In this video, I checked out Filt-R, a free, open-source filter plugin by the creator of Gate-12 and Time-12. It's a sequencer-based filter where I can modulate both cutoff and resonance using separate envelopes, with detailed visual feedback via background waveform display. I especially liked the MS-20 and Moog filter models for bass sounds. It's very intuitive to use in Bitwig, and it offers better envelope visualization than Bitwig’s own curve modulators.
Main Points Covered:
Filt-R Plugin Basics
Modulates filter frequency and resonance with separate envelopes
Sync options: audio trigger, MIDI trigger, various time divisions
Visual feedback via waveform overlay
Filter Types Available
Linear, Sallen-Key, Moog 303, MS-20, Phaser
Sequencer Features
Envelope sequencing with grid resolution control (e.g., triplets, 16ths)
Global controls for offset, drive, release, cutoff shift
Sound Design Workflow in Bitwig
Used on detuned saw wave + drum loop
Favored MS-20 Bandpass for basslines
Utilized visual feedback to fine-tune envelope curves
Compared different filter responses with EQ Curve Analyzer
Key Advantages
Precise envelope drawing compared to Bitwig's smoother automation
Open-source and free to download on GitHub
Especially useful for acid basslines and creative filter automation
Let me know if you'd like a breakdown of how to set it up in Bitwig or want clarification on any of the filter types! Download: https://bit.ly/4e6DT5T
