FILTER · DEVICE LABBEGINNER MODE
Auto Filter
A sweeping filter that wahs and wobbles.
WHAT IT DOES
A filter removes frequencies above or below a point called the cutoff. RESONANCE makes the cutoff sing — that's the classic wah and acid sound.
HOW IT WORKS
Move the CUTOFF up to brighten, down to muffle. RESONANCE adds emphasis. The LFO sweeps the cutoff back and forth on its own.
