modulated.
Up: The lter will change
toward a higher frequency.
Down: The lter will change
toward a lower frequency.

for switching the vowels is
reset by the input signal (ON)
or not (OFF).

equal duration.
51 or more: Vowel 2 will have
a longer duration.

7012b: Ring Modulator
This is an eect that applies amplitude modulation (AM) to the input signal,
producing bell-like sounds. You can also change the modulation frequency in
response to changes in the volume of the sound sent into the eect.
No Parameter Value Description
1 Frequency #1 0 –127 0–127
Adjusts the frequency at
which modulation is applied.
2 Sens 0–127 0 –127
Adjusts the amount of
frequency modulation
applied.
3 Polarity 0–1 Up, Down
Determines whether the
frequency modulation moves
towards higher frequencies
(Up) or lower frequencies
(Down).
4 Low Gain 0–30 -15–+15 dB
Gain of the low frequency
range
5 High Gain 0–30 -15–+15 dB

range
6 Balance #2 0–100
D100:0W–
D0:100W
