Cutoff
The CUTOFF value sets the cutoff frequency for the
RM1x's low-pass filter. Adjusting this value changes the
voice's timbre. Settings are stored separately for each track.
Note that the filter is a low-pass type: it filters out the fre-
quencies above (higher than) the cutoff point.
Setting the cutoff to a high value will allow the high-fre-
quency harmonics (overtones) to pass, producing a rela-
tively bright sound that is true to the voice's waveform.
Setting the cutoff to a low value will block out the higher
harmonics, producing a darker and smoother sound.

These conponents pass.

Resonance
The RESONANCE value sets the resonance for the low-
pass filter. As with the CUTOFF value, the RESONANCE
setting affects the voice's timbre. Again, you can set the
value separately for each track.
The term resonance here refers to the amplification (boost)
applied to the frequencies in the vicinity of the cutoff point.
A boost to the overtones within this range can have a sig-
nificant impact on the sound. With careful adjustment, you
can get very effective resonance characteristics - such as
the body resonance of a string instrument, or the distinc-
tive slur of an analog synthesizer.
