Phase-4

Bitwig

Where to get itIncluded with Bitwig Studio. It is part of that DAW, not a separate download.bitwig.com

Phase-4 is a phase-manipulation synthesizer featuring four unique oscillator units with advanced phase distortion and phase modulation techniques. It combines a flexible tuning system with ratio-based frequency control, a multimode filter capable of audio-rate modulation, and global controls for shaping sound across all oscillators simultaneously. This distinctive architecture makes it ideal for creating complex, evolving timbres through phase-based synthesis.

Written from the manual and checked against it. How we check

Key Features

01Four oscillator units with individual phase distortion and modulation controls
02Phase distortion with multiple algorithms and shapeable waveforms via SHAPE parameter
03Phase modulation with MOD control and per-oscillator modulation attenuators
04Flexible frequency control: keyboard tracking with semitone offset, fixed Hz/kHz mode, and RATIO-based oscillator relationships
05Monophonic and stereo detune modes with polarity inversion
06Eight filter modes: 2 low-pass, 2 band-pass, 2 high-pass, band-reject, and disabled
07Multimode filter with audio-rate modulation and per-oscillator cutoff attenuators
08Dual envelope generators (FEG and AEG) with velocity scaling and independent routing

Things to Try

  • 01Use the X-Y pad to control global SHAPE and MOD parameters together for real-time timbral evolution
  • 02Enable keyboard tracking with semitone offset on multiple oscillators and set different RATIO values (e.g., 1:1, 3:1, 1:2) to create harmonic relationships
  • 03Route individual oscillators to filter cutoff using the bipolar attenuators for dynamic filter modulation
  • 04Apply phase modulation by setting the MOD knob and adjusting individual oscillator modulation amounts to create self-modulation and cross-modulation effects
