Effect Buttons 36-40 are used to activate the desired Effect. Holding an Effect button puts the Effect into a
Hold or Alternate Effect mode. Once an effect is active, rotate the jog wheel to get the desired effect
sound. The parameter value will show in the display. You can preset a desired value by holding the
button and rotating the wheel.
36. Sonar – creates a metallic hollow effect to the audio. Pressing and holding this button will keep the
sound from automatically returning to normal when movement stops. Tapping the button will turn the
effect on and off at the desired setting.
37. Slide - smoothly changes the key of the music. In the key display you will see the key change as the
wheel is moved. Pressing and holding this button will keep the sound from automatically returning to
normal when movement stops. Tapping the button will turn the effect on and off at the desired setting.
38. Echo - adds echo to the music also based upon the
Beatkeeper™. The start parameter is no echo "0". If you
move the wheel to the right the numbers will go 1-64, 1-32,
1-16, 1-8, 1-4, 1-2, and 1-1 indicating the amount of echo
added to the unit. If you move the wheel to the left you will
create negative or preceding echo. This essentially plays the
music before you get to it. At 1-1 the music will echo 1 full
measure or 4 beats of music. If you turn off the effect then
back on again it remembers the last set parameter. (Note: a
preceding echo requires the unit to play from buffer memory.
If the buffer becomes unavailable the effect will stop until buffer is regained.)
A.D. (hold the Echo button to activate)- stands for "Auto Decimation". It reduces the bit rate of the
music, creating increasing distortion. To activate this effect, hold the "Echo" button for 2 seconds.
39. Filter – is an isolation (bandpass) filter that lets you play only a specific frequency of the music.
Rotation of the wheel moves the filter frequency. If you turn off the effect, then on again, it remembers
the last set parameter.
KILL (hold the Filter button to activate)- This elimination (bandstop) filter lets you play all but a
specified frequency. To activate, hold "Filter" for 2 seconds. Rotation of the wheel moves the filter
frequency. If you turn off the effect, then on again, it remembers the last set parameter value.
40. Chop – breaks up the music by turning the volume on and off based upon the BPM of the Beatkeeper™.
This effect works best when the Beatkeeper™ is properly aligned. First activation of this effect plays
1/8th note or half of every beat. The BPM display will indicate "1-8", which means one measure (4
beats) of music has been broken into 8 parts. Rotation of the
wheel to the left decreases the parts to 1-4, 1-2, and 1-1. At
1-1 the music plays for 4 beats then is silent. Rotating to the
right breaks up the music into 1-16, 1-32, 1-64, then smaller
increments, creating another interesting effect. When the
effect is first activated, the music will play the section then
turn off for a section. This is important because you can
reverse the sections that are on and off by activating the
effect in the other section. If you deactivate the effect, then
turn it on again, it remembers the last set parameter value.
Pan (hold the Chop button to activate)- alternates playing right and left audio based upon the BPM of the
Beatkeeper™. This effect works best when the
Beatkeeper™ is properly aligned. To activate, hold "Chop"
for 2 seconds. First activation of the effect alternates on
1/8th notes or half of every beat. The BPM display will
indicate an "1-8", which means one measure (4 beats) of
music has been broken into 8 parts. Rotation of the wheel
to the left decreases the parts to 1-4, 1-2, and 1-1.
Rotating to the right makes faster changes of 1-16, 1-32,
1-64, then smaller increments, creating another interesting
effect. If you deactivate the effect then turn it on again, it
remembers the last set parameter value.
