2RuleSynth 3.3: Free Patchable Synth Adds Linux Support, Patchable FX
2RuleSynth 3.3 is a major update to the free patchable virtual-analog synthesizer from independent developer tugrulakyuz. The plugin remains completely free with no sign-up required and runs on Windows, macOS, and now Linux in VST3 and CLAP formats.
What's new in version 3.3
The update focuses on workflow and platform reach:
- Native Linux support (VST3/CLAP)
- Redesigned UI with five oscillator colour schemes, spectrum bars, and master volume in the header
- Patchable multi-FX engine — route cables from any modulation source to effect parameters
- 16-voice polyphony (up from 6) with unison detune and stereo spread per voice
- Sample & hold (random) LFO waveform added
- Four macro controls with MAP mode: draw a cable from a macro to any knob, then set depth by dragging the connection
- Sync waveform option for both oscillators
Modular workflow in a plugin
2RuleSynth distinguishes itself by letting you patch modulation cables directly on the panel, much like a hardware modular. The new macro MAP mode extends this to the effects section, so you can assign a single macro to control filter cutoff, delay time, and reverb mix simultaneously. The developer has released several experimental free plugins over the past few years, including the Phonogène-inspired TugPhonon tape delay.
