electro synth sweep

About this sample

This sound features a 4-second stereo sweep built from two detuned sawtooth waves and a square sub-oscillator with a 30% duty cycle, all centered around a low A (55 Hz). A subtle white noise layer adds texture, feeding a resonant 4-pole low-pass filter that logarithmically sweeps its cutoff frequency from 80 Hz to 16 kHz. The filtered signal is shaped by a slow attack and release amplitude envelope, then saturated with tanh distortion for warmth and grit. The final output is normalized to -3 dB for a balanced level.

It suits electronic genres like electro and synthwave, especially at moderate tempos where a 4-second FX fits naturally. Use it to add movement or tension in transitions, layering with pads or bass for depth. Watch for its low-frequency energy in mixes to avoid muddiness, and consider additional EQ or sidechain compression if needed.
