4. Turntable scratch FX
You can make turntable scratch-style sounds in Serum’s Noise oscillator. Select an analogue noise sample ( ARP Circuit works well), and ensure loop mode is enabled, so you have a constant output. Head over to an LFO and make yourself a gnarly custom shape with some aggressive, jagged curves. Now assign this LFO to modulate the Phase knob of the Noise oscillator, and tweak the modulation amount and Phase level to suit. DJ Shadow, eat your heart out!
