Using The Amp Section - Korg Krome Operation Manual

Playing and editing Programs

Using the Amp section

The Amp section includes controls for volume, pan,
and the driver circuit.
You can control the volume using the Amp EG, LFO 1/
2, Key Track, and velocity, along with other AMS
sources.
Each Oscillator has its own Amp section: Amp1 for
OSC1, and Amp2 for OSC2.
Background - what does "Amp"
mean?
Different sounds have characteristic shapes to their
volume levels.
For example, the volume of a piano note begins at a
high volume the instant you play the note, and then
decreases gradually.
The volume of an organ note, on the other hand,
remains constant as long as you continue pressing the
key.
The volume of a note on a violin or wind instrument
can be varied during the note by the musician (i.e., by
regulating the amount of pressure on the bow or the
force of the breath).
Volume Piano
Volume decays
gradually
Pan
Pan
The main Pan parameter controls the stereo position
after the signal has passed through the oscillator, filter,
and amp.
Normally you'll set this to C064, so that the sound is
centered equally between the left and right speakers.
To create a stereo effect when Oscillator Mode is set to
Double, set the Amp1/Driver 1 page Pan to L001, and
the Amp2/Driver2 page Pan R127. This will make
OSC1 go to the left speaker, and OSC2 go to the right
speaker.
With a setting of Random, the pan will change
randomly each time you play a note on KROME,
producing an interesting effect.

Pan - Use DKit Setting
Use DKit Setting applies when Oscillator Mode is set
to Drums or Double Drums.
If this is checked, the Program can use a different pan
position for each drum sound, as specified by the
Drum Kit. If this is unchecked, all drum sounds will
use the Program's pan position.
The factory presets and GM drum kits use individual
pan positions for the different drums, so normally it's
best to leave this checked.
Amp modulation
The basic volume level is set by the Amp Level
parameter. You can then alter this using the
modulation sources below:
Keyboard Track
This lets you vary the volume relative to the note you
play.
Time
For details, please see "Keyboard Track" on page 39.
Amp Modulation
Velocity Intensity is used by most programs to
decrease the volume of softly played notes and
increase the volume of strongly played notes, and the
Amp Modulation parameter adjusts the depth of this
control.
Normally you will set Amp Modulation to positive (+)
values. As this setting is increased, there will be
greater volume difference between softly played and
strongly played notes.
LFO1/2
Specifies how the LFO's will produce cyclic changes in
volume (tremolo effect).
The volume will be affected by the LFO(s) where you
set an LFO1 Intensity, LFO2 Intensity value.
Intensity (AMS Intensity) adjusts the depth of how the
tremolo effect produced by the LFO will be affected
when you assign an AMS (LFO1 AMS, LFO2 AMS).
For example, if you set AMS to JS‐Y: CC #02, tremolo
will be applied when you push the KROME's joystick
down (toward yourself), or when CC#02 is received.
