Oscillator Waveform
Determines the timbre by shaping the sound wave; options include sine, square, sawtooth, and triangle waves.
Filter Cutoff Frequency
Adjusts the frequency at which the filter starts to attenuate frequencies above (low-pass) or below (high-pass) it.
Resonance
Emphasizes frequencies around the cutoff point, which can add a 'ringing' or 'whistling' sound.
Envelope Generator
Shapes the amplitude or other parameters over time with stages like Attack, Decay, Sustain, and Release.
Attack Time
The time taken for the initial increase from zero amplitude to peak amplitude after a note is played.
Decay Time
The time taken for the sound to fall from the attack peak to the sustain level.
Sustain Level
The amplitude level during the main sequence of the sound, after decay and until release is triggered.
Release Time
The time taken for the sound to decay to zero after the key is released.
LFO Rate
Controls the speed at which the Low Frequency Oscillator modulates another parameter, like pitch or filter cutoff.
LFO Depth
Determines the amount of modulation applied to a parameter by the Low Frequency Oscillator.
Oscillator Detune
Slightly shifts the pitch of an oscillator relative to others to create a thicker, chorused sound.
Portamento/Glide
The time it takes for a pitch to glide from one note to the next, creating a smooth transition effect.
Amplitude Modulation
Varies the volume with another oscillator to create tremolo effects or more complex timbres.
Frequency Modulation
Uses the frequency of one oscillator to modulate another, creating complex harmonic content.
Noise Generator
Produces white, pink, or other types of noise for percussive sounds or to add texture.
Pulse Width (PWM)
Adjusts the duty cycle of a square wave, affecting the harmonic content and timbre of the sound.
Ring Modulation
Mixes two oscillators in a way that creates new, often inharmonic, frequencies.
Polyphony
Determines the number of notes that can be played simultaneously on a synthesizer.
Velocity Sensitivity
Allows the strength with which a key is pressed to influence the sound's volume or other parameters.
Arpeggiator
Automatically steps through a sequence of notes, usually derived from a chord, to create rhythmic patterns.
