Flashcards
0/20
Filter Cutoff Frequency
Adjusts the frequency at which the filter starts to attenuate frequencies above (low-pass) or below (high-pass) it.
Amplitude Modulation
Varies the volume with another oscillator to create tremolo effects or more complex timbres.
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.
Attack Time
The time taken for the initial increase from zero amplitude to peak amplitude after a note is played.
Sustain Level
The amplitude level during the main sequence of the sound, after decay and until release is triggered.
Pulse Width (PWM)
Adjusts the duty cycle of a square wave, affecting the harmonic content and timbre of the sound.
LFO Rate
Controls the speed at which the Low Frequency Oscillator modulates another parameter, like pitch or filter cutoff.
Envelope Generator
Shapes the amplitude or other parameters over time with stages like Attack, Decay, Sustain, and Release.
LFO Depth
Determines the amount of modulation applied to a parameter by the Low Frequency Oscillator.
Noise Generator
Produces white, pink, or other types of noise for percussive sounds or to add texture.
Oscillator Detune
Slightly shifts the pitch of an oscillator relative to others to create a thicker, chorused sound.
Ring Modulation
Mixes two oscillators in a way that creates new, often inharmonic, frequencies.
Oscillator Waveform
Determines the timbre by shaping the sound wave; options include sine, square, sawtooth, and triangle waves.
Decay Time
The time taken for the sound to fall from the attack peak to the sustain level.
Portamento/Glide
The time it takes for a pitch to glide from one note to the next, creating a smooth transition effect.
Resonance
Emphasizes frequencies around the cutoff point, which can add a 'ringing' or 'whistling' sound.
Frequency Modulation
Uses the frequency of one oscillator to modulate another, creating complex harmonic content.
Release Time
The time taken for the sound to decay to zero after the key is released.
Polyphony
Determines the number of notes that can be played simultaneously on a synthesizer.
