1. About the effects
As effects, the microKORG XL+ provides a two-band EQ and two master
effects. You can use the EQ to modify the sound of each timbre, and use
the master effects to apply spatial-type processing to the overall sound.
For each master effect you can choose one of seventeen full-digital effects,
which are categorized as follows.
Filter and dynamics effects such as EQ and compressor
Pitch and phase modulation effects such as chorus and phaser
About the effect input and output
The master effects are stereo-in and stereo-out. In the "DRY/WET" bal-
ance, the stereo-input DRY signal (the sound not processed by the effect)
is passed through to stereo-output. The way in which the WET signal (the
sound processed by the effect) is output will depend on the type of effect,
with the following variations.
Mono In - Mono Out
Mono In - Stereo Out
Stereo In - Stereo Out
The input/output variation for each effect is shown in the upper left of the
To obtain the best sound quality, you should adjust the input level to the
master effect as high as possible without causing clipping. This is done
using the AMP "LEVEL" parameter, the MIXER "OSC1 LVL," "OSC2 LVL,"
and "NOISE.LVL" parameters, and the "TRIM" parameter of each effect.
Controlling effect parameters
Effect knob assignments
Then use each effect's "DRY/WET" or "OUT.LEVEL" parameters to adjust
the output level of the effect.
Some effect types do not have a "TRIM" or "OUT.LEVEL" parameter.
There is no input level meter etc. to check the input level to the
effect. Insufficient input level will produce a poor S/N ratio, while
excessive input level will cause clipping.
You can use the front panel knobs , , and  to control effect parame-
ters in realtime. The parameters assigned to knobs can also be controlled
from an external MIDI device.
When the [KNOB FUNCTION SELECT] dial is set to EFFECT or ASSIGN,
you can use the performance edit function ( p. 16) to control the parame-
ters assigned to [CTRL-1] and [CTRL-2] for each effect MST FX1 and MST
Immediately after you've selected an effect, the most useful two parameters
of that effect will be automatically selected for [CTRL-1] and [CTRL-2]. If
you want to control other effect parameters rather than these, you can
assign those effect parameters to [CTRL-1] and [CTRL-2].
For details, refer to the section about performance editing control ( p. 16),
and the section about the knobs ( p. 33).
Noise may occur if a parameter that cannot be assigned to a knob is
operated while sound is being produced.
The DRY/WET settings of MST FX 1 and MST FX 2 are handled sepa-
rately from the other effect parameters. If you assign MST FX 1 or MST
FX 2 DRY/WET to a knob when the [KNOB FUNCTION SELECT] dial is
set to ASSIGN, the above parameter will be assigned to the knob
( p. 33 "KNOB").
For details on the parameters that can be assigned to knobs, refer to
page 65 "2.Effect Parameters".
