With positive (+) values, the resonance will increase as you play more strong-
ly, and as you play more softly the resonance will approach the level speci-
fied by the Resonance setting.
With negative (–) values, the resonance will decrease as you play more
strongly, and as you play more softly the resonance will approach the level
specified by the Resonance setting.
The resonance level is determined by summing the Resonance and Intensity
values.
