Retromulator 2.2

Retromulator is a multi-core retro hardware emulation app and AUv3 plug-in that brings legendary synthesizer, sampler, and keyboard cores back to life through authentic low-level emulation. Each core runs its original firmware, a clean-room controller written from the behaviour of the hardware, a physical model or sample data — delivering the unmistakable character of the hardware that defined electronic music from the early 80s through the 2000s.
