Drum Synthesis in Vital
Crafting a Full Drum Kit in Vital Synth⌗
1. Kick Drum⌗
A kick drum should have a deep thump with a quick, punchy impact.
- Oscillator: Set Oscillator 1 to a sine wave around 50-60 Hz to give the kick a solid low end.
- Pitch Envelope: Add a quick pitch modulation envelope to simulate the “thump.” Start from a slightly higher pitch and drop rapidly to the base frequency.
- Attack: Instant (0 ms).
- Decay: Short (30-50 ms) for a quick drop.
- Amplitude Envelope:
- Attack: Instant (0 ms).
- Decay: Short to medium (around 100 ms).
- Sustain: Zero for a punchy cutoff.
- Release: Short (30-50 ms) to ensure it doesn’t linger.
- Distortion (Optional): Apply a touch of distortion for extra grit.
2. Snare Drum⌗
The snare drum combines a tonal “body” and a noisy “rattle” to create that signature snare sound.
- Oscillator 1: Use a sine or triangle wave set around 150-200 Hz for the body.
- Noise Oscillator: Activate a noise oscillator to emulate the snare’s “rattle.” Use white or pink noise.
- Filter: Apply a highpass filter to the noise oscillator to focus it in the midrange (2-8 kHz).
- Amplitude Envelope (Tonal Layer):
- Attack: Instant (0 ms).
- Decay: Short (100-150 ms).
- Sustain: Zero.
- Release: Short (50 ms).
- Amplitude Envelope (Noise Layer):
- Attack: Instant.
- Decay: Medium (150-250 ms).
- Sustain: Zero.
- Release: Short (50 ms) for a clean fade.
- Reverb (Optional): Add a slight reverb to the noise layer for a realistic snare ambiance.
3. Hi-Hats (Closed and Open)⌗
Hi-hats are sharp and metallic, primarily driven by noise.
- Noise Oscillator: Set this oscillator to white noise to emulate the crispness of hi-hats.
- Filter: Use a bandpass filter around 4-10 kHz with slight resonance to focus on the metallic frequencies.
- Amplitude Envelope (Closed Hi-Hat):
- Attack: Instant.
- Decay: Very short (20-50 ms).
- Sustain: Zero for a tight, quick cutoff.
- Amplitude Envelope (Open Hi-Hat):
- Attack: Instant.
- Decay: Longer (150-200 ms) to let it ring out.
- Sustain: Low for a sustained effect.
- Release: Short (50 ms).
- Reverb (Optional): Add a small amount of reverb to the open hi-hat for depth.
4. Toms (Low, Mid, and High)⌗
Toms require a tonal, resonant sound with a slight pitch modulation.
- Oscillator: Use a sine wave at different pitches for each tom:
- Low Tom: 100 Hz
- Mid Tom: 200 Hz
- High Tom: 300-400 Hz
- Pitch Envelope: Use a fast-decaying pitch modulation envelope to add impact.
- Attack: Instant.
- Decay: Very short (20-30 ms) for a quick drop.
- Amplitude Envelope:
- Attack: Instant.
- Decay: Medium (150 ms).
- Sustain: Zero for a clean cutoff.
- Release: Short (50 ms).
- Filter (Optional): Apply a lowpass filter to roll off highs, giving the toms a rounded tone.
5. Clap⌗
A clap sound is essentially a burst of noise with a staggered decay that mimics the sound of multiple hands clapping.
- Noise Oscillator: Use white noise to simulate the “slap.”
- Filter: Apply a highpass filter to remove low frequencies and focus on the mid-high range (2-5 kHz).
- Amplitude Envelope:
- Attack: Instant.
- Decay: Use a staggered decay with several peaks and drops to mimic layered claps.
- Sustain: Zero.
- Release: Short to avoid excessive ringing.
- Reverb (Optional): Add a slight reverb for an ambient effect.
6. Rim Shot⌗
A rim shot has a quick, bright attack with a woody resonance.
- Oscillator 1: Set to triangle or square wave at a high pitch (1-2 kHz).
- Noise Oscillator: Add a bit of filtered noise for extra sharpness.
- Filter: Use a highpass filter to focus the sound on mid-high frequencies.
- Amplitude Envelope:
- Attack: Instant.
- Decay: Short (around 50-100 ms) for a clean sound.
- Sustain: Zero.
- Release: Short.
- Optional Reverb: Use minimal reverb to avoid washing out the sound.
7. Cowbell⌗
A cowbell has a metallic, resonant sound with a longer decay.
- Oscillators: Use two sine waves to create metallic overtones:
- Oscillator 1: Set to around 400-600 Hz.
- Oscillator 2: An octave or a fifth above (800-1200 Hz) for metallic resonance.
- Amplitude Envelope:
- Attack: Instant.
- Decay: Medium (100-150 ms) for resonance.
- Sustain: Zero.
- Release: Short to avoid excessive ring.
- Bandpass Filter: Use a bandpass filter to focus on the mid frequencies and add resonance for metallic character.
