Signature Sounds

The 808 snare combines two pitched tones with a noise burst. The tones provide body, the noise provides snap. The 'snappy' control adjusts noise amount.

808 hi-hats are metallic noise. Six square wave oscillators at non-harmonic intervals create complex metallic tone, then filtered and gated. Closed hat = short gate, open hat = longer gate.

The 808 clap is multiple noise bursts with built-in reverb. Creates the illusion of many hands clapping together. The spread of the initial hits creates the 'flam' effect.

The 303's 18dB/octave diode ladder filter has a unique squelchy character. High resonance creates the acid 'wah' sound. The envelope amount controls how much the filter opens on each note.

Accent is the 303's secret weapon. Accented notes are louder AND have increased filter envelope depth. This creates the rhythmic variation that makes acid patterns come alive.

Slide makes the pitch glide smoothly from one note to the next instead of jumping. Combined with accent, creates the liquid, rubbery quality of classic acid bass.

The 24dB/octave ladder filter is THE Moog sound. It has a warm, musical quality even when driven hard. The emphasis (resonance) is smooth rather than aggressive.

The Moog bass sound that defined funk, prog rock, and countless genres. Three oscillators, slight detuning, filter envelope for growl.

Screaming Moog leads cut through any mix. Square waves, open filter, portamento (glide) for expression.

Punchy, snappy bass with that characteristic 80s FM twang. Fast decay envelope on modulator creates the 'slap' transient.

Non-integer ratios between operators create inharmonic, metallic bell tones. The DX7 made bells that sample libraries still try to match.

The DX7 has 32 fixed algorithms—ways to connect the 6 operators. Operators on top modulate operators below. Carriers (bottom) are heard, modulators (top) affect timbre.

Polyphonic brass stabs that defined 80s pop. Fast filter envelope attack, resonance for honk.

Poly-Mod uses Osc B and the filter envelope as modulation sources. Route them to Osc A frequency or pulse width, or filter cutoff. Creates animation and FM-like effects.

Stack all 5 voices on one note for massive mono leads. All oscillators slightly detuned = huge, fat sound. The unison mode that launched a thousand patches.

The sound of synthwave and retrowave. Saw wave, gentle filter, slow attack, chorus I+II. Simple recipe, iconic result.

Punchy, warm bass with the sub-oscillator adding weight. Keep chorus subtle or off for bass to maintain focus.

While not as complex as real strings, Juno creates beautiful string-like pads. PWM adds movement without the chorus doing all the work.

Ben Burtt created R2-D2's voice on an ARP 2600. Random LFO to pitch, filter sweeps, and the performer's real-time manipulation brought the droid to life.

The 2600's filter has its own character—slightly different from Moog but equally fat. Great for growling, aggressive bass.

Everything is pre-connected but patchable. Insert a cable to override. This makes it immediately playable but infinitely tweakable.

Dexed is a free, open-source DX7 clone that loads original DX7 patches. Perfect for learning FM synthesis. All 32 algorithms, 6 operators, exact recreation.

Any wavetable synth can create an 808. Use a sine wave, add a pitch envelope, done. The principles are the same as the original hardware.

Vital can create convincing acid bass. Saw oscillator, resonant filter, filter envelope, add accent and slide in your sequencer.
