FILTER Function Chapter 5 Knob 3 Knob 4 Knob 5 LowPass2 HiPass1 HiPass2 BandPass BandElim Low Pass Level Low-pass filter #2. Offers much higher Q (resonance) than lowpass filter #1. High-pass filter #1. (A high-pass filter blocks out all frequencies below the cutoff frequency.) High-pass filter #2. Offers much higher Q (resonance) than highpass filter #1. Band-pass filter. (Allows only frequencies near the cutoff frequency to pass; blocks out all higher and lower frequencies.) Band-eliminate filter. (Blocks out the frequency range around the cutoff frequency, while allowing higher and lower frequencies to pass.) Q emphasis High Pass Level Q emphasis These frequencies pass. These frequencies are cut. Cutoff Frequency Band Pass Level These frequencies pass. These frequencies are cut. These frequencies are cut. Cutoff Frequency These frequencies are cut. These frequencies pass. Cutoff Frequency Band-Eliminate Level These frequencies are cut. These frequencies pass. These frequencies pass. Cutoff Frequency Cutoff = 0,...,127 Use this knob to set the filter's cutoff frequency. FltGain = -31,...,+31 • Use this knob to set the filter's output level. • Note that high settings may produce distortion when used with certain sample sounds or when many samples are played together. Q/Width = 0,...,31 This knob sets the Q value (resonance) or width setting, depending on the filter type. • If you select a low-pass or high-pass filter, this setting selects the Q value. The Q value determines the amount of emphasis applied to frequencies that are very close the cutoff point. (See drawing above.) Higher settings produce stronger emphasis. Note that high settings for a LowPass2 or HiPass2 filter may produce distortion with certain samples. • If you select the band-pass filter, this setting determines the width of the band that is allowed to pass. Increasing the setting will widen the band, allowing more frequencies to pass. • If you select the band-eliminate filter, this setting determines the width of the frequency ranges that are allowed to pass. Increasing the setting will allow more frequencies to pass (will reduce the elimination zone). Note that the elimination band itself becomes narrower as you increase the value. Chapter 5 EDIT Mode 183
