PARAM (Direct-Control Parameter for FX3)
This direct-control parameter works in a similar fashion as the one for FX1.
DIGFX (Digital Sampling Effects)
This effect module emulates the effect that different variations of digital sampling can have on an audio
signal.
LEVEL
In this position, the display shows you the output level of the current program.
12
For Doubling, Ping Pong, Tape Delay and Stereo Delay, indicates the length of the
delay, up to one second for Tape Delay and up to half a second for the others.
For Chorus, indicates the rate of the chorus.
For Flanger, indicates the rate of the flanger.
For Rotary Speaker, indicates the rate of the speaker rotation.
For Pedal Pitch Transpose Up and Down, indicates the amount of pitch change in 1/4
semitones (from 1/4 semitone to more than 2 octaves). Wet/dry mix is fixed at 100%
wet.
For all reverbs, higher values indicate a longer decay.
For fixed-interval Pitch Transpose, indicates the wet/dry mix from 0 (100% dry) to 10
(50% dry, 50% wet) to 20 (100% wet).
Indicates that the expression pedal controls the parameter.
Indicates FX3 is off.
Sample Rate Decimation
Lower values indicate lower decimation frequency (more decimation, more aliasing).
Pedal Sample Rate Decimation
A sample rate decimator effect controlled by the expression pedal.
Bit Reduction
Higher values indicate lower resultant bit depth.
Pedal Bit Reduction
Bit Reduction effect controlled by the expression pedal.
Off
Indicates that DIGFX is off.
Level
Indicates the program output level in 2dB steps, where 25 is unity gain (0dB). Unity
gain is the point at which the level of the output is the same as the level of the input.
Pedal-Controlled Level
Program level that is controlled by the expression pedal.
