Imperfector

Artur Stereo

Where to get itAvailable from Artur Stereoreasonstudios.com

It combines strum delay, random delay, LFO modulation, and velocity processing to add nuance and groove to quantized chords and programmed parts. Part arpeggiator, part humanizer, part strum engine, Imperfector works with any instrument and sound source to make programmed MIDI feel played rather than quantized.

Key Features

01Strum Delay with ascending/descending pitch-based note ordering (0–508 ms or tempo-synced)
02Random Delay with Per Group Mode and Per Note Mode for organic timing variation
03LFO modulation with sine and triangle waveforms (0–10 Hz or tempo-synced) and phase inversion
04Three-stage velocity processing: Velocity Scaling, Velocity Direction, and Velocity Randomization (0–127)
05Free and Sync tempo modes for all delay parameters (1/64 notes to whole notes)
0610 factory patches ranging from subtle humanization to extreme rhythmic effects
07Full automation, MIDI CC mapping, and Player On/Off bypass

Things to Try

  • 01Use Strum Delay in ascending mode for piano chord spreads or descending mode for guitar-style strums
  • 02Apply Random Delay in Per Group Mode for natural, cohesive humanization or Per Note Mode for loose, experimental textures
  • 03Modulate Strum Delay with the LFO using sine waveform to create pulsing strums or triangle waveform for rhythmic chord movement
  • 04Combine Velocity Scaling and Velocity Direction to emphasize either high or low notes based on pitch order
