8. Voice Edit t Filter Track number Transpose PATTERN MODE Parameter Cutoff Resonance Track number Transpose Values -64 ... 0 ... +63 -64 ... 0 ... +63 01 ... 16 -36 ... 0 ... +36 Function Sets the filter cutoff frequency. See below for detail. Sets the filter resonance. See below for detail. Shows the current selected track number. Track number selection can be accomplished via this parameter, or by the keyboard method described on page 27. Shows the current transpose value. Transposition can be accomplished via this parameter, or by the keyboard method described on page 27. * For information about how to change values, refer to the Basic Operation (page26). 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 frequencies above (higher than) the cutoff point. Setting the cutoff to a high value will allow the high-frequency harmonics (overtones) to pass, producing a relatively 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. Loudness These conponents pass. These components are eliminated. Harmonics Cutoff frequency Frequency Resonance The RESONANCE value sets the resonance for the lowpass 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 significant 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 distinctive slur of an analog synthesizer.
