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.

Other Improvements:

• 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.
