PreDelay: 0.0�100ms Adjusts the time delay from when the direct sound begins until the chorus sound is heard. Rate: 0.05�10.0Hz LFO, Ctrl1 Adjusts the rate of modulation. Depth: 0�127 Ctrl2 Adjusts the depth of modulation. Pre Delay Dev: 0�20 Adjusts the differences in Pre Delay between each chorus sound. Depth Dev: -20�+20 Adjusts the difference in modulation depth between each chorus sound. Pan Deviation: 0�20 Ctrl3 Adjusts the difference in stereo location between each chorus sound. With a setting of 0, all chorus sounds will be in the center. Increasing the value will cause the chorus sound to be panned more expansively. Effect Level: 0�127 RTM Adjusts the output level of chorus sound. Direct Level: 0�127 Adjusts the output level of direct sound.

Trm Phase: 0�180deg Ctrl3 Adjusts the spread of the tremolo effect. Trm Rate: 0.05�10.0Hz Ctrl1 Adjusts the modulation speed of the tremolo effect. Trm Depth: 0�127 Ctrl2 Adjusts the modulation depth of the tremolo effect. Effect Level: 0�127 RTM Adjusts the output level of tremolo chorus sound.
