At ''0" the solo tone does not pass via the ring modulator.
At "3" the solo tone passes only through the ring modulator.
Between ''0" and ''3"' the two types are continuously mixed.
This also pertains to the following section.
Solo tones undergo ring modulation using noise.
*The
above
noise element
is changed
by
a random
signal with an
approximate
10Hz cycle when the setting is ''0'', and with a 10KHz
cycle when the setting is ''3''.
The solo tone undergoes ring modulation using a_~7
waveform.
*The above cycle is changed between 1.7 and 28Hz.
According to the above cycle as set by the OSC speed value:
a) There is no change when the solo key C3 is pressed.
b) There is a one-octave rise when solo key C4 is pressed.
c) There is a three-octave rise when solo key C6 is pressed.
The above changes (a) — (c) are continuous.
The value is held even when the key is off.
*With regard to the ring modulator:
This modulator Gan be thought of as two units in parallel.
For ex-
ample, if two signals,
A and B, modulate each other but only out-
put from
one
is desired,
the modulated
waveform
becomes that
shown in line 1 of Fig. A: a DSD wave with no carrier.
