New Open Source Plugin - Filt-R (Patreon)

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
