• 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.

Ø Rate: 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.

The following combo boxes settings adds motion or variability to sounds:

Ø WaveForm: Switches between ‘Triangle’, ‘Sine’, ‘Saw’, ‘Square’ and ‘Exponential’ waveforms.
Ø Source: Switches between ‘Modulation Wheel’, ‘Aftertouch’ and ‘Velocity’.
Ø Destination: Switches between ‘Pitch’, ‘Expression’ and ‘Pan’ modulation.

• ADSR envelope generator with Attack, Sustain, Decay and Release parameters:

Ø Attack determines the time it takes for the note to get to the 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 of the sound is played at while the note is held (after the other envelope states, Attack and Decay, have been completed).
Ø Release determines the time it takes for the note to fall from the sustain level to zero (silence) level when it is released.

• Pitch Bend: The Pitch Bend knob directly changes the pitch of the selected instrument.

Ø Pitch 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 the right.

• 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:

Ø Low 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 pass filters.

• Amplitude Range Parameters: It controls the loudness, the way in which we perceive amplitude.The sensitivity level is set by the user:

Ø Amplitude range (low) - sets amplitude range, lower bound (dB) 
Ø Amplitude range (high) - sets amplitude range, upper bound (dB)

• Volume: Adjusts the volume of the instrument.

• Panning potentiometer control: Set the panning of the instrument. Adjusts the stereo pan position of the signal output, which determines how much of signal is sent to the left and right channels.
