VirtualDJ - VDJ 2026 FX + parameters (database) (de)

Hi fellow DJs

Yes — but on VirtualDJ forums, the only reliable way to get real bullet points is still the BBCode list tag. What you can do (so you don’t see the “

” style and you just see bullets) is to use plain text bullets and avoid [list] entirely.

Here’s the same post format using plain bullets • (no [list], no

[*], no brackets):

VirtualDJ FX quick reference: key parameters (from UI screenshots)

I’m building a community reference list of FX and their key UI parameters so scripting/programming is faster.
Important: the numeric values shown in screenshots are NOT “the correct values” — they’re just examples. What matters is the parameter name + slider index + unit (%, bt, Hz, dB, on/off, etc.).

Notes
• Beat unit is bt (beats).
• Selectors (Pattern/Mode/Scale/etc.) often don’t show all options in the UI, so the full option list/range may be unknown here.
• Known signed ranges (confirmed/visible):
• Filter Position: -20 Hz → 15000 Hz
• Stems bands: -100% → +100%
• Typical scripting pattern (example):

effect_active ‘Echo’ on & effect_slider ‘Echo’ 1 50% & effect_slider ‘Echo’ 2 1bt
