PerformFX

PerformFX is Meiji Sampler’s dedicated live-effects surface.

​
Where it lives

Open the Perform tab by pressing Tab from the Create screen.

​
What it does

PerformFX lets you trigger curated live effects from assigned keys rather than manually adjusting mixer controls in real time.

​
Core controls

  • b toggles bank
  • q cycles quantize mode
  • e opens the binding editor
  • k kills all active effects

​
Preset categories

The built-in preset library is organized into categories such as:
  • SP-style
  • DJ FX
  • Time
  • Space
  • Utility

​
Example preset types

The built-in library includes effects such as:
  • beat repeat
  • rhythmic gate
  • HPF / LPF sweeps
  • dub siren
  • echo delay
  • flanger
  • halftime
  • hype button
  • motor kill
  • reverb
  • tape stop
  • vinyl sim
  • volume duck
The HPF and LPF sweep effects use the same 6th-order Butterworth biquad engine as the mixer channel filters, with optional resonance that adds a musical peak at the cutoff frequency. This makes filter sweeps sound clean and defined rather than gradual.

​
Why use PerformFX instead of manual mixing

PerformFX is for momentary performance gestures. The mixer is for stable mix decisions.
