Free Retromulator Update Add Wurlitzer 200A, Yamaha OPL3 Emulations - March14, 2026



Retromulator – a free hardware synthesizer emulation plugin – has been updated to version 1.2.

Retromulator 1.2 features two new hardware cores: the Wurlitzer 200A physical model piano and Yamaha OPL3 FM synthesis, along with expanded Akai S1000 browsing and import capabilities.

Here’s what’s new:


New Hardware Cores:

• Wurlitzer 200A: Physical model piano via OpenWurli, ported from ~3,000 lines of Rust to C++ and integrated directly into the JUCE plugin framework. Models the tine, pickup, and tone bars of the classic electric piano with per-voice physics.
• Yamaha OPL3: FM synthesis via Nuked OPL3 v1.8 cycle-accurate emulation by Nuke.YKT, with SBI instrument loading, folder-based bank browsing, and zip import support.

Other Improvements:

• OpenWurli settings panel with live parameter editing via combo and navigation pill.
• Akai S1000 browse folder mode with auto-slice drum mapping and state persistence.
• Akai S1000 ISO/BIN/CUE disk image loading.
• CC20 global tuning support with auto-slice and tuning state recall.
• Import/Export/Delete and drag & drop support for all cores.
• Engine author credits in synth selector.
• Bug fixes.

Availability:

Retromulator is available as a free download for Windows, macOS (including Apple Silicon), and Linux in AAX, AU, VST3, and standalone formats.
