Synth2 (sl23): Free Synthesizer Plugin by Dead Channel Audio
Dead Channel Audio has released Synth2 (sl23), a 100% free virtual analog synthesizer plugin for Windows. Built as an enhanced fork of the Oxo Music (Chab15) project, the instrument delivers classic subtractive sound shaping with refreshed usability. Producers can download the VST3 build directly from the developer repository with no registration or sign-up required.
Classic Subtractive Architecture
The core architecture of Synth2 takes heavy inspiration from legendary subtractive workhorses like Synth1. Under the hood, Synth2 (sl23) maintains the responsive audio engine of previous revisions while polishing the interface for modern digital audio workstations. Dual oscillators provide standard analog waveforms alongside frequency modulation (FM), ring modulation, and hard sync modes.
Tonal shaping is handled by a resonant multimode filter featuring low-pass, band-pass, and high-pass slopes with dedicated envelope amount and key tracking. Modulation is fast and flexible, offering dual ADSR envelope generators, tempo-synced LFO routing, and an integrated arpeggiator for rhythmic sequences. Built-in delay, chorus, and distortion stages allow sound designers to finalize patches without external processing.
