Oscillator — Your Raw Sound Source
Every synth starts here. The oscillator generates the basic waveform that forms your sound. Change the shape and you change the timbre — the character of the tone before any shaping.
Play the keyboard below. Then try switching between Sine (pure), Saw (bright, buzzy), Square (hollow, woody), and Triangle (soft, flute-like).

Filter — Shaping Your Sound
The filter removes or emphasizes frequencies from your raw sound. Cutoff sets the frequency it acts on. Resonance creates a peak right at that point, giving that classic synth "sweep" sound.
Try playing a note, then drag Cutoff slowly to hear the sound open and close.

Envelope — Shaping Over Time
The ADSR envelope shapes how a note evolves: Attack (time to peak), Decay (time to sustain), Sustain (held level), Release (fade out). It's what makes a synth pluck, pad, or punch.
Play a long note and adjust Attack — you'll hear it take time to reach full volume.

LFO — Making Sound Move
An LFO (Low Frequency Oscillator) is an oscillator too slow to hear, used to modulate other parameters. Route it to pitch for vibrato, filter for wobble, or volume for tremolo.
Enable the LFO, set rate to about 5 Hz, and route it to Pitch — you'll hear a gentle vibrato.

Effects — Polishing Your Sound
Effects add depth and space. Reverb simulates a room. Delay creates echoes. These turn a dry synth tone into a full, immersive sound.
Play a note and turn up Reverb — you'll hear the sound linger and blend into a space.
