This acid 303 arpeggio features a classic sawtooth oscillator playing a 16-step sequence repeated over 4 bars at 140 BPM in the key of D#. The pattern includes pitch slides gliding smoothly between notes ranging from 77.78 Hz (D#2) to 155.56 Hz (D#3), with accented steps triggering a higher filter cutoff (up to 3500 Hz) and louder volume. Each note passes through a 4-pole low-pass filter with a decaying cutoff envelope and is saturated with tanh distortion to add bite and harmonic richness. The final output is stereo, normalized, and cleaned with a high-pass filter to remove low-end mud.
This arpeggio suits acid house, techno, and other electronic genres around 140 BPM. It works well as a driving melodic sequence or rhythmic filler. Layering with sub bass or reverb can add depth, but watch for potential frequency masking in the midrange due to the prominent filter and distortion character.
