These numbers refer to the beat count picked up
by the BPM counter. 1/1 is one beat. By pressing the 1/1 key, the effect
will regenerate on every beat. Pressing 1/2 will make the effect regener-
ate every half beat, and so on.
(TIP: These keys affect the same effect
parameter as the trackball’s X axis. Use them together to create various
rhythmic effects).
For the Manual Filter, the function keys control the frequency cut-off, and
for the Reverb, they control the feedback.
The beat selectors also act as starting points for the effects to let the unit
know where the first beat is, and together with the BPM counter makes
sure the effects are synchronized. The LED above each button will light
up in green to show the selected Function key.
To ch a n ge the speed* of an effect :
Press any Function Key: 1/2 for a half beat, 3/4
for 3/4 of a beat, 1/1 for every beat, 2/1 for every
2 beats, and 4/1 for ever 4 beats.
* The Functions Keys control the speed of the Echo, Pan , Flanger, Transformer, and Auto-
Filter effects. For the Manual Filter, the function keys control the frequency cut-off, and for
the Reverb, they control the feedback, as they are not rhythmic effects.
