Virtual Synthesizer VST VST3 Audio Unit
Synth Leads, Pads, Basses,
Keys, Atmos and Sound
Synthelium is a virtual instrument inspired by
the classic synthesizers of the 70s and 80s.
Features a wide collection of 50 tones emulated of
synth leads, pads, keys, basses, atmos and effects sounds
to create electronic, rock, metal, smooth jazz, pop,
hip hop, trance, EDM, and new age music, among
others. The pads and atmos
presets also makes it suitable for soundscapes and
cinematic, as well as ambient and atmospheric
textures. Sounds can be modulated with filter
section, envelope generator and effects to give a
vast array of custom sounds.

• Tremolo Section: The low-frequency oscillator knobs apply 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. Enabling 'Destination'
by selecting 'Panning' mode applies a rhythmic variation in amplitude in the
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:
ØWaveForm: Switches between
‘Triangle’, ‘Sine’, ‘Saw’, ‘Square’ and ‘Exponential’ waveforms.
ØSource: Switches between ‘Modulation
Wheel’, ‘Aftertouch’ and ‘Velocity’. ØDestination: Switches between
‘Pitch’, ‘Expression’ and ‘Pan’ modulation.
ADSR envelope generator with Attack, Sustain, Decay and Release parameters:
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
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:
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 Parameters: It controls the loudness, the way in which we
perceive amplitude.The sensitivity level is set by the user:
• 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.
auralization: Synthesizer emulations brings a stereophonic sound panning to increase the
audible perspective, even without using the built-in reverberation or LFO
• MIDI CC Automation: Implementation of MIDI Continuous Controller
parameters for use with external hardware control via DAW, such as: LFO
depth (CC#1), expression (CC#11), volume (CC#7),
pan (CC#10), balance (CC#8), filter cutoff (CC#74), ADSR (Attack: CC#73,
Decay: CC#75, Sustain: CC#76, Release: CC#72) and reverb depth (CC#91).
