Reverb + Chorus (PRESET bank) Reverb → Chorus (PRESET bank) Reverb + Chorus separately applies reverb and chorus to the original sound, and then mixes the results. Reverb → Chorus applies reverb to the original sound and then applies chorus. Each aspect of the sound is controlled by the following effect parameters. Reverb: REV TIME, HI.RATIO, INI.DLY, DIFF., DENSITY Chorus: FREQ., AM DEPTH, PM DEPTH, MOD.DLY, WAVE Balance of reverb and chorus: REV/CHO, REV.BAL Filter/equalizer: HPF, LPF Tempo synchronization: SYNC, NOTE, TEMPO Output level: OUT LVL, MIX BAL.

Range 0-100% OUT LVL 0-100% HPF Thru, 21.2 Hz-8.00 kHz LPF REV/CHO REV.BAL SYNC NOTE TEMPO *a. 50.0 Hz-16.0 kHz, Thru 0-100% 0-100% ON, OFF *a 25-300 Explanation Speed of modulation (AM, PM). Increasing this value will make the modulation repeat at a shorter interval. Amplitude modulation (AM) depth. Increasing this value will produce greater volume change. Pitch modulation (PM) depth. Increasing this value will produce greater pitch change. Delay of the effect sound relative to the original sound. Waveform of the modulation signal. This will affect the character of the modulation. You can choose Sine (sine wave) or Tri (triangle wave). Reverb time. This is expressed as the time over which reverberation at 1 kHz will decay by 60 dB. Reverb time for the high-frequency range, expressed as a proportion of REV TIME. If this value is 0.1 the time will be 1/10th the REV TIME; if it is 1.0 the time will be the same as the REV TIME. You can adjust these values to simulate the absorptiveness of the walls or ceiling. HI.RATIO is the decay of the high-frequency range. Delay of the early reflections relative to the original sound. This also affects the delay until the reverberation is heard. Diffusion of the sound to left and right. Increasing this value will make the reverberation more spaciousness. Density of the reverberation. Increasing this value will make the reverberation smoother. You can create unique effects by lowering this value. Explanation Balance between the original sound and effect sound. At a setting of 0% only the original sound will be output; at a setting of 100% only the effect sound will be output. Output level after the original sound and effect sound have been mixed. Decrease this value if you want to lower the output. At a setting of 0% there will be no output. A filter that cuts the low-frequency portion of the effect. Frequency components lower than the frequency specified here will be cut. With a setting of Thru this filter will do nothing. This filter does not affect the original sound. A filter that cuts the high-frequency portion of the effect. Frequency components above the frequency specified here will be cut. With a setting of Thru this filter will do nothing. This filter does not affect the original sound. (Reverb + Chorus only) Balance between the reverb and chorus. A setting of 0% outputs only the reverb; a setting of 100% outputs only the chorus. (Reverb → Chorus only) Amount of chorus. Raising this value will strengthen the chorus effect. At a setting of 0% only reverb will be heard. Switches tempo synchronization on/off. If this is ON, the speed of modulation will synchronize to the tempo synchronization source specified by "TEMPO SOURCE" (page 23). The NOTE value will be set to the synchronized tempo value. This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set according to this value and TEMPO. If SYNC is OFF, this value is ignored. This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set according to this value and NOTE. If SYNC is OFF, this value is ignored. 68 SPX2000-Owner's Manual
