🌀 Built-In Effects

The effects on the DJM-S9 are split into two major groups: Beat FX (onboard Pioneer effects) and Sound Color FX (filter-like color effects). You can also trigger Serato DJ FX from the mixer. Pioneer DJ

🥁 Beat FX — 15 Built-In Effects

These are onboard Pioneer DSP effects you can apply directly from the mixer:

1. Back Spin
2. Delay
3. Echo
4. Fader Synth (Saw)
5. Fader Synth (Sine)
6. Fader Synth (Square)
7. Flanger
8. HP Filter (High-Pass)
9. LP Filter (Low-Pass)
10. Phaser
11. Reverb
12. Roll
13. Spiral
14. Trans
15. Vinyl Brake

➡️ These effects let you shape transitions and textures, from rhythmic delays to filter sweeps and vinyl-style brakes. The fader synth types modulate the audio with synth-like timbres based on the mixer’s fader movement. Pioneer DJ

🎨 Sound Color FX — 5 Core Color/Filter Effects

These are the classic DJM color effects that function similarly to a performance filter section, but with character and modulation options:

1. Dub Echo – A ping-pong-style delay with groove emphasis
2. Filter – High or low pass filter sweep (cutoff modulation)
3. Noise – Noise layer blended into the signal
4. Pitch – Pitch shift style modulation
5. Wide Filter – A broader filter with larger sweep range

👉 The Filter knob acts as a high/low pass filter: turning it counterclockwise lowers the cutoff (more bass), clockwise raises the cutoff (more treble). Pioneer DJ+1

🔗 Serato DJ FX (iZotope-Powered)

When used with Serato DJ Pro, the DJM-S9’s FX section can control a vast library of Serato DJ FX, typically up to ~55 effects depending on your expansion packs. These include:

• Echo variations
• Pitch, Gate, Crush
• Noise, Reverb types
• Flanger, Phaser
• Filter mods like Dub Echo & Noise
• And many more producer/serato-specific effects

The effects can be triggered from the mixer and mapped to the paddles and knobs, letting you change effects, toggle them on/off, and adjust parameters all from the hardware. Solotech+1

🎚️ Filters & Additional FX Control

In addition to the Sound Color FX and Beat FX:

• Each channel has a dedicated filter knob for instant high- or low-pass filtering. Pioneer DJ
• Filters can be used independently or layered with Beat FX and Serato FX.
• Some Serato FX (via software) include Dub Echo, Noise, Pitch filters and more complex variations. Solotech
