Oscillator: The SFO Uses the raw samples in a soundfont file (*.SF2) as waveforms. Samples can be arranged into Banks, Patches, Key and Velocity zones.
2 Digitally Controlled Oscillator - DCO - with 3 selectable waveforms (Saw, Triangle, Pulse) have knobs to control the octave (4' 8' 16') , and interval.
2 Digitally Controlled Filter - DCF - A) with control over cutoff, contour amount, FM mod and emphasis. B) with control over ADSR envelope generator (Attack, Decay, Sustain, Release).
Oscillators A & B, master volume, Filter mod and Tracking rate.
LFO (Low Frequency Oscillator) with 2 selectable waveforms (Triangle & Pulse)
Loudness Contour with control over ADSR (Attack, Decay, Sustain, Release).
(Waveshaper): A wave distortion effect which maps input to output values using flexible spline-based graph. Distorts the input depending on a transfer function you draw by dragging the control points with your mouse.
(Glide) Control: affects pitch transitions. A gliding effect that allows a sound to change pitch at a gradual rate, rather than abruptly, when a new key is pressed or MIDI note sent. When turned to the far left, there are no pitch transitions - new notes immediately play at their "correct" pitch. If turned to the right, the glide time increases - new notes are triggered at the pitch of the previous note, and then gradually glide to the pitch of the played note, quickly or slowly, depending on the setting of this knob.
Delay Effect Built-in: with Modulation (Varies the delay time dynamically- 0 to 10V ) and Amount of Feedback controls.
On-screen MIDI keyboard that can be played with the mouse, or keyboard (Q is Middle-C, Z two Octaves lower) The 'T' on the left of the keyboard sets Toggle Mode where each key stays held until you click it a second time.
76 internal presets (Pre-programmed sounds).
Possibility of turn the
Synth into Mono Mode and Retrigger switch.
Property: Tool tip when the mouse is over a control. You can mouse over any of the controls anywhere in Zephyrus and this will display a short description of what that control does.
One-panel Graphical User Interface
MIDI Automation: Complete MIDI Continuous Controller (Control of all
parameters for use with external hardware control). The following 23 MIDI
