2: FEEDBACK
Feedback can be applied to one operator in each algorithm. Pressing this button
permits setting the amount (level) of feedback which will be applied.
The feedback level range is from 0 to 7. At 0, feedback is OFF, and at 7 maximum
feedback is applied.
Data is entered via the DATA ENTRY slider or buttons.
The LFO
"LFO" stands for Low Frequency Oscillator. This oscillator is used to apply mod-
ulation effects such as tremolo or vibrato to the DX100 voices. By setting the LFO
WAVE, SPEED, and SYNC parameters, you determine the effect that will be applied
to the currently selected voice when the modulation wheel or breath controller is
operated. The effect can also be applied without using the Wheel or Breath Controller
by adjusting the AMD and PMD parameters. The LFO parameters work together
with the MODULATION SENSITIVITY (9 and 10) parameters, and these must be
set carefully to achieve the desired effect.
3: LFO WAVE
Permits selection of the low frequency oscillator waveform. The available waveforms
are SAW UP (a rising sawtooth waveform), SQUARE, TRIANGL, and S/HOLD
(sample and hold). When used in conjunction with LFO SPEED, DELAY, LFO PMD,
and LFO AMD, a vast range of phase shifting and flanging-type effects can be
obtained. And depending upon the depth of your individual settings for any par-
ticular voice, these effects could range from subtle, sympathetic coloration of a
"piano" voice, or a "pipe organ" voice with an extremely broad low-frequency
sweep.

These waveforms are selected using the DATA ENTRY slider or buttons.
4: LFO SPEED
Permits setting the speed of the low frequency oscillator. The data range is from
0 to 99.0 corresponds to the slowest LFO speed (0.0008 Hz), and 99 corresponds
to the fastest LFO speed (55 Hz).
