Detailed Editing with Programs
You can create original sounds by editing a preloaded
program or by editing an initialized program.
For details, please see “Saving your edits” on page 28.
Before you start editing
The three elements of sound: pitch, tone,
and volume
Sound is made up of three basic elements: pitch, tone, and
volume.
The KROSS provides “pitch,” “filter,” and “amp
(amplifier)” sections that allow you to control these
elements.
The “pitch” section modifies the pitch, the “filter” section
modifies the tone, and the “amp” section modifies the
volume.
Pitch settings are made in the P-PITCH and P-PITCH EG
pages; filter settings are made in the P-FILTER and P-
FILTER EG pages; amp settings are made in the P-AMP and
P-AMP EG pages.
EG, LFO, AMS, and controllers
In addition to the three elements listed above, a sound can
vary according to the passage of time, the pitch range in
which it’s played, or by performance expressions.
Such aspects can be controlled by modulators and
controllers such as the EG (envelope generator), LFO (low
frequency oscillator), and the modulation wheel. These
modulators and controllers can apply changes to the basic
program.
Take a look at the illustration below called “Program
structure.” Notice that the signal flow is in the order of
Oscillator/Pitch, Filter, Amp. You can see how the EGs and
LFOs affect each section.
As shown in the illustration, each program consists of
sections such as OSC 1/2, effects, and the arpeggiator.
OSC (oscillator) 1/2
The OSC (oscillator) generates the waveform that is the
basis of the sound. On the KROSS, the oscillator consists of
multiple sampled sounds, such as a multisample or a drum
kit (drumsamples).
The KROSS provides two oscillators; OSC1 and OSC2. You
can create more complex programs by combining these.
The OSC, which is the basis of the sound, can be controlled
by modulating its pitch, filter, amp, EG, and LFO to change
the sound in a wide range of ways.
Note: Pitch EG is shared by OSC1 and OSC2.
Effects
As effects, you can use five insert effects, and two master
effects.
The output of OSC 1/2 is sent to these effect processors. By
choosing the desired effect for each processor and editing its
parameters, you can apply a wide range of effects such as
modulation, distortion, and reverberation.
Arpeggiator
A program can use one arpeggiator. You can select an
arpeggio pattern, specify the range that the pattern will be
developed within, and specify the range of notes or
velocities that will trigger the arpeggiator.
Drum Track and step sequencer
While the arpeggiator plays the main program, separate
drum programs are provided for the Drum Track and the step
sequencer.
The Drum Track lets you select a drum program and pattern,
and specify how it will be triggered.
The step sequencer lets you select the instrument that the
drum program will use, and lets you specify a pattern by
using buttons 1–16.
