v1.2.3.2LatestJun 18, 2026
Audio Engine — Fixed
Intermittent audio crackle / dropouts during live send-return use are gone — periodic plugin-state snapshots no longer contend with the real-time audio thread (lock-free unless a plugin actually changed)
Side Chain — New
Local side-chain now routes audio — pick a source channel and toggle ON/OFF right in the plugin editor; the selected channel feeds the plugin's side-chain input so compressors, gates and duckers respond
