The Chorus Editor
The programmable chorusing feature in the K150X can be used to create a variety of effects such as phasing, flanging,
doubling, chorusing, and echo. The chorusing feature operates by generating extra notes which can be successively detuned,
delayed and/or decayed.
You can define one set of Chorus parameters for each Program. Whether or not these Chorus parameters are active for any
individual layer in that program is controlled by the Chorus Enable switch for each layer which can be set to Off, Fixed, M-
Wheel, or K-Press (the default is Off). To fully understand the capabilities of Chorus mode, see the description of the various
chorus enabling options in Layer Editing.
The Chorus parameters being modified are those for the currently active program. In order to hear the effects of your Chorus
editing, turn on one of the active modes (Fixed, K-Press, or M-Wheel) of the Chorus Enable switch for the layer or layers you
want to add Chorus to (see Layer Editing).
Using the Chorus Editor
Select CHORUS editing by pressing EDIT INCR (The word CHORUS is printed above the key on the button-pad).
The parameters shown in Table 9-1 (on the following page) can be edited. One will appear in the display; the others can be
selected by using NEXT and PREV.

What it Does
.X-NOTES
Extra Notes
0-7
Selects the number of extra notes to be played.
.DTUNE
Detune
±0-6,000C
Varies the pitch of the successive notes.
.DELAY
Delay
0-4000ms
Delays each successive note by the given time interval.
.DECAY
Decay
0-12dB
Reduces the volume of each successive note.
* You can also enter the value directly with the right button-pad and press ENTR.
See the sections on each parameter later in this chapter.
The Chorusing parameters work in conjunction with each other. For instance, until audibly perceptible values are set for
Detune and Delay, selecting multiple notes will not sound dramatically different; it will just "fatten" up the sound of the
original note. Likewise, selecting 3 Notes and a Delay of 200 ms, with no detuning, will only repeat the original sound 3
times, 200 ms apart.
Remember that you can interactively listen to your modifications to the Chorus editor. To do this, at least one layer in the
region of the keyboard that you’re playing must have its Chorus Enable switch on (see Layer Editing). When you select
values using the numeric button pad and press ENTR or change values using INCR and DECR, the changes in sound can be
heard by playing the keyboard. Also note that you can press UNDO to toggle between the current value and the previous
value, or CLR to reset a value to 0.
Notes
When the display shows .X-NOTES, you can select the number of extra notes to sound. Enter the value directly with the
numeric button-pad and press ENTR or use INCR and DECR to add or subtract one note at a time.
Up to 7 notes can be selected. If you enter a value greater than 7 using the numeric button-pad, the number of notes will be
set to 7 when ENTR is pressed.
