• The harmonica (known as the French harp or mouth
organ) comes in two modes:
natural and vibrato,
and is used in many musical genres, especially blues,
American folk music, classical music, jazz, country, and
rock and roll.
ADSR envelope generator with Attack, Sustain, Decay and Release parameters:
determines the time it takes for the note to reach its maximum
level. Ø Decay
determines the time it takes for the note to go from the maximum level
to the sustain level (controlled by Sustain). Ø Sustain
determines the level at which the sound is played while the note
is held (after the other envelope states, Attack and Decay have
passed). Ø Release
determines the amount of time it takes for the note to fall from
the sustain level to zero (silence) when released.
• Pitch Bend: The Pitch Bend knob directly changes the pitch of the selected
Bend center position: is normal pitch. Ø Pitch
Bend down: Specifies the amount of pitch change that will occur when the
pitch bend/modulation lever is moved to the left. Ø Pitch
Bend up: Specifies the amount of pitch change that will occur when the
pitch bend/modulation lever is moved to the right.
• Low-Frequency Oscillator Controls: These knobs apply LFO modulation to the
selected instrument. By using the LFO to modulate various aspects of the
audio signal, you can apply effects such as vibrato or tremolo.
This knob controls the frequency. Turn clockwise for a faster
modulation rate. Ø Depth:
This knob controls the amplitude. With a lower setting, the
resulting modulation is subtle, while a higher depth will result
in a much more extreme effect.
• Reverb built-in: provides a spaciousness and depth to simulate the
sound reflections from walls, floors and ceilings following a sound created
in an acoustically reflective environment. Small rooms can be modeled as
well as large spaces.
• Filter Type. Combo box to switch between the following options:
Pass (LPF): a filter that passes signals with a frequency lower than a
certain cutoff frequency and attenuates signals with frequencies higher
than the cutoff frequency. Ø High
Pass (HPF): a filter that passes signals with a frequency higher than a
certain cutoff frequency and attenuates signals with frequencies lower
than the cutoff frequency. Ø None:
No filter is applied. Ø Cutoff
Frequency Filter: Sets the cutoff frequency for the low pass and high
• Amplitude Range parameter: It controls the loudness, the way in which we
perceive amplitude. The sensitivity level is set by the user:
• Volume: Controls the volume of the virtual instrument.
• Panning potentiometer control: Set the panning of the instrument. Adjusts
the stereo pan position of the signal output, which determines how much of
the signal is sent to the left and right channels.
With Akkordica you can choose from a wide
range of accordion, concertina, bandoneon, harmonica and
melodica sounds, playing and feeling the traditional sounds
as well as the built-in effects for the digital age.
