MFX Parameters

Modulation Type
Ring Mod (Ring modulator)
This is an effect 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 effect.
Parameter Value Explanation
Frequency 0–127 Adjusts the frequency at which modulation is applied.
Sens 0–127 Adjusts the amount of frequency modulation applied.
Polarity
UP, DOWN Determines whether the frequency modulation moves towards higher frequencies or lower
frequencies.
UP: The filter will change toward a higher frequency.
DOWN: The filter will change toward a lower frequency.
Low Gain -15–+15 [dB] Amount of boost/cut for the low-frequency range
High Gain -15–+15 [dB] Amount of boost/cut for the high-frequency range
Balance
D100: 0W–D0:
100W Volume balance between the direct sound (D) and the effect sound (W)
Level 0–127 Output Level
